Max,
This is what I like best about SWIG. We are moving rather quickly
nowadays and think very alike.
We are working on an Atom OWL ontology and we have been using similar
notions to extend the relationships for several of our constructs in a
way we have more semantic breadcrumbs to help us describe/understand a
wide range of predicates otherwise unknown to us.
First [1] we are using it to describe different content types.
In N3 :entry1 :content "<b>blah</b>"^:html translates to:
:entry1 :content [ :html "<b>blah</b>" ] in Turtle and fully expanded means:
:entry :content [ :body "<b>blah</b>"^^:html ].
Second, we are using this style to model extension in the XML space. For
example:
In Atom/XML:
<a:entry>
<s:when>Today</s:when>
</a:entry>
:entry s:when "Today" .
s:when rdf:subPropertyOf :ExtensionElement ;
:localName "when" ;
:namespace "http://example.org/s" .
As you can see the notion that (a, x, c), (x rdfs:subProperty b).
