Aside from publishing in several semantic output
formats, we should also add meta-data right into the
content.
The formats to use for this are RDFa and/or
Microformats. I’m not sure whether we should make a
choice and pick one (in which case RDFa is the best
option, although not supported as much certainly the
most rich and extensible) or just add both (as long as
there are no conflicts).
Using this various tools will be able to use this
information, e.g. a Calendar plugin in the browser
could offer the user to add a calendar event based on
hCalendar metadata in the content.
