I would also suggest you look at the ISO 13249-5:2001 (SQL/MM Still
Image) standard [1] which defines a SQL data type and SQL operators for
image processing.  This might suggest ideas for the kind of operators
you might want to define with the XQuery extensibility mechanism (e.g.
XQuery functions) on an image XML data type.

I believe there is work going on assessing the use of XQuery with MPEG-7
data at the University of Fribourg in Switzerland. Try Nastaran Fatemi
[nastaran.fatemi@epfl.ch] as a point of contact.

[Dear Mustafa, I'm forwarding your question to www-ql@w3.org , the forum
for XQuery's discussion, as this is an interesting use case.]

 

In general, I think your question could be replied as: operationally,
there would be the need for a wrapper (and, although this is a very
interesting application, I don't think anybody tried to tackle this
yet). 

The second point is the expressive power of XQuery wrt the MPEG-7 DDLs,
i.e. what kind of "meaningful" queries can be supported using XQuery on
DDLs. That's also a very interesting use case, worth mentioning in the
public.

 

XQuery folks, any idea / related work? This could be a potentially nice
application of XQuery in multimedia.

Hi to everybody,
I would like to ask a very short question about the XQuery/XPath

supporting of the XMLDB.


Could you please inform me or direct me for supporting?

That is; 

I would like to learn if I can perform complex similarity query
operations
on a XML (infact MPEG-7 DDLs) form Audio/Visual meta-data using
XQuery/XPath?

Forexample:

1) "List of all the programmes from my favourite radio channel,
    along with their broadcast time, and the first two minutes but
music"

or

2) "List of all the speaking that speaks a specific person before
another
    specific person"

Does XML Query language XQery/XPath, directly support/provide such kind
of
queries?

Best Regards,
