Thanks for your comments posted in [1]. The new version is now:

You will find below the detailed changes addressing your comments:

Rephrase as:
"At the time of writing, most work done in this area does not use semantic-based
technologies mainly because of the differences between the multimedia and the web
communities and their underlying standardization organizations."

done as suggested

The sentence was not deleted but rephrased as:
"The reader should be warned, however, that large scale, industrial strength
image annotation is notoriously complex."

done, the code snippet is detailed as well as the XML namespaces explained.
References to RDF Primer and OWL Guide provided.

Change to:
"Section 5.1 provides an example solution for this use case using semantic-web

This comment meets a previous one formulated by Mike. All the use case
description has been rephrased and there is not anymore reference to SW
technology in the description.

As the VRA guru, we trust you (Jacco aggree too :-)
The sentence has been rephrased to:
"All the elements of VRA Core have either direct mappings to comparable fields in
Dublin Core or are defined as specializations of one or more DC elements."

True, done.

We will try to update the separate living web pages on a regular basis, either
with our personal find, or most probably by answering specific request, comments,
suggestions, new tools annoucements, etc ...
The following sentence has been added:
"Any comments, suggestions or new tools annoucements will be added to this
separate document."

done as suggested.

The word "solution" has been most of time replaced in the document.

There is now a reference.

> Are the rights for the image(s) cleared?

Yes for the images from the personal use case, the e-culture use case, and the
NASA use case. For the TV archive use case, it was no possible to be sure to not
have copyright issue, the image has thus been removed.
