What is ducksemantics?

ducksemantics puts an ontology graph and ColBERT retrieval inside DuckDB, callable from R.

ducksemantics is a first release, and an unusually complete one. It combines a DuckDB-native semantic graph, lexical grounding, dense retrieval, exact late-interaction scoring, and structured judgment behind a single R API. The release notes report a full HPO ontology load of 19,836 nodes with 202,740 materialized is_a closure rows, plus persisted EmbeddingGemma and LFM2.5-ColBERT vectors, with DuckDB MaxSim agreeing with an external implementation to seven decimal places.

What is duckspatial?

duckspatial rebuilt itself around a lazy DuckDB class, then spent four releases filling in the geometry surface

duckspatial exposes DuckDB's spatial extension to R. In March 2026 it stopped being an sf convenience wrapper: 1.0.0 made duckspatial_df the primary class, a lazy table-like object that stays in DuckDB until explicitly materialized. Every function accepts and returns it by default, with mode = 'sf' as the opt-out. The four releases since have added roughly forty geometry functions on top of that foundation.

ducksemantics puts an ontology graph and ColBERT retrieval inside DuckDB, callable from R.

◆ Current state

ducksemantics is a first release, and an unusually complete one. It combines a DuckDB-native semantic graph, lexical grounding, dense retrieval, exact late-interaction scoring, and structured judgment behind a single R API. The release notes report a full HPO ontology load of 19,836 nodes with 202,740 materialized is_a closure rows, plus persisted EmbeddingGemma and LFM2.5-ColBERT vectors, with DuckDB MaxSim agreeing with an external implementation to seven decimal places.

◆ Where it's heading

With one release on the record there is no trend to read, only a stated posture: correctness first. The release documents transactional and idempotent graph writes, atomic and resumable embedding caches, index preservation across graph projection, and a verified numerical match against a reference MaxSim implementation. That is the profile of a package expecting to be used as infrastructure rather than a demo.

◆ Prediction

Where this goes next is not yet determinable from a single release. The obvious pressure point is ontology coverage beyond the HPO used for validation, but the entries do not indicate a plan.

duckspatial rebuilt itself around a lazy DuckDB class, then spent four releases filling in the geometry surface

◆ Current state

duckspatial exposes DuckDB's spatial extension to R. In March 2026 it stopped being an sf convenience wrapper: 1.0.0 made duckspatial_df the primary class, a lazy table-like object that stays in DuckDB until explicitly materialized. Every function accepts and returns it by default, with mode = 'sf' as the opt-out. The four releases since have added roughly forty geometry functions on top of that foundation.

◆ Where it's heading

The direction is to keep work inside DuckDB and make R the orchestration layer rather than the compute layer. 1.1.0 added macros so duckspatial functions work inside dplyr verbs; 1.1.1 moved the default to DuckDB v1.5.0 native spatial storage so CRS metadata persists in GEOMETRY columns; 1.2.0 added vector-tile output via ddbs_write_mbtiles() and the full family of geometry deserializers. Feature velocity has been high and consistent since the rewrite.

◆ Prediction

The remaining gaps are in PostGIS parity — the deserializers and tile writers landed in 1.2.0, so raster support or spatial indexing are the plausible next targets. 1.2.1 being a single message-capture fix suggests the 1.2.x line is now stabilizing.
