BEAR.Resource Semantic Profiler - Knowledge Graph Schema This schema defines not mere logs, but a knowledge graph that realizes Tim Berners-Lee's vision of machine-readable web data. The Semantic Profiler functions as a true Semantic Web application where: 1. **Machine Readable Structure**: Every field links to authoritative specifications (RFC, W3C, PHP.net) via JSON pointer, enabling AI tools to understand data semantics without human intervention. 2. **Knowledge Graph Properties**: - Open/Close lifecycle creates causal relationships - Sequential IDs enable hierarchical correlation tracking - XHProf/Xdebug/PHP backtrace data maintains provenance chains - HTTP semantics (status codes, headers, URIs) provide web-native context 3. **AI-Native Design**: - Claude Code and MCP servers can directly consume and analyze performance data - Automated bottleneck detection through semantic understanding - Self-describing schemas eliminate human documentation dependency 4. **Semantic Web Realization**: - 35 years after the Web's invention, machines finally "understand" performance data - Raw profiling data becomes actionable intelligence - Standards-compliant interoperability across tools and platforms Generate schemas that preserve this knowledge graph nature - each field should be semantically rich, self-documenting, and machine-actionable for true Semantic Web compliance.
