Permaculture Database

[Bear Kaufmann <bear@ursine-design.com>]

Hi Paul,

I like your thinking. :-)

If you read over the pcplantdb discussions, you'll note that I had a 
great interest in the RDF/OWL/triple model. I'm attaching the start of a 
model that I worked on using Protege (google it if your not fimilar with 
the app). One of the cool things with this is there are some predefined 
ontologies available (ie relating to the earth sciences from NASA, etc).

One of the nice things with Rich's MediaWiki efforts is the parsing of 
the wiki text into both XML and an RDBMS. The guts of the logic requires 
the machine readable relationships, but people also want to read some 
legible text too, which the wiki allows. Maybe theres a way to develop a 
javascript/AJAX tool to help users write a valid relationship.

I hadn't looked at the source/sink idea, but it seems like a good way to 
conceptualize it.

(I'll leave it at that, since I need to sleep).

Cheers,
Bear
