A lot of was discussed and figured out at the Geo Microformat BOF at O'Reilly's Where 2.0 conference.
See the geo-bof-2005-06-30 minutes/notes.
One of the thoughts that came out of BOF was the idea of location-tagging.
Conclusions on new microformats
The consensus conclusions from the Geo Microformat BOF at Where 2.0 was to define two new microformats to reflect the two kinds of most commonly published geo data.
- adr - for representing / marking-up / publishing address location information. "adr" is simply the hCard "adr" property and all its sub-properties.
- Geo - for representing / marking-up / publishing latitude longitude location information. "geo" is simply the hCard "geo" property and all its sub-properties, with the explicitly specified datum of WGS84.
