Hi Holger A simple use case of viewing corpus topics is if the tagset is imported into a datagraph. How are the values of the content and corresponding tag shown on a form.
E.g. Content1 corpus:topic conceptA Content 1 corpus:topic conceptB For example, if I have a form in the datagraph that references the URL of Content1. How can the above corpus:topic triples be used to generate an inference in a form to list all existing tags for Concent1 (e.g. content A and B) ? The only way I've been able to do this is to construct new instances of a class with new properties e.g. something like Content1 a corpus:Document ; corpus:hasTopic Content A ; corpus:hasTopic Content B . But this just leads to a lot of information bloat. On the fly inferences are preferred.
