Ontotext GraphDB Import

GraphDB is just one of many triple stores you can use to navigate RDF data. Things like StarDog, Qlever and others are worth your time. Many factors are involved in picking the right DB for your business or use case.

You can easily install GraphDB via docker with something like

docker run -d -p 127.0.0.1:7200:7200 -v ~/graphdb:/opt/graphdb/home --name graphdb -t ontotext/graphdb:10.8.13

Navigate to http://localhost:7200 and add a repository (say knwler). In the left panel you have an import menu and in there you can click the ‘Upload RDF files’. Simply select the graph.jsonld file you exported via the integrations/jsonld_export.py script and GraphDB will do the rest.

The schema can be seen in the export script and a simple SPARQL query to fetch entities looks like

prefix knwler:<https://knwler.com/ontology#>
prefix schema:<https://schema.org/>
SELECT ?name ?type WHERE { ?e a knwler:Entity ; schema:name ?name ; knwler:entityType ?type }
