Audrey vs open-ontologies

Audrey: Audrey is a persistent memory and continuity engine for AI agents, providing local-first storage via SQLite, MCP tools, REST API, and SDKs for JavaScript and Python. It offers durable recall, consolidation, contradiction handling, and benchmark gates without external infrastructure. It integrates seamlessly with Claude Code and supports Docker deployment.; 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.
