I was incapable of adding a comment to Jeni's interesting post about RDF predicate Names (markdown-related, my fault), so I'll quickly post it here, as I'm pondering similar things, too.

In her post, Jeni explores the issues around naming RDF terms. The community gathered a couple of experiences and suggestions in the last years, some entry points are:

• Backward and Forward links in RDF just as important
• HasPropertyOf (ESW Wiki)
• RoleNoun (ESW Wiki)

• SUBJECT'(s)? PREDICATE (:|is) OBJECT
• OBJECT is SUBJECT'(s)? PREDICATE
• OBJECT is (the)? PREDICATE of SUBJECT
• SUBJECT has PREDICATE (:)? OBJECT
• (the|a)? PREDICATE(s)? of SUBJECT (is|are) OBJECT ((,|and|&) OBJECT)*

(There are more patterns, for things like tagging and typing, but the examples above are the predicate-related grammar rules).

As soon as you add (has|is|of) to one PREDICATE, you get problems with the other notations, so role-noun seems to be a good fit.

Unfortunately, one (non-trivial) problem remains: People (and Web 2.0 apps) also like 'SUBJECT PREDICATE_VERB OBJECT' (e.g. "likes", "bookmarked", "said", "posted", "is listening to" ...) and I don't have a proper idea how to handle those automatically yet, other than hard-coding support for the typical social media verbs. It could be possible to use wordnet to detect verbs and derive a canonicalized form, and then model those patterns as activities (activity = liking, bookmarking, saying, posting, listening, plus ACTIVITY_PERSON and ACTIVITY_TARGET or somesuch). If anyone has a suggestion, I'd be happy to hear it.
