| | Simple English article snapshot | Wikipedia contributors; distributed by Wikimedia | CC BY-SA 3.0, as offered by the pinned source dataset | |
| | Chunks, catalog, extracted assertions and Wikipedia vector index | Derived from that snapshot by Commonplace | CC BY-SA 3.0 for the adapted Wikipedia material | |

| The upstream Wikipedia dataset also offers GFDL; this distribution uses its |
| CC BY-SA option. See the preserved [upstream card](provenance/UPSTREAM_DATASET_CARD.md). |
| Full license texts are in [licenses/](licenses). |
|
|
| Source identity and article attribution are preserved in the Parquet data and |
| SQLite catalog. Each article has its original Wikipedia URL; its contributor |
| history is available from the article's History tab. For automated attribution, |
| retain the stored title, URL, source hash, and applicable license alongside |
| returned text. Do not attribute model interpretations to Wikipedia contributors. |
|
|
| The Simple English snapshot was cleaned by the upstream dataset, split into |
| overlapping source-offset passages by Commonplace, encoded into normalized |
| 512-dimensional vectors, and indexed for lexical/entity lookup. Narrow extraction |
| rules derived relationships with source quotations. These are changes to the |
| original representation, not endorsements by Wikimedia or Google. |
|
|
| The encoder is the unmodified pinned upstream payload. The software loading it |
| disables vision/audio configurations for this text-only use; no weights were |
| fine-tuned. Its original model card is retained at [encoder/README.md](encoder/README.md). |
|
|
| There is no blanket software license over all data in this collection. The |
| Commonplace software repository's Apache license does not replace these terms. |
