It would be, yes :]

From a quick search on Wikipedia, I found out that PDF[1] indeed does support 
RDF[2] via XMP[3] embedded in the PDF file.

The problem here really does seem to be where ConTeXt comes into play.

I suppose it would be enough for ConTeXt if it would support embedding RDF via 
XMP into PDF.

How this semantic data would get to ConTeXt would get there should be a 
problem for the user and/or the editor (s)he uses.

* From the editor side, on the KDE SC[4] desktop I imagine getting Kile[5] to 
import RDF from NEPOMUK[6] and Akonadi[7] databases would be possible.

* Another possibility would be for ConTeXt to support importing RDF directly 
from iCal and vCard, FoaF[8], SIOC[9] etc.

...in both cases though I think it would be enough if ConTeXt could simply 
include or refer to an external XML file that includes the needed RDF data and 
generate a PDF from that. IMHO as a non/idiot coder on top of that additional 
modules could be written to e.g. automatically tag the PDF with NEPOMUK tags.

As far as the PDF end user side is concerned, I think we needn't worry. I've 
talked to some guys from the W3C and they are very much working in the 
direction of semantic data driving pretty much everything on the web and on 
the desktop. As already said, KDE is also very strong here and other big 
desktops (including MacOS and Windows) are trying to catch up as well. From 
what I gathered, both the semantic desktop side and the semantic web[10] seem 
to have a sure future and we should see widespread use in the next two years 
or so.

Cheers,
Matija

P.S. Is there a nicer wording then "(s)he" for referencing persona in unisex 
gender (other then "one")?
