Coordinate systems are very complicated, in practice, but we wrote <a href="http://www.nmm.ac.uk/visit/exhibitions/astronomy-photographer-of-the-year/science-of-astrotags/" rel="nofollow">a beginners guide</a> for our astronomy competition. Wikipedia publish celestial coords on its astronomy pages, eg. http://en.wikipedia.org/wiki/Regulus and we're tagging flickr photos via the helpful people at <a href="http://astrometry.net" rel="nofollow">astrometry.net</a>. Oddly enough, we publish RA in degrees, wikipedia uses hours, minutes and seconds. Both are valid units for RA. Whether that's worth adding to HTML? I don't know, but adding a tag that's wedded to a single coordinate system, <a href="http://en.wikipedia.org/wiki/WGS84" rel="nofollow">WGS84 latitude and longitude</a> seems like it would be as short-sighted as restricting dates to the modern Gregorian calendar. Re. BC dates, museums use them online all the time, of course, for antiquities (http://www.nmm.ac.uk/collections/explore/object.cfm?ID=AAA6229). Would it be worth the effort to mark those up as dates in a HTML 5 version of the catalogue record? RA and dec are the celestial equivalents of lat/long, more or less.

But if you've a use case, you should mail the working group.

We've recently been tagging photos with right ascension and declination on flickr, so there might be a case for marking that up in HTML. eg. see the machine tags on http://www.flickr.com/photos/31557673@N05/2955988513/in/pool-astrophoto Re. place/location – could that be generalised to celestial coordinates?
