Hi Jerzy,
David Newman <[email protected]> in Southampton handles the RDF and
SPARQL support.
David: I've attached a couple of main threads to this email so you can
have a look (as well as the thread below) , as I don't believe you are
on this list.
Cheers,
Jits

Thanks. I was not aware of RDF and SPARQL support in MyExperiment.
You should be aware that rdf.myexperiment.org is still under development
and so is not yet supported as an official part of myexperiment. If you
find any bugs in it, please send them to [email protected]
Using the SPARQL queries should not affect the main www.myexperiment.org
site as the queries are run on a cached snapshot of the main site. That
does mean though, that if you cannot debug your queries by altering
attributes of workflows on the main site.

I could do it. Downloading all the workflows is not be a problem (I do
It using SPARQL). But where should I put the translated workflows?
I tried translate the workkflows using the code in CVS, and it worked (I
got the Dataflow Object out of scuflModel Object) but I had problems for
doing anything with I. For example, I did not know how to save it
because importing the libraries we used at the workshop in Manchester
resulted in errors.

The sparql command I use is:

For T2 workflows.
To make it automatic I prepare a POST query and send it to
http://rdf.myexperiment.org/sparql and I get XML file with links to all
the workflows
