+# iSign Metadata Reference
+
+This repository is a **metadata-only reference version** of the original dataset:
+
+👉 https://huggingface.co/datasets/Exploration-Lab/iSign
+
+It does **not** contain or redistribute any original video files.  
+Only lightweight metadata is stored.
+
+---
+
+## Purpose
+
+This dataset is created to:
+
+- maintain a reusable metadata copy
+- support preprocessing and dataset engineering workflows
+- avoid duplication of large video files
+- preserve linkage to the original dataset
+- enable downstream annotation or translation pipelines
+
+---
+
+## What this dataset contains
+
+Each row includes:
+
+- `source_dataset` — original dataset name  
+- `source_dataset_url` — link to original dataset  
+- `source_split` — split name (e.g., train)  
+- `source_row_idx` — original row index  
+- `video_id` — derived from `uid`  
+- `text` — associated text  
+- `original_video_ref` — placeholder (not populated)
+
+---
+
+## Source schema
+
+The source dataset (as accessed via Hugging Face) provides:
+
+- `uid`
+- `text`
+
+This dataset maps:
+
+- `video_id ← uid`
+- `text ← text`
+
+No video files or video paths were exposed through the dataset loader.
