Thanks Irene for your response. I have a question on getting human readable labels from the results of Change History GraphQL. I see that in SPARQL there is method "afn:localname" to get the local name(prefLabel) of a URI resource(skos:prefLabel ) but it is not the actual human readable label (preferred label) seen in EDG UI. Now my question is that, with GraphQL is there a way to get the human readable labels(as seen in EDG UI) of URI resources(Subject/Predicate/Object) in Change History results(please check the below screenshot)?

No, you can only get the comment of the change, e.g.

To get the labels of the resources (subject, predicate or object), you would need to do a join with the actual data graph, and that is not possible with the current GraphQL endpoint for the team graph. SPARQL would be better for that purpose. The GraphQL endpoint is further limited in that it only renders subject/predicate/object as strings, without further metadata such as the exact datatype.

Also keep in mind that resources may have been deleted, in which case even the main graph wouldn't have a suitable label anymore. That's also why the Change History panel only shows the Turtle source code of what has been changed - as this is the only reliable info that can be derived at that stage.

    For GraphQL, Go to Export -> GraphQL Queries and select “as
    Teamwork Graph” - this is the change history graph.



    For examples on querying change history, see

    David already gave you some examples of SPARL queries. If you go
    to Server Administration -> Available Web Services and then check
    Teamworks SPIN Templates, you will see additional examples that
    have been templated. For example:

    Hi,
       We are looking to generate reports on change history of a
    taxonomy from TopBraid EDG. I see that there is a view(please
    check the attachment) in EDG that shows change history of the
    taxonomy. Now my question is that is there an out of box service
    to fetch those change history details or could you please share
    the SPARQL/GraphQL that is used for the "Change History" view in
    EDG UI? Could some one please help?

    Thanks,
    Sanjeev
