Quick description of an old TimBL post related to Ajar, using nanotation (which turns this post into an RDF data source) [1]:On Tue, 2015-02-24 at 11:43 -0500, Kingsley Idehen wrote:It looks like that on the surface, but it simply boils down to:1.

It sounds like the approach I stumbled onto while looking for a sensible way to make a heavy client for displaying RDF. In theory it could provide great power and simplicity, but I can't say I've worked through the initial complexity to prove the point. Regards, --Paul

the local name, and the URI formed using the hash,
refer to arbitrary things. When a semantic web
document gives information about something, and uses a
URI formed from the name of a different document,
like foo.rdf#bar, then that's an invitation to look
up the document, if you want more information
about. I'd like people to use them more, and I think we
need to develop algorithms which for deciding when
to follow Semantic Web links as a function of what
we are looking for. -- TimBL

rdfs:comment """
To play with semantic web links, I made a toy
semantic web browser, Tabulator. Toy, because it is hacked up in
Javascript (a change from my usual Python) to
experiment with these ideas. It is AJAR - Asynchronous Javascript
and RDF. I started off with Jim Ley's RDF Parser
and added a little data store. The store understands the mimimal
OWL ([inverse] functional properties, sameAs) to
smush nodes representing the same thing together, so it doesn't
matter if people use many different URIs for the
same thing, which of course they can. It has a simple index and
supports simple query. The API is more or less the
one which cwm and had been tending toward in python.
