Seems that attributes are going to be easier to parse. So here's a reformatted (thanks Jim!) version of my XML document:
The concern at this point is whether each visual component needs such a great range of values. An alternative: for color, use "warm" and "cool" rather than the HSB values. The advantage would be that only the strongest visual components would be stored, established by a threshold over which they are significantly perceptible. The disadvantage would be that each visual component is still evaluated only once over an entire image. My worry is that this is somewhat shortsighted given how dynamic each visual component can be within a single image. But it doesn't seem to be any worse than the first version. So I'll write it up.

On the plus side, it seems like once this attribute tagging is done, it would be really trivial to pipe them into an automatic slideshow (or whatever), based on this data.
So what will that look like? I'd want to see two things: a processed piece of media created from random, dynamically tagged photos -- and another created by hand, so to speak, with the photos and tagging all done by you before they go in the system.
attributes are much better than your previous version, btw.

I used elements originally for structural symmetry and ease of editing/extension. Though attributes are cleaner looking and seem to be just as easy to use. So the switch is made.
At the moment, I'm creating the metadata for individual images manually, though I expect to be able to automate the metadata creation process for most of the visual components.
The hand-crafted version is in development with an ETA of Wednesday.
