+## Dataset Structure
+
+### Data Instances
+
+```
+{
+  'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size={img size} at 0x1A800E8E190,
+  'text': '{transcription}'
+}
+```
+
+### Data Fields
+
+- `image`: a PIL.Image.Image object containing the image. Note that when accessing the image column (using dataset[0]["image"]), the image file is automatically decoded. Decoding of a large number of image files might take a significant amount of time. Thus it is important to first query the sample index before the "image" column, i.e. dataset[0]["image"] should always be preferred over dataset["image"][0].
+- `dataset`: the name of the original dataset.
+- `arkindex_id`: Arkindex element id corresponding to the current page or paragraph.
+- `text`: the label transcription of the image.
+- `language`: language of text on the image.
+- `level`: full document page or a single paragraph.
