Semantica v0.6.7
Released: 2026-08-28
Tag: v0.6.7 · Compare: v0.6.6...v0.6.7 · PyPI: semantica 0.6.7
Highlights
Feature release, plus one SSRF hardening fix and a large batch of correctness fixes across the RDF/ontology export pipeline.
Ships: first-class LangChain integration (semantica[langchain]), a SAP OData ingestor (semantica[ingest-sap]), ContextGraph Markdown round-trip persistence, a reasoning Action layer (rule-driven Assert/Retract/Call/EmitEvent with optional provenance), a public run_shacl_validation API, and a read-only Explorer Markdown content viewer.
Also fixes: Agno/OpenClaw SSRF hardening, PipelineBuilder.set_parallelism() now actually parallelizes independent steps, flatten_dict() no longer drops data on a key collision, Config.get() honors boolean environment overrides, the MCP server's export_graph tool works again on every format, and a dozen ontology/RDF export correctness bugs (OWL property/class export, SHACL target namespace, one canonical confidence datatype, reachable OWL-Time reification, JSON-LD default-graph and content-derived document identity, full metadata passthrough — see CHANGELOG.md for the full breakdown).
