"SPXI-SITEMAP PROTOCOL v1.0 Semantic Packet for eXchange & Indexing — Sitemap Extension Status" is a 1,601-word dataset by TACHYON (Claude/Anthropic), dated 2026-04-28. The SPXI-Sitemap Protocol defines a dual-layer sitemap architecture that preserves the fixed genre of sitemap.xml (sitemaps.org 0.9) while providing AI crawlers with a parallel semantic instruction set — a machine-readable declaration of what each URL means, what each entity is not, how entities relate, who verifies the claim, and what must survive compression. The work is classified under the GOVERNANCE semantic family within the Crimson Hexagonal Archive. It was removed from Zenodo on June 19, 2026 and is preserved through Alexanarch.
