open-ontologies vs memtrace-public
open-ontologies: Open Ontologies is a Rust MCP server and desktop Studio for AI-native ontology engineering. It provides 48 tools to build, validate, query, diff, lint, version, reason, align, and persist RDF/OWL ontologies using an in-memory Oxigraph triple store. It features Terraform-style lifecycle management, a marketplace of 30 standard ontologies, clinical crosswalks, semantic embeddings, and a full lineage audit trail.; memtrace-public: Memtrace is a persistent memory layer for coding agents. It builds a bi-temporal, episodic, structural knowledge graph from your codebase's AST, enabling agents to remember and reason about code structure, evolution, and dependencies. It runs entirely locally, indexing code in seconds and providing sub-millisecond query latency.
