Trifolium repens -> interaction[symbiotic] -> Rhizobium leguminosarumo What's the difference between a quality/attribute and aI'd say nitrogen fixing is an attribute, but
relationship? For example is nitrogen fixing a relationship or an
attribute? What about alleopathic (sp?) properties?
habitat types, plant uses are relationships.
Then again, from the perspective of those little N-fixing bacteria, it might look more like a habitat type, or a plant use...
N-fixing at least for some legumes depends on the presence of the appropriately 'related' (ahem... ;-) bacteria in the soil - and vice versa...if a plant that has the *potential* to relate with/support/provide habitat for n-fixing bacteria is put where they aren't present, it won't have that 'attribute'...so I'd say it's not an attribute.
Trifolium repens -> common_name[English] -> White Dutch Clover
Trifolium repens -> interaction[symbiotic] -> Rhizobium trifolii (source: http://www.rsnz.org/publish/nzjar/2002/017.php)
Rhizobium -> fixes[atmospheric] -> nitrogen
Rhizobium -> habitat -> aerobic
Rhizobium -> morphology[shape] -> rod
Esh, what a tangled web of relationships...inference engine anyone?
Probably want to put Legume between the clover and the Rhizobium (many -> legume, legume -> rhizo) But man, googling for data, there's been so much research done on all these features. It's a shame there already isn't a machine readable (RDF?) abstract form for this data.
Attributes would *only* be things that have no significant interdependency on something external to the plant - an intrinsic property of the plant.BTW, faceted searches seem like they'd work great for taxonomic identification...
So most of the taxonomic stuff, if I understand it right, would be attributes (e.g. the descriptive taxonomies used to classify plants - 'clusters of three leaves', 'five-petaled orange flower', 'three evenly spaced branchings per stem', etc. etc.)
Find a trait of the plant (that you understand or can observe), flower color = red...
OK, all the red flowers come up...
It's got a tree habit...
OK, getting close, only 30 matches...
Pea-shaped flower...
2 matches. Locust...(racking my own limited DB... :-P )
Rich, if you have time, would you mind taking a look at:
