[OHM] Linked Data

Fri Apr 10 22:44:12 UTC 2015

I wouldn't go so far as to say that "RDF is not end-user friendly". I think
that's on the UI/UX failures up to this point. The subject + predicate +
object model can be displayed and UI elements designed in a way that makes
the representation of relationships easy to document. Autofills with short
notations, for instance, solve a lot of the ambiguities of deciding "hmm
same_as vs. is_instance_of". I guess what I'm trying to say is that the
unfriendliness of RDF to an end-user isn't necessarily or primarily because
of the model for assertions but the UIs that have been attempted thus far
by non-designers. Also, I think Albin is on the right track by
investigating the triple tag/machine tag format (
https://en.wikipedia.org/wiki/Tag_(metadata)#Triple_tags) for expressing
complex relationships.

Cheers!
