I have put a Dia diagram on the web, you can grab it from my web site

So it should not be directly related to my work, but in the future it
possible can be work together , in terms of MPEG-7 MDS.

I will.

I think that I will add new paradigm, such as <query-paradigm
type="region-query"> and create new plugin that provide a algorithm
which supports two paradigm, for example
<algorithm algorithm-id="s-idf" algirithm-name="Segmented IDF">
        <query-paradigm-list>
                <query-paradigm type="inverted-file" />
                <query-paradigm type="region-query" />
        </query-paradigm-list>
</algorithm>

Finally, I have created a simple MRML frontend based on JSP/Bean which I
will use as my testbed in the future, it can be used to query GIFT
server for now, but not support property sheet yet. Anyway you can try
it out at
