Thomas, Thanks. That was a great description of why I tend to think of authorities as about a person, place, event, etc. Whether an authority structure started out with a strong effort to record information about the thing it was describing or evolved to include it, there is no denying that most do at this point in our history. I, too, am not advocating for catalogers to create triples for all knowledge in the universe. Yet, if we model our data in a way that allows us to create entities that the rest of the word can understand and link to, we will be able to harvest/link to data they generate. Together (with some creativity, strong semantics, and more open data pipelines) we can fill in the gaps. Sincerely, Steven Forgive any typos, sent while on the run. > On Aug 26, 2015, at 6:18 PM, Thomas Berger <[log in to unmask]> wrote: > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > >> Am 26.08.2015 um 22:48 schrieb Karen Coyle: >> >> What I'm getting at is that the reason that we struggle with tradition > al >> authorities in RDF is that they do not have the qualities that an RDF >> graph about a person might have.
