Sources & licensing

Where the data comes from

Every athlete page on House of Grapplers combines structured fact data (records, match history, weight class, team) with long-form profile content. Each source carries its own license and we surface that on the page where the content is rendered.

• Wikipedia / Wikidata — long-form bios are drafted from Wikipedia article extracts and Wikidata facts, both licensed CC BY-SA 4.0 / CC0. Each article cites its Wikipedia source in the “Sources” block at the bottom.
• Editorial — original commentary, style breakdowns, rivalry narratives, and curated quotes are authored or commissioned by HoG. Marked “proprietary” in our records.
• Public APIs — Reddit, YouTube, and Spotify metadata is fetched via their official APIs and embedded or linked. We do not store full third-party content beyond what their developer terms permit.
• Community submissions — corrections, weigh-ins, and quote suggestions submitted by HoG members.

CC BY-SA 4.0 attribution

Articles drafted from Wikipedia content are derivative works under CC BY-SA 4.0. Per the license, the adapted text on House of Grapplers is offered under the same license, with attribution to the original Wikipedia article. The Sources block on every applicable athlete page links to the source article and identifies its license.

Structured data we contribute back to Wikidata (e.g. match results, weigh-in data) is dedicated to the public domain under CC0.
