Feeding data directly into DataFusion

Suppose I create a new context / data source for RDFs.

Then I use the APIs to feed in a RDF file. Had I gone through
the TRIT, the uris for the predicate and entities are automatically created.

In this case, how do I generate ‘appropriate’ uris for new
predicates/ entities if not going through the TRIT ? Do i generate any random guid to suffice?

    Correct, any valid IRI according to the RDF spec will do. For more details see

    https://www.w3.org/TR/rdf11-primer/

    To properly visualize the relationships in DE/Analyze the system expects CamelCase in IRI fragment, e.g.,

    http://rdf.thomsonreuters.com/relationship/IsSupplierOf

    becomes

    is supplier of

    When using a JDBC connector or delimited import these are automatically created in the data source context based on the ID selected by the user. Context + ID form the subject IRI.

    One caveat here is that if you use a subject IRI that already uniquely identifies another entity in the system, e.g.,

    http://permid.org/1-4295905573

    the system will automatically treat all entities using this subject IRI as one entity, even if they were loaded into different data sources.
