I doubt that practitioners are interested in a RDF, OWL specification of the
task models. I don't know how many interactive application developers use
ontologies in their work.

Of course it is possible to do it but I am not sure about the  concrete
added value in a similar exercise. XML descriptions in general are easier to
understand and manipulate than the others even if they have some limitations
in terms of expressiveness.

Hi Dave,

thanks for forwarding the comment by Yan.

Here I guess we can see the different views people have on a specification
again. XML-based languages in MBUID have a long tradition and are well
established in this community.
Also in practice XML-based languages for e.g., infotainment systems are
specified in such a way (e.g., OEM-XML, AbstractHMI).
We had many talks about the different possibilities for using a specific
notation. People have arguments for paper-based informal specifications and
people have arguments for (more) formal specifications.
It depends on the user (group) you are asking. Often the least common
denominator is a XML-based language. But in the end it doesn't matter which
way you go (XML or RDF/OWL) because you will always need powerful tools to
support people.

What do the others think about the comment of Yan?
