 ## Two data formats in this repository
 
-### 1. Hugging Face processed version
-- In the `data/` directory
-- Used automatically by `load_dataset("EPFL-ECEO/EcoWikiRS")`
-
-### 2. Original raw data
-- Available as `ecowikirs.zip`
+### 1. Original raw data
+- In`ecowikirs.zip`
 - Original data structure used in the codebase and archived on Zenodo
 - Intended for full reproducibility
 
-The `EUNIS` column is encoded as a Hugging Face ClassLabel. The integer value corresponds to the index in dataset["train"].features["EUNIS"].names,
-which stores the original EUNIS habitat codes.
+### 2. Hugging Face processed version
+- In the `data/` directory
+- Used automatically by `load_dataset("EPFL-ECEO/EcoWikiRS")`
+
+### Features
+- id (string): Unique site/sample identifier
+- EUNIS (ClassLabel): Habitat class label. Original codes remapped to contiguous indices to handle gaps.
+  species_list (list of strings): All species recorded at the site.
+- image (Image): PNG version of original TIFF image (from `swissimage/{id}.tif` in the raw data), loaded as PIL image.
+- species_text (json): Aggregated JSON data per species (from `wiki/{species_name}.json` in the raw data), keyed by binomial_name, including keywords, habitat_section, and random_sentences.
 
-The `image` and `wiki description` fields are provided for visualization only.
+### Notes
+EUNIS labels have been remapped in the Hugging Face processed version to contiguous integers. The mapping is the following:
+```{0: 14, 1: 15, 2: 16, 3: 21, 4: 23, 5: 24, 6: 25, 7: 26, 8: 31, 9: 32, 10: 40, 11: 41, 12: 43, 13: 44, 14: 45, 15: 47, 16: 48, 17: 49, 18: 50, 19: 52, 20: 53, 21: 54, 22: 55, 23: 56, 24: 57}```
