[uf-discuss] uF Discovery?

[Brian Suda]

I'm not avocating something for discivery MUST be built. I am saying
"lets look at how other guys have tried to figure this out, has it
worked, or failed, and what can we learn from that?"

HTML has been successfully broken down into several pieces, CSS for
presentation, HTML for data, and Javascript as yet another layer.

Microformats use HTML as the data layer, XMDP as the decription layer,
but there is no discovery (maybe there doesn't need to be?).

As Luke pointed out:

the advantage of saying what you have available will minumized the
crawl space. I can get one file that tells me everything, or crawl the
entire 40,000 Avon hCard pages to try to get the same thing.

Look at Google Sitemaps, that is a single file that describes the
pages on the site, along with last-update time. This helps to limit
un-needed crawls, bandwidth, time, etc.

This aproach has its downsides as well. Data drift is my biggest concern.
