- WordNet is now at 3.0 on Unix, still 2.1 on Windows. The database from Linux is probably more useful. Interestingly, it's also available in Prolog. The licensing is pretty open these days. I don't think it used to be. That's welcome news.
- Here's something called CoreLex.
- A good overview of the OLIF format.
I think I could do worse for termbase storage in Perl than simply a database schema that mirrors OLIF (at least partly). That could be part of a general OLIF-handling set of modules. OLIF is attractive because it's model-agnostic in terms of how terms are conceptualized, so an OLIF-based module should be able to do something reasonable with essentially any terminological source.
