Overview#

TerminusDB is an open-source knowledge graph database that provides reliable, private & efficient revision control & collaboration.

LinkML schemas can be compiled down to terminusdb WOQL schemas

To run:

gen-terminusdb personinfo.yaml

Docs#

Experimental generator for TerminusDB

Generates JSON-LD to pass to WOQLQuery().

Assumes an “inference/main” graph if any slots have “is_a” values, because any statements with rdfs:subPropertyOf as the predicate must live in a TerminusDB “inference” graph rather than the “schema” graph. When creating a new TerminusDB database, only the “schema” and “instance” graphs are created. Thus, you may need to e.g. WOQLClient.create_graph(“inference”, “main”).
