[esip-semanticweb] [ESIP-AQ] help with marking up WMS/WCS Capability docs?

[Wilson, Brian D (335G)]

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'?
