A few weeks back, I went to see Neil Young at the Academy. This represents quite a few firsts for me: although I’ve loved his stuff for years, this is the first time that I have seen Neil Young live, and likewise Crazy Horse. It’s also the first gig that I have been to for quite a while. I have never got over the sense of excitement of live music and this has only been increased by its rarity. I was definately looking forward to it.
Although it appears fairly innocuous, the last
commit
to tawny-owl seems momentus to me. While I still need to go through the
spec line-by-line, and the code needs some clean up, this commit
essentially represents the completion of the tawny.owl namespace; the
addition of data properties and data types was the last part of the spec
that I have to fulfil.
Tawny-OWL (n.d.a) is a
library which enables the programmatic construction of OWL
(n.d.b) One of the
limitations with tawny as it stands is that it did not implement
numeric, semantics free identifiers
(n.d.c) tawny builds
identifiers from the clojure symbols used to describe the class. So, in
my pizza ontology, for
instance, PizzaTopping gets an iri ending in PizzaTopping. Semantics
free identifiers have some significant advantages; the principle one is
that the establish an identity for an object which can persist even if
the properties (the labels for instance) change, as I have described
previously (n.d.d)

Our original intention with Greycite (n.d.a) was to build a tool which can provide bibliographic metadata for any URL, to support my own kcite referencing tool (n.d.b) While it still fulfils this function, it also turns out to be a useful, general-purpose tool for investigating the metadata in various web pages. And this reveals some interesting results. We discovered a nice example of this recently while adding RIS support.
