-# Language Data
+# World Language Data Collection
 
-Curated linguistic datasets covering 23,740 languages. Pulls from Glottolog, WALS, PHOIBLE, and Joshua Project, plus original integration work combining them into a single queryable format.
+23,740 languages: Glottolog, WALS, PHOIBLE + integrated world languages
 
-## Datasets
+Curated collection of linguistic datasets with original integration work. Includes geographic coordinates, typological features, phonological inventories, language family trees, and an integrated world languages dataset merging Glottolog, Joshua Project, and language history data. Original work under MIT; source data under CC-BY-4.0 (Glottolog, WALS) and CC-BY-SA-3.0 (PHOIBLE).

+## Usage
 
-**`language-families/`** -- Language family trees, Proto-Indo-European reconstructions, speaker counts. Restructured from Glottolog with enrichment from multiple sources. 10 JSON files covering family hierarchies up to 18 levels deep.
-
-**`historical-corpora/`** -- CLMET historical English corpus metadata.
-
-**`lemmatization/`** -- Historical lemma mappings (738 entries) for normalizing older English texts.
-
-**`reference-corpora/`** -- Brown Corpus part-of-speech statistics.
-
-## The Integrated Dataset
-
-`world_languages_integrated.json` is the main original contribution. It merges four sources by ISO 639-3 code:
+```python
+from datasets import load_dataset
 
-- **Glottolog** -- coordinates, family classification, macroarea (7,040 languages)
-- **Joshua Project** -- speaker populations, demographics (7,130 languages)
-- **Language history** -- family tree positions, historical periods (198 languages)
-- **US indigenous** -- endangerment status, revitalization efforts (13 languages)
+# Load the dataset
+dataset = load_dataset("lukeslp/language-data")
 
-```python
+# Or load from local files
 import json
-
-with open("world_languages_integrated.json") as f:
-    languages = json.load(f)
-
-# Each record looks like:
-# {
-#   "iso_639_3": "eng",
-#   "name": "English",
-#   "glottolog": { "latitude": 53.0, "longitude": -1.0, "family_name": "Indo-European", ... },
-#   "joshua_project": { "population": 379007140, "countries": [...], ... },
-#   "speaker_count": { "count": 379007140, "source": "joshua_project_aggregated", ... },
-#   "data_sources": ["joshua_project", "glottolog"]
-# }
-
-# Find endangered languages with coordinates
-endangered = [
-    lang for lang in languages
-    if lang.get("glottolog", {}).get("latitude")
-    and lang.get("speaker_count", {}).get("count", float("inf")) < 1000
-]
+with open('data.json') as f:
+    data = json.load(f)
 ```
