I'd like for foaf:birthday to have a range of cal:Vevent (from the RDF
calendar schema ), theoretically this would allow everyone to supply as
much or little information as is needed/wanted, and provide for richer
integration. However, just like for the W3C date/time profile , it doesn't
seem to be possible - a complete and valid date is needed, month+day is not
If foaf:birthday needs to be this vague (that is, not a complete date), the
only way seems to be specifiying a literal as the range. Not that this
wouldn't be useful, and with some appropriate rules  it should be possible
to do some nice integration and inference, but I imagine rules on literals
will be somewhat hard to make and process.
BTW, there's also some overlap with the BIO vocabulary .
