The Geospatial Semantic Weblog has a quick howto on mixing RDF/A with GeoRSS in a webpage.


<span about="http://highearthorbit.com" property="georss:point">42.4266 -83.4931</span>

The premise of RDF/A is the ability to embed metadata without having to repeat the information in the normal expression and the XML expression. By using GeoRSS the property of the information being displayed in the HTML page can also be semantically linked to any other metadata in the page referencing http://highearthorbit.com.

For a counter-example, look at the Microformats: geo that requires duplicating the data, but also allows for a different display of the actual data.

    ajturner, geo absolutely does NOT require duplicating the data, but I can certainly understand one could easily come to that conclusion given the only inline example in the specification that uses abbr. Thanks for pointing that out. There is an example of a simple geo without any data duplication on the hCard examples page: GEO, but I realize that is not nearly obvious enough. I have fixed the geo examples section itself to show both types of examples.

    Thanks,

    Thanks for fixing the example and pointing out my mis-statement of the geo Microformat. A benefit of the Microformat I didn’t point out is that by using the class attribute, you get to semantically markup the data and style the tag, whereas with the RDF/A you have a to have multiple attributes to markup and then for styling. An example of how Microformats are meant to be quickly & easily incorporated into existing sites.
