For a couple of days already I have been ruminating over putting down an ontology for Tracker (GitHub), my personal issue tracker, somewhere, when it hit me all of a sudden, that I already have a perfect place for this: my Personalist app, about which I’ve written here.

Tracker’s ontology is now hosted here, at personalist.org.

The thing with software ontologies is that they shift (have to!) slightly over time, as new requirements come in, or existing ones change, and in sync with that, as our understanding of the domain, and of the application which models it, changes. This is why Personalist is the perfect place, because it can capture this changing understanding across time.
