[esip-semanticweb] FW: help with marking up WMS/WCS Capability docs? Use triple tags?

[Wilson, Brian D (335G)]

Hello, 

For the telecon at 1 PM, I can describe (and advocate for)
machine or triple tags if that makes sense.

Rather than make slides, we can simply refer to the discussion
of triple tags at flickr.

See http://www.flickr.com/groups/api/discuss/72157594497877875/

John et al,

Machine tags or triple tags are simply tags that have
three parts:  namespace:facet=value.

They were first invented for geotagging (e.g. geo:long=-172.3),
but they can be used more generally for 'faceted' tagging.

See the discussions at Wikipedia and Flickr below:

The best discussion I've read of the power of tagging is
Gene Smith's "Tagging" book:

Hope this helps,

Can you all describe what you mean by 'machine tags'?
