How to retrieve user-defined RDF-URIs in OSLC query results

Stephan Leutenmayr (23●8) | asked Jan 23 '17, 10:54 a.m.

The query results of an OSLC query do include the custom attributes that are defined for an artefact type. However, the query results do not use the RDF-URIs that I defined in the project properties for those custom attributes. Rather, arbitrary URIs are used, e.g. https://hostname/rm/types/_Otp_YceDEeagedFUHCigAA#4647618b-7d09-4f82-8d1e-04db2bb621a9

Only if I retrieve a single artefact using its rdf:about URI, my user defined RDF-URIs are used, e.g.
<j.0:country rdf:resource="https://hostname/rm/country#a-country-name"/>

Is it possible to have the user defined RDF-URI included in the OSLC query results?

Thank you in advance.

The OSLC standard does not define any means of translating these implementation URIs into some more logical user-provided URI. This would rather be a tool specific capability base on how it supports extensibility.

Dear Jim,

thank you for your answer. This clarifies the issue somewhat. I understand that the OSLC standard does not define a translation between these URIs. However, I do not understand why the OSLC implementation of IBM on the one hand provides the user defined URIs when retrieving a single artefact but does not provide the user defined URIs when querying for artefacts. As this is the Jazz forum of IBM, I was hoping to learn on the specific implementation of IBM.

Kind regards

Stephan

One can ask DNG for the Schema for a Component of ProjectArea for a given Configuration. That XML document is the Rosetta Stone which allows one to translate from the Component's custom type URIs to the inscrutable, internal ones used by Jazz.

Either with a bit of XSLT or with some RDF reasoning, one can map from one form of the URIs to the other by following the owl:sameAs relationship.

It's all about the answers!
