 ## Uses
 
-<!-- Address questions around how the dataset is intended to be used. -->
-
 ### Direct Use
 
-<!-- This section describes suitable use cases for the dataset. -->
-
-[More Information Needed]
-
-### Out-of-Scope Use
-
-<!-- This section addresses misuse, malicious use, and uses that the dataset will not work well for. -->
-
-[More Information Needed]
+This dataset is intended to be used for page stream segmentation: the segmentation of a stream of ordered pages into coherent atomic documents.
 
 ## Dataset Structure
 
-<!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->
+Each row of the dataset corresponds to one page of one document. 
+Each page has the following features: 
+- `doc_id`, str: The unique document id this page belongs to
+- `pg_id`, int: The page id within its document
+- `ocr`, str: A string containing the OCR annotations from Microsoft OCR. These can be loaded as a Python dictionary with `json.loads` (or equivalent).
+- `img`, binary: The raw bytes of the page image. These can be converted back to a PIL.Image with `Image.open(io.BytesIO(bytes))` (or equivalent).
 
-[More Information Needed]
+This dataset is given such that each document appears once. 
+To build out the full aggregated synthetic streams, one needs to collate the unique documents according to the streams described in the [streams sub-folder](streams/).
