Hi folks,
Hmm, interesting subject.
Good to see a nice increase of traffic and discussion on the schema issues. I promise to avoid sending Phase 3 visions of front end system to the list for a while. :-)
A quick something I've been thinking about while wading through posts...I'll reply while wading through the torrent of posts.

deal with in the future, so now would be a great time to explore the
problems of integrations.”
Sean wrote, “.. spelling error, scraping. Basically, we do what google
does. We scan the web pages from other plant database web sites and
archive the information with our own data.”
And then Lawrence asked, “Would it be possible for PIW to have/host
multiple databases, each with different structural needs?…Does this mean
that someone using PIW could request info that we don't have but
USDA does…”
And then Bear said, let there be RDB. hey Bear, isn’t all this what RDB
is used for?
Not everything above.
Actually more about this thread:
[snip]Benifical relationships
It's really about defining a schema for relationships. It uses so called "triples".May I suggest that this simply be "Relationships", which can then include antipathetic/allelpathic information.Indeed this does seem like a good way to simplify the design.
For me this relationship information (+, o and -) is usually the hardest to come by, and most crucial.
Subject:predicate:Object
Even data fields are considered a relationship.
User2300:firstName:Bear
Ladybug:eats:Aphid
If a relationship is bi-directional, we can assume Aphid:isEatenBy:Aphid
For a primer see here: http://xulplanet.com/tutorials/mozsdk/rdfstart.php
I imagine that there probably are a reasonable number of DB's with eats/isEasten type relationships being built by ecologists already.

There are other projects using RDF for biology and botanical purposes. If there is something that's an agreed upon schema for a plant naming system, we might decide to use that spec for that. If other projects use that too, we'd start to speek the same language, and could compare notes (merge/xreference) more easily on things each others domains did or didn't cover.
A man Steph and I meet at the Planetwork meeting said he had interest in the project, and has experience in developing schemas with RDF. He's used Protege to develop with. Find it here: http://protege.stanford.edu/ It's something that I looked at before he mentioned it. I believe it has a collaborate checkin/checkout system to develop with, and editing the schema with data using it doesn't corrupt the info. We might want to talk with him some more. Drawing up this XML DTD/Schema/RDF/etc agnostic description is very good, we could send to to him and see what he thinks.
OK, long day. Going to stop there. :-)
Cheers,
Bear
