Persisting Java objects with RDF in your application requires few easy steps:
This basically means that every class or interface you intend to use within RDFBeans framework must obey general JavaBeans conventions: that is, the classes must have a public no-argument constructor and classes and interfaces must declare conventionally named getter and setter methods for the fields you plan to map to RDF properties. Serializability of the classes is not required.
RDFBean type declaration (@RDFBean) declares that the class or interface is an RDFBean mapped to specified RDF type:
@RDFBean("http://xmlns.com/foaf/0.1/Person") public class Person { ...
Property declarations (@RDF) are applied to the getter methods of the data properties to declare their RDF counterparts:
@RDF("http://xmlns.com/foaf/0.1/name") public String getName() { ...
Identifier property declaration (@RDFSubject) is applied to a single getter method to mark that it returns an unique String value identifying an RDFBean instance.
Identifiers in RDF are URIs, so this method must either return a valid absolute URI, or a namespace prefix should be declared to construct the URI from the prefix value and the String, returned by the method:
@RDFSubject public String getUri() { ... // -- must return absolute URI
or
@RDFSubject(prefix="http://some.uri.prefix/") public String getId() { ... // -- returns an arbitrary string
For complete specification of RDFBeans annotation conventions and examples, please refer to RDFBeans classes and interfaces format specification.
Set up and configure an RDF2Go-supported RDF framework (Sesame or Jena) as a back-end to store RDF representations of your RDFBeans classes.
Add, retrieve, modify and delete your RDFBean objects using RDFBeanManager class and RDF2Go Model implementation, as it’s shown below on this page.
Before you start, you need to decide which of two databinding techniques supported by RDFBeans framework to be used.
The first method is based on use of RDFBean classes and it is much more like a traditional JavaBeans persistence technique. Here you declare a RDFBean class with no-argument constructor, instantiate it and manipulate with properties data. At any time, you can dump (marshal) the object state to the RDF model and retrieve it from there.
The second method is based purely on the RDFBean interfaces. In this case, the special proxy objects are created dynamically to access the RDF data directly through RDFBean methods. Setting of a RDFBean property causes immediate update of the RDF model and the getter methods return actual values, retrieved from the model, so you don’t have to bother about state synchronization between your object model and RDF resources.
It is completely up to you which one method you should use in your application. Moreover, it is perfectly ok to use both methods at the same time and on the same RDF model.
RDFBeans databinding functions are accessible as methods of a single RDFBeanManager class. An RDFBeanManager instance is created with a RDF2Go Model which provides an abstraction layer to access an underlying physical RDF storage. Currently, RDF2Go project provides implementations of Model interface (adapters) for Sesame 2.x and Jena frameworks.
A Model instance is passed as an argument to the RDFBeanManager constructor. The Model implementations may require the model to be opened (initialized) before and closed after use. The following example illustrates how to setup RDFBeans databinding with a model adapter determined automatically via RDF2Go ModelFactory mechanism:
import org.cyberborean.rdfbeans.RDFBeanManager; import org.ontoware.rdf2go.ModelFactory; import org.ontoware.rdf2go.RDF2Go; import org.ontoware.rdf2go.model.Model; ... ModelFactory modelFactory = RDF2Go.getModelFactory(); Model model = modelFactory.createModel(); model.open(); RDFBeanManager manager = new RDFBeanManager(model); ... model.close();
An example with hardcoded Sesame 2.x NativeStore model implementation:
import org.cyberborean.rdfbeans.RDFBeanManager; import org.ontoware.rdf2go.model.Model; import org.openrdf.rdf2go.RepositoryModel; import org.openrdf.repository.Repository; import org.openrdf.repository.sail.SailRepository; import org.openrdf.sail.nativerdf.NativeStore; ... Repository repository = new SailRepository(new NativeStore(new File("~/.sesame/test"))); repository.initialize(); Model model = new RepositoryModel(repository); model.open(); RDFBeanManager manager = new RDFBeanManager(model); ... model.close();
For detailed information on RDF2Go configuration for specific triple store adapters, please refer to RDF2Go documentation.
To add (marshall) a current state of an RDFBean object into the underlying RDF model, there is add() method:
Person person = new Person(); person.setId("http://example.com/persons/jdoe"); person.setName("John Doe"); ... Resource r = manager.add(person);
If the RDFBean is not anonymous (i.e. has a not-null property annotated with @RDFSubject - see RDFBean format), the method returns org.ontoware.rdf2go.model.node.Resource object, representing an URI of RDF resource created in the model. Otherwise, the Resource result represents a org.ontoware.rdf2go.model.node.BlankNode instance.
update() method synchronizes the state of an RDFBean instance and the state of its RDF representation of in the model:
... person.setEmail("john.doe@example.com"); Resource r = manager.update(person);
The code above sets new property of our Person instance and updates it in the RDF model, thus synchronizing the RDF resource with the actual object state. Note that this method works properly only with unanonymous RDFBeans - otherwise, it would insert another BlankNode into the model (i.e. has the same behaviour as add()).
RDFBean class instances can be retrieved (unmarshalled) from their RDF representations using get() method:
... Person person2 = manager.get("http://example.com/persons/jdoe", Person.class);
This method returns new instance of specified RDFBean class filled with data retrieved from the RDF model.
In the example above, we assume that the RDFBean identifier has been declared without namespace prefix. Otherwise, we would have to pass only the local part of the identifier URI as an argument:
... // assuming 'http://example.com/persons/' is a prefix Person person2 = manager.get("jdoe", Person.class);
The get() method returns null if no RDF resource matching the given RDFBean identifier and class is found.
If we already have an RDF resource URI or a BlankNode (returned by add() or update() methods for instance), we can retrive the matching RDFBean instance using that value:
... Person person2 = (Person) manager.get(r);
The getAll() method iterates over all RDFBeans of a specified class in the model:
// Displays the names of all Persons in the model: ClosableIterator iter = manager.getAll(Person.class); while (iter.hasNext()) { Person p = (Person)iter.next(); System.out.println(p.getName()); } iter.close();
This is an alternative mapping technique which is based on using RDFBean interfaces and dynamic proxy objects.
Let’s extract the interface from our RDFBean Person class and annotate it the same way:
@RDFBean("http://xmlns.com/foaf/0.1/Person") public interface IPerson { @RDFSubject String getId(); @RDF("http://xmlns.com/foaf/0.1/name") String getName(); ...
As we have this interface, we can map it directly to an RDF resource in the model. For that, we need to obtain an instance of the dynamic proxy object from RDFBeanManager:
IPerson person = manager.create("http://example.com/persons/jdoe", IPerson.class);
The create() method returns an object implementing our IPerson interface and matching the RDFBean with the specified identifier in the model. This proxy object has the same behaviour as an instance of the class implementing that interface, with the exception that all its data is stored not in the Java heap, but directly in the underlying RDF model. So, the call:
person.setName("John Doe");
will cause a statement with RDF property http://xmlns.com/foaf/0.1/name and the given literal value to be created or updated in the model. Similarly, the getName() method of the proxy would return this value addressing directly to that statement.
If no resource matching the specified RDFBean identifier exists in the model, create() returns an empty instance, that is all its getXXX() methods return nulls. The underlying RDF model will be unchanged until the first setXXX() method is called.
To instantiate the proxy objects for existing RDFBeans, the create() method with a Resource argument can be used. The method returns null if the specified Resource doesn’t exist in the model:
IPerson person = manager.create(r);
The reference to the Resource can be obtained with getResource() method (see {Resolving RDFBean identifiers} below), or by querying the underlying RDF model (see Querying the model).
If an RDFBean identifier is known, it can be resolved to an RDF resource using the identifier’s String value and RDFBean class:
... Resource r = manager.getResource("http://example.com/persons/jdoe", Person.class);
or, if a namespace prefix is set for identifiers:
... // assuming 'http://example.com/persons/' is a prefix Resource r = manager.getResource("jdoe", Person.class);
The method returns null if no matching Resource is found in the model.
add() and update() methods performs cascade databinding, that is if a marshalling object has other RDFBeans as its properties, they are marshalled and added to the model recursively. It allows to manipulate with the whole complex object models with single method calls.
For example, let the Person class declares a knows property (probably, mapped to foaf:knows) to link Persons one another (for simplicity, put cardinality of this property to 1):
Person john = new Person(); john.setId("http://example.com/persons/john"); ... Person mary = new Person(); mary.setId("http://example.com/persons/mary"); ... john.setKnows(mary);
Calling manager.add(john) will result in adding both objects (john and mary) and generating a statement to relate their RDF representations with the knows property.
Similarly, on retrieving the john object, the mary RDFBean will be automatically unmarshalled and assigned to john.knows property, thus reconstructing the whole graph of related objects.
The dynamic proxies follow the same principle: when a getter method is called and the property references to another RDFBean, the proxy object is automatically created and returned:
IPerson john = manager.create("http://example.com/persons/john", IPerson.class); IPerson mary = manager.create("http://example.com/persons/mary", IPerson.class); john.setKnows(mary); ... john.getKnows().setName("Mary"); // getKnows() returns the proxy equals to mary System.out.println(mary.getName()); // -- will be "Mary"
By default, each call of add(), update() or delete() methods will commit the transaction into a RDF store after an operation is completed. This behaviour can be changed by setting the autocommit mode to false with setAutocommit() method. If autocommit is off, the transactions can be commited by explicit calling of the commit() method of a underlying RDF2Go Model interface:
// Adding multiple RDFBeans as a single transaction: manager.setAutocommit(false); for (Person p: persons) { manager.add(p); } manager.getModel().commit();
Note that the autocommit mode in RDFBeanManager is unrelated to the autocommit settings of the underlying model. RDFBeanManager operations always set the autocommit flag of the model to false to avoid commiting every single RDF triple.
If dynamic proxies are used and autocommit mode is on, every setter method call will commit a transaction. You can turn the autocommit off for manual transaction management:
manager.setAutocommit(false); IPerson john = manager.create("http://example.com/persons/john", IPerson.class); john.setName("John"); System.out.println(john.getName()); // -- will be null manager.getModel().commit(); System.out.println(john.getName()); // -- and now it is "John"
RDFBeans framework does not include its own facilities to query the RDF model, but it is possible to query the underlying RDF2Go model and retrieve RDFBean objects from results.
Example of querying with the triple patterns:
// Find all persons with Google as a workplace homepage: Set<Person> results = new HashSet<Person>(); URI predicate = model.createURI("http://xmlns.com/foaf/0.1/workplaceHomepage"); URI object = model.createURI("http://google.com"); ClosableIterator<Statement> ci = model.findStatements(Variable.ANY, predicate, object); while (ci.hasNext()) { Resource r = ci.next().getSubject(); results.add((Person)manager.get(r)); } ci.close();
Example of using Sparql:
Set<Person> results = new HashSet<Person>(); ClosableIterator<QueryRow> ci = model.sparqlSelect( "SELECT ?r WHERE { ?r <http://xmlns.com/foaf/0.1/workplaceHomepage> <http://google.com> . }" ).iterator(); while (ci.hasNext()) { Resource r = ci.next().getValue("r").asResource(); results.add((Person)manager.get(r)); } ci.close();

Our Story
It all started with a clash
Not so long ago, these two met during an office event. Our boy doesn't even remember this exactly. But he managed to make a negative impression on the girl. She had been holding the grudge for sometime. She never had a clue that he was the one she is going to deal with for the whole life.
Few months later, their paths started crossing often.  So, it was inevitable they started talking to each other. Common interests brought them closer. Getting to know each other, they formed a mutual respect for each other.
Time went by and they became friends. They could not stay friends for so long. Then, the story is the same old. What started as exchanging looks now ends with exchanging vows. The best is yet to be!
It takes more than two!
It's never easy. It took a lot of time and effort to make this come true. We will be so glad to have you all to be there with us on the best day of our life.

‘Marriage Story’ tops Golden Globe nominations with six
by Agency Report“Marriage Story,” Netflix’s heart-wrenching divorce saga, topped the Golden Globe nominations Monday with six nods including best drama, kicking off the race for the Oscars.
“The Irishman,” Martin Scorsese’s three-and-a-half-hour gangster epic, and “Once Upon a Time in Hollywood,” Quentin Tarantino’s nostalgic love letter to 1960s Tinseltown, were hot on its heels with five each.

Detailed Description
Rectangle { width: 800 height: 600 color: "black" MediaPlayer { id: player source: "file://video.webm" autoPlay: true } VideoOutput { id: videoOutput source: player anchors.fill: parent } }
The VideoOutput item supports untransformed, stretched, and uniformly scaled video presentation. For a description of stretched uniformly scaled presentation, see the fillMode property description.
The VideoOutput item works with backends that support either QVideoRendererControl or QVideoWindowControl. If the backend only supports QVideoWindowControl, the video is rendered onto an overlay window that is layered on top of the QtQuick window. Due to the nature of the video overlays, certain features are not available for these kind of backends:
- Some transformations like rotations
- Having other QtQuick items on top of the VideoOutput item
Most backends however do support QVideoRendererControl and therefore don't have the limitations listed above.
See also MediaPlayer and Camera.
Property Documentation
This property allows you to enable and disable auto orientation of the video stream, so that its orientation always matches the orientation of the screen. If autoOrientation
is enabled, the orientation
property is overwritten.
By default autoOrientation
is disabled.
This QML property was introduced in QtMultimedia 5.2.
See also orientation.
This property holds the item coordinates of the area that would contain video to render. With certain fill modes, this rectangle will be larger than the visible area of the VideoOutput
.
This property is useful when other coordinates are specified in terms of the source dimensions - this applied for relative (normalized) frame coordinates in the range of 0 to 1.0.
Areas outside this will be transparent.
See also mapRectToItem() and mapPointToItem().
Set this property to define how the video is scaled to fit the target area.
- Stretch - the video is scaled to fit.
- PreserveAspectFit - the video is scaled uniformly to fit without cropping
- PreserveAspectCrop - the video is scaled uniformly to fill, cropping if necessary
The default fill mode is PreserveAspectFit.
This property holds the list of video filters that are run on the video frames. The order of the filters in the list matches the order in which they will be invoked on the video frames. The objects in the list must be instances of a subclass of QAbstractVideoFilter.
See also QAbstractVideoFilter.
In some cases the source video stream requires a certain orientation to be correct. This includes sources like a camera viewfinder, where the displayed viewfinder should match reality, no matter what rotation the rest of the user interface has.
This property allows you to apply a rotation (in steps of 90 degrees) to compensate for any user interface rotation, with positive values in the anti-clockwise direction.
The orientation change will also affect the mapping of coordinates from source to viewport.
See also autoOrientation.
source : variant |
This property holds the source item providing the video frames like MediaPlayer or Camera.
If you are extending your own C++ classes to interoperate with VideoOutput, you can either provide a QObject based class with a mediaObject
property that exposes a QMediaObject derived class that has a QVideoRendererControl available, or you can provide a QObject based class with a writable videoSurface
property that can accept a QAbstractVideoSurface based class and can follow the correct protocol to deliver QVideoFrames to it.
This property holds the area of the source video content that is considered for rendering. The values are in source pixel coordinates, adjusted for the source's pixel aspect ratio.
Note that typically the top left corner of this rectangle will be 0,0
while the width and height will be the width and height of the input content. Only when the video source has a viewport set, these values will differ.
The orientation setting does not affect this rectangle.
See also QVideoSurfaceFormat::pixelAspectRatio() and QVideoSurfaceFormat::viewport().
Method Documentation
Given normalized coordinates point (that is, each component in the range of 0 to 1.0), return the mapped point that it corresponds to (in item coordinates). This mapping is affected by the orientation.
Depending on the fill mode, this point may lie outside the rendered rectangle.

Moving an Object
You can move an object to a new location in the file in several different ways:
Note that to move an object from the Contents View, you must drag it from the cell containing the object's icon.
If the location you want to drag the object to is not visible, you can hold the object you are dragging near the top or bottom of the view, and it will scroll up or down for you.
Note: The location of objects does not affect their ability to be linked to by link properties. You can move a folder containing link objects or a linked object to a new location without affecting any current links. For more information, see the Properties and Property Types topic.

Classes
The following classes are available globally.
-
A wrapper around Mentat’s
TypedValue
Rust object. This class wraps a raw pointer to a RustTypedValue
struct and provides accessors to the values according to expected result type.As the FFI functions for fetching values are consuming, this class keeps a copy of the result internally after fetching so that the value can be referenced several times.
Also, due to the consuming nature of the FFI layer, this class also manages it’s raw pointer, nilling it after calling the FFI conversion function so that the underlying base class can manage cleanup.
See moreDeclaration
Swift
open class TypedValue : OptionalRustObject
-
The primary class for accessing Mentat’s API. This class provides all of the basic API that can be found in Mentat’s Store struct. The raw pointer it holds is a pointer to a Store.
See moreDeclaration
Swift
open class Mentat : RustObject
-
This class allows you to construct a query, bind values to variables and run those queries against a mentat DB.
This class cannot be created directly, but must be created through
Mentat.query(String:)
.The types of values you can bind are
Int64
Entid
Keyword
Bool
Double
Date
String
UUID
.
Each bound variable must have a corresponding value in the query string used to create this query.
let query = """ [:find ?name ?cat :in ?type :where [?c :community/name ?name] [?c :community/type ?type] [?c :community/category ?cat]] """ mentat.query(query: query) .bind(varName: "?type", toKeyword: ":community.type/website") .run { result in ... }
Queries can be run and the results returned in a number of different formats. Individual result values are returned as
TypedValues
and the format differences relate to the number and structure of those values. The result format is related to the format provided in the query string.Rel
- This is the defaultrun
function and returns a list of rows of values. Queries that wish to haveRel
results should format their query strings:let query = """ [: find ?a ?b ?c : where ... ] """ mentat.query(query: query) .run { result in ... }
Scalar
- This returns a single value as a result. This can be optional, as the value may not be present. Queries that wish to haveScalar
results should format their query strings:let query = """ [: find ?a . : where ... ] """ mentat.query(query: query) .runScalar { result in ... }
Coll
- This returns a list of single values as a result. Queries that wish to haveColl
results should format their query strings:let query = """ [: find [?a ...] : where ... ] """ mentat.query(query: query) .runColl { result in ... }
Tuple
- This returns a single row of values. Queries that wish to haveTuple
results should format their query strings:let query = """ [: find [?a ?b ?c] : where ... ] """ mentat.query(query: query) .runTuple { result in ... }
Declaration
Swift
open class Query : OptionalRustObject
-
Wraps a
Rel
result from a Mentat query. ARel
result is a list of rows ofTypedValues
. Individual rows can be fetched or the set can be iterated.To fetch individual rows from a
RelResult
userow(Int32)
.query.run { rows in let row1 = rows.row(0) let row2 = rows.row(1) }
To iterate over the result set use standard iteration flows.
query.run { rows in rows.forEach { row in ... } }
Note that iteration is consuming and can only be done once.
See moreDeclaration
Swift
open class RelResult : OptionalRustObject
-
Iterator for
RelResult
.To iterate over the result set use standard iteration flows.
query.run { result in rows.forEach { row in ... } }
Note that iteration is consuming and can only be done once.
See moreDeclaration
Swift
open class RelResultIterator : OptionalRustObject, IteratorProtocol
-
Wraps a
Tuple
result from a Mentat query. ATuple
result is a list ofTypedValues
. Individual values can be fetched asTypedValues
or converted into a requested type.Values can be fetched as one of the following types:
TypedValue
Int64
Entid
Keyword
Bool
Double
Date
String
UUID
.
Declaration
Swift
open class TupleResult : OptionalRustObject
-
Wraps a
Coll
result from a Mentat query. AColl
result is a list of rows of single values of typeTypedValue
. Values for individual rows can be fetched asTypedValue
or converted into a requested type.Row values can be fetched as one of the following types:
TypedValue
Int64
Entid
Keyword
Bool
Double
Date
String
UUID
.
Declaration
Swift
open class ColResult : TupleResult
-
Iterator for
ColResult
.To iterate over the result set use standard iteration flows.
query.runColl { rows in rows.forEach { value in ... } }
Note that iteration is consuming and can only be done once.
See moreDeclaration
Swift
open class ColResultIterator : OptionalRustObject, IteratorProtocol
-
Base class that wraps an optional
See moreOpaquePointer
representing a pointer to a Rust object. This class should be used to wrap Rust pointer that point to consuming structs, that is, calling a function for that Rust pointer, will cause Rust to destroy the pointer, leaving the Swift pointer dangling. These classes are responsible for ensuring that their rawOpaquePointer
arenil
led after calling a consuming FFI function. This class provides cleanup functions on deinit, ensuring that all classes that inherit from it will have theirOpaquePointer
destroyed when the Swift wrapper is destroyed. If a class does not overridecleanup
then afatalError
is thrown. The optional pointer is managed here such that is the pointer is nil, then the cleanup function is not called ensuring that we do not double free the pointer on exit.Declaration
Swift
open class OptionalRustObject : Destroyable
-
Base class that wraps an non-optional
See moreOpaquePointer
representing a pointer to a Rust object. This class provides cleanup functions on deinit, ensuring that all classes that inherit from it will have theirOpaquePointer
destroyed when the Swift wrapper is destroyed. If a class does not overridecleanup
then afatalError
is thrown.Declaration
Swift
open class RustObject : Destroyable
-
This class wraps a raw pointer that points to a Rust
EntityBuilder<InProgressBuilder>
object.EntityBuilder
provides a programmatic interface to performing assertions on a specific entity. It provides functions for adding and retracting values for attributes for an entity within an in progress transaction.The
transact
function will transact the assertions that have been added to theEntityBuilder
and pass back theTxReport
that was generated by this transact and theInProgress
that was used to perform the transact.  }
The
commit
function will transact and commit the assertions that have been added to theEntityBuilder
. It will consume theInProgress
used to perform the transact. It returns theTxReport
generated by the transact. After callingcommit
, a new transaction must be started by callingMentat.beginTransaction()
in order to perform further actions.
See morelet aEntid = txReport.entid(forTempId: "a") do { let builder = try mentat.entityBuilder(forEntid: aEntid) try builder.add(keyword: ":foo/boolean", boolean: true) try builder.add(keyword: ":foo/instant", date: newDate) let report = try builder.commit() ... } catch { ... }
Declaration
Swift
open class EntityBuilder : OptionalRustObject
-
This class wraps a raw pointer that points to a Rust
InProgress
object.InProgress
allows for multiple transacts to be performed in a single transaction. Each transact performed results in aTxReport
that can be used to gather information to be used in subsequent transacts.Committing an
InProgress
commits all the transacts that have been performed using thatInProgress
.Rolling back and
InProgress
rolls back all the transacts that have been performed using thatInProgress
.do { let inProgress = try mentat.beginTransaction() let txReport = try inProgress.transact(transaction: "[[:db/add "a" :foo/long 22]]") let aEntid = txReport.entid(forTempId: "a") let report = try inProgress.transact(transaction: "[[:db/add "b" :foo/ref \(aEntid)] [:db/add "b" :foo/boolean true]]") try inProgress.commit() } catch { ... }
InProgress
also provides a number of functions to generating an builder to assert datoms programatically. The two types of builder areInProgressBuilder
andEntityBuilder
.InProgressBuilder
takes the currentInProgress
and provides a programmatic interface to add and retract values from entities for which there exists anEntid
.  }
EntityBuilder
takes the currentInProgress
and either anEntid
or atempid
to provide a programmatic interface to add and retract values from a specific entity. The providedInProgress
is used to perform the transacts.
See moredo { let transaction = try mentat.beginTransaction() let builder = try transaction.builder(forTempId: "b") try builder.add(keyword: ":foo/boolean", boolean: true) try builder.add(keyword: ":foo/instant", date: newDate) let (inProgress, report) = try builder.transact() let bEntid = report.entid(forTempId: "b") try inProgress.transact(transaction: "[[:db/add \(bEntid) :foo/long 22]]") try inProgress.commit() } catch { ... }

Interoperability Repository
The Things Stack expects the root of interoperability repository to contain config.yml
, which contains various interoperablity configuration options:
join-servers: # list of Join Server interoperability configurations,
# used to map a JoinEUI to the Join Server
- file: './path/js.yml' # relative path to a file containing Join Server configiration
join-euis: # list of Join EUI prefixes the Join Server should handle
- '11aa000000000000/16'
All paths are relative to the file they are defined in, that is example/js.yml
defined in interopconf/config.yml
is expected to be located at interopconf/example/js.yml
.
For join-servers
, in case Join EUI prefixes overlap, the most specific prefix takes precedence.
The Things Stack servers always first try cluster-local Join Server and if it’s not found or the device is not found, fallback to the external one via interoperability.
0000000000000000/0
prefix matches all JoinEUIs
, while being the least specific, hence it always matches last. Use this prefix if you wish to define a “fallback” Join Server interoperability configuration.
For example, consider config.yml
as follows:
join-servers:
- file: './example/js.yml'
join-euis:
- 'abcd000000000000/16'
- 'dcba000000000000/16'
- file: './fallback/js.yml'
join-euis:
- '0000000000000000/0'
A configuration like this would make Join Server requests for JoinEUIs starting with ABCD
or BCDA
to be handled by Join Server defined at example/js.yml
in interoperability mode and all other ones to be handled by Join Server defined at fallback/js.yml
.
The Join Server configuration provides means to configure how the components interact with the Join Server. The configuration supports multiple options:
fqdn: 'thethings.example' # FQDN of the Join Server, if unset, it is resolved via LoRa Alliance DNS
port: 12345 # port to connect at, if unset, 443 is used
protocol: 'BI1.0' # protocol to use - one of BI1.0 or BI1.1
paths: # custom URI paths to use for various requests, if unset, the FQDN is used
join: 'some/path' # the URI path to use for JoinReq
rejoin: 'some/other/path' # the URI path to use for RejoinReq
app-s-key: 'other/path' # the URI path to use for AppSKeyReq
home-ns: 'somepath' # the URI path to use for HomeNSReq
tls: # TLS configuration to use
root-ca: 'path/to/clientca.pem' # path to client CA
certificate: 'path/to/clientcert.pem' # path to client TLS certificate
key: 'path/to/clientkey.pem' # path to client TLS key
headers: # HTTP headers to send, defined as key-value map
SomeHeader: 'SomeValue'
Interoperability with Semtech Join Server
An example interoperability repository supporting Semtech Join Server could look like this:
config.yml
:join-servers: - file: './semtech/js.yml' join-euis: - 'ffffffbb00000000/32' - '0016c00000000000/24' # Other Join Servers, e.g. The Things Industries # - file: './tti/js.yml' # join-euis: # - '70b3d57ed0000000/40'
semtech/js.yml
:fqdn: 'js.loracloud.com' port: 7009 protocol: 'BI1.0' paths: join: 'api/v1/rens/rens-1::2/lbi_joinreq' # replace 'rens-1::1' by the RENS issued by Semtech tls: root-ca: './ca.pem' # path to the client CA issued by Semtech certificate: './cert.pem' # path to the client TLS certificate issued by Semtech key: './key.pem' # path to the client TLS key issued by Semtech

array
The array of associated array which has a field name and "omit" keys as like: array(array("FamilyName"=>"Nii", "Country"=>"Japan")). In this example of apply the AND operation for two fields, and "FamilyName" and "Country" are field name. The value can contain the operator: =, ==, !, <, ≤ or <=, >, ≥ or >=, ..., //, ?, @, #, , \, "", ~. If you want to apply the OR operation, describe array of array as like: array(array("FamilyName"=>"Nii"), array("Country"=>"Japan")). If you want to omit records match with condition set the "omit" element as like: array("FamilyName"=>"Nii", "omit"=>"true"). If you want to query all records in the layout, set the first parameter to null.
array
The array of associated array which has "fieldName" and "sortOrder" keys as like: array(array("fieldName"=>"FamilyName", "sortOrder"=>"ascend"), array("fieldName"=>"GivenName", "sortOrder"=>"ascend")). The value of sortOrder key can be 'ascend', 'descend' or value list name.

integer
The number of records contains in the result record set.
array
The array of the portal's object names. The query result is going to contain portals specified in this parameter. If you want to include all portals, set it null or omit it. Simple case is array('portal1', portal2'), and just includes two portals named 'portal1' and 'portal2' in the query result. If you set the range of records to a portal, you have to build associated array as like: array('portal1' => array('offset'=>1,'range'=>5), 'portal2' => null). The record 1 to 5 of portal1 include the query result, and also all records in portal2 do.
array
scripts that should execute right timings. The most understandable description is an associated array with API's keywords "script", "script.param", "script.prerequest", "script.prerequest.param", "script.presort", "script.presort.param", "layout.response." These keywords have to be a key, and the value is script name or script parameter, ex. {"script"=>"StartingOver", "script.param"=>"344|21|abcd"}. If $script is array with one element, it's handled as the value of "script." If $script is array with two elements, these are handled as values of "script" and "layout.response." If it it's three elements, these are "script", "script.param" and "layout.response." If it it's four elements, these are "script.prerequest", "script.presort", "script" and "layout.response."

The default Calendar implementation is a single-select 1-up calendar view that defaults to the current month and year. The basic calendar can be implemented by declaring a variable to represent the calendar, and passing the calendar's ID to the Calendar constructor:
The Calendar object should be instantiated after the body has been rendered, so that a reference to the container element that will contain the calendar can be obtained. The container element can reside anywhere within the body.


--- title: Model EMA (Exponential Moving Average) keywords: fastai sidebar: home_sidebar nb_path: "nbs/01c_training_modelEMA.ipynb" ---
When training a model, it is often beneficial to maintain moving averages of the trained parameters. Evaluations that use averaged parameters sometimes produce significantly better results than the final trained values. {% include note.html content='A smoothed version of the weights is necessary for some training schemes to perform well. Example Google’s hyper-params for training MNASNet, MobileNet-V3, EfficientNet, etc that use RMSprop with a short 2.4-3 epoch decay period and slow LR decay rate of .96-.99 requires EMA smoothing of weights to match results.' %}
timm
supports EMA similar to tensorflow.
To train models with EMA simply add the --model-ema
flag and --model-ema-decay
flag with a value to define the decay rate for EMA.
To keep EMA from using GPU resources, set device='cpu'. This will save a bit of memory but disable validation of the EMA weights. Validation will have to be done manually in a separate process, or after the training stops converging. {% include note.html content='This class is sensitive where it is initialized in the sequence of model init, GPU assignment and distributed training wrappers.' %}
python train.py ../imagenette2-320 --model resnet34
python train.py ../imagenette2-320 --model resnet34 --model-ema --model-ema-decay 0.99
The above training script means that when updating the model weights, we keep 99.99% of the previous model weights and only update 0.01% of the new weights at each iteration.
python"
model_weights = decay * model_weights + (1 - decay) * new_model_weights
Inside timm
, when we pass --model-ema
flag then timm
wraps the model class inside ModelEmaV2
class which looks like:
class ModelEmaV2(nn.Module):
def __init__(self, model, decay=0.9999, device=None):
super(ModelEmaV2, self).__init__()
# make a copy of the model for accumulating moving average of weights
self.module = deepcopy(model)
self.module.eval()
self.decay = decay
self.device = device # perform ema on different device from model if set
if self.device is not None:
self.module.to(device=device)
def _update(self, model, update_fn):
with torch.no_grad():
for ema_v, model_v in zip(self.module.state_dict().values(), model.state_dict().values()):
if self.device is not None:
model_v = model_v.to(device=self.device)
ema_v.copy_(update_fn(ema_v, model_v))
def update(self, model):
self._update(model, update_fn=lambda e, m: self.decay * e + (1. - self.decay) * m)
def set(self, model):
self._update(model, update_fn=lambda e, m: m)
Basically, we initialize the ModeEmaV2
by passing in an existing model
and a decay rate, in this case decay=0.9999
.
This looks something like model_ema = ModelEmaV2(model)
. Here, model
could be any existing model as long as it's created using the timm.create_model
function.
Next, during training especially inside the train_one_epoch
, we call the update
method of model_ema
like so:
if model_ema is not None:
model_ema.update(model)
All parameter updates based on loss
occur for model
. When we call optimizer.step()
, then the model
weights get updated and not the model_ema
's weights.
Therefore, when we call the model_ema.update
method, as can be seen, this calls the _update
method with update_fn = lambda e, m: self.decay * e + (1. - self.decay) * m)
.
{% include note.html content='Basically, here, e
refers to model_ema
and m
refers to the model
whose weights get updated during training. The update_fn
specifies that we keep self.decay
times the model_ema
and 1-self.decay
times the model
. ' %}
Thus when we call the _update
function it goes through each of the parameters inside model
and model_ema
and updates the state for model_ema
to keep 99.99% of the existing state and 0.01% of the new state.
{% include note.html content='Note that model
and model_ema
have the same keys inside the state_dict
.' %}


Mines
Try to expose every square in the grid that is not one of the hidden mines, without opening any square that is a mine.
Click in a square to open it. Every opened square is marked with the number of mines in the surrounding 8 squares, if there are any; if not, all the surrounding squares are automatically opened.
Right-click in a square to mark it with a flag if you think it is a mine. If a numbered square has exactly the right number of flags around it, you can click in it to open all the squares around it that are not flagged.
The first square you open is guaranteed to be safe, and (by default) you are guaranteed to be able to solve the whole grid by deduction rather than guesswork. (Deductions may require you to think about the total number of mines.)

Distraught buyer reveals the EIGHTY flaws in his new-build £210,000 Persimmon house
TV presenter George Clarke has branded the property 'shocking' after home owner Darren Harris complained about the state it was in
by James RodgerA distraught home owner says his new build home has EIGHTY defects.
The £210,000 four-bed build has a raft of issues, says Darren Harris, who lives in Sutton Coldfield.
Darren claims the neighbours have been laughing at the building.
Now architect and TV presenter George Clarke has spoken out about Mr Harris's problem property.
"This is shocking," admitted Clarke on social media, with scores of Twitter followers replying.
"Utterly shocking," agreed another, while a fellow Twitter user wrote: "Imagine the stuff you can’t see!"
"Oh my life! Did the bricklayer take part in Take Your Child To Work?" asked another.
"So the moral of the story is.... Do not buy off plan!" chipped in a fellow Twitter user.
"Poor guy," wrote another, and another said: "Absolute madness."
Rather than being the perfect home, it has given Mr Harris problems from "day one".
Persimmon, who built the house, say they are aware of the concerns and "are working to reach a satisfactory conclusion".
"In June, I got the keys to my house and we drove down to the property," he said.
"The neighbours came over and asked me if I had seen the brickwork on the back of the house.
"They said to me 'We have been having a bit of a laugh and a giggle'."
When Mr Harris took a look, he was confronted with wavy brickwork that wasn't straight and looked unsightly.
The 53-year-old civil engineer was shocked.
"I know all about brickwork. I'm a builder myself, and have run my own company for 36 years," he said.
But the walls were just the start of his problems.
As he entered his finished house for the first time, he tried to put the key in the door.
But the door wouldn't budge.
"We couldn't get in," he said. "I thought there must be a problem and went back to the site office.
"A Persimmon agent came back with me and in the end, he had to shoulder-barge the door to get it open."
It turned out the door frame had been fitted badly. But the problems carried on.
Mr Harris said: "Everything is appallingly built - the workmanship is just shoddy.
"The problems are unbelieveable."
Mr Harris bought the house at Martello Park, Pembroke before it was built.
Together with his wife, who is an area manager for Greggs, he has a number of buy-to-let properties in Pembrokeshire.
He had planned to rent out the house once it had been completed.
"As well as the poor brickwork, we have found paving slabs have been laid straight onto rubble and earth, without any cement," he said.
"The ground isn't level in the garden, the drain covers are sticking out of the ground, and the drains are positioned in the wrong place so the water runs straight past them.
"While I was there, I saw a worker laying some slabs and I could see he was doing it all wrong. I'm a bricklayer by trade, so it was clear to me there were no footings under the paving.
"Even the guttering is all wrong, and not just on my property. None of the guttering reaches the end of the houses and water cascades down the sides when it rains.
"While I was mowing the lawn, I kicked my foot on the raised drain cover and actually broke my foot, causing me to take three weeks off work.
"It's caused my wife and I no end of worry and stress. She has been in tears. If my marriage wasn't so strong this could have finished us."
While Persimmon agreed to rectify some of the issues, the problems persisted and Mr Harris took to fixing the problems himself.
A spokesman for Persimmon Homes West Wales said: "We are aware of Mr Harris’ concerns and we are working to reach a satisfactory conclusion.
"We have many happy customers across South Wales and we take customer service seriously."


This is our country:
BeijingThe Government's Action Plan for Beijing's Construction of Humanities, Transportation, Science and Technology, Transportation and Green Transportation directly put forward the support strategy for bicycle travel. For example, the establishment and improvement of pedestrian and bicycle traffic service projects; the construction of bicycle lanes and pedestrian walkways network to strengthen the management of road rights; the addition of bicycle parking lots in passenger concentrated areas, relying on rail transit stations and bus hubs, set up about 1000 bicycle rental points. Many enterprises have invested in the establishment of free bicycle parking spaces and bicycle storage racks within their units to alleviate the worries of cyclists who commute to work by bicycle. As early as in the early 1980s, in order to encourage cyclists to commute to work, some units paid 5 yuan a month for repairing and wearing bicycles.

Denmark：Building "Bicycle Expressway"
In Copenhagen, half of the residents ride bicycles to work and go to school every day. The city government of Copenhagen has been redesigning streets and formulating bicycle regulations.
But many suburban residents still drive to work for convenience reasons, because the distance to work is too far, the cycling road is too round, the road is too dark, or the road is too old.
The city government of Copenhagen has funded 26 bicycle highways around the capital to encourage people to ride bicycles in and out of Copenhagen.
