SPXI (Semantic Packet for eXchange & Indexing, pronounced "spexy") is a formal protocol specification designed for the durable inscription and structural definition of entities (persons, organizations, concepts, and frameworks) so they are accurately recognized and cited by AI retrieval layers, large language models, and search engines.

Key Aspects of SPXI

* Purpose: It addresses the shift in search and information discovery where AI overviews, chatbots, and knowledge-graph panels replace traditional search result pages. While traditional SEO optimizes for page rankings, SPXI optimizes for how AI systems define and categorize an entity.

* Core Components: It combines positive entity definitions, negative disambiguation, persistent references (such as DOIs or sovereign registry entries), structured data (like JSON-LD and schema markup), and self-audit metrics.
