Cues for tools namespace prefix in JSON response #57

Closed twagoo closed 6 months ago

twagoo commented 3 years ago

This is needed to resolve https://github.com/clarin-eric/component-registry-front-end/issues/154

Response from server for this test component (front end uses JSON rendering in request/response):

Namespace is omitted by backend! (e.g. "@inclusive-or":"grp")

Since there is no fixed schema constraining the element names, we need to know the namespace.

Note that DisplayPriority in the same namespace is handled correctly (with a special mapping??)

Looks like we might be able to use a solution similar to the example at https://www.intertech.com/jaxb-tutorial-customized-namespace-prefixes-example-using-namespaceprefixmapper/

Some helpful documentation in https://eclipse-ee4j.github.io/jersey.github.io/documentation/1.19.1/user-guide.html

This was indeed fixed in 2020 (a95063ce51062af650f1080e897ed6a7335ed14c)
