<div dir="ltr"><div>Dear DMers,
</div><div><br></div><div>We are requesting comments for the IVOA Provenance Data Model. The proposed recommendation is available through its dedicated RFC web page and attached to this email:
</div><div><br></div><div><a href="http://wiki.ivoa.net/twiki/bin/view/IVOA/ProvenanceRFC">http://wiki.ivoa.net/twiki/bin/view/IVOA/ProvenanceRFC</a></div><div><br></div><div>Compared to last year's PR, the different classes and relations were refined, keeping the initial base, and explaining further the connections between classes.
</div><div><br></div><div>There are points that are still being discussed within the group and for which your comments would be particularly appreciated:
</div><ul><li><span style="line-height:1.45">Specialized Entities: we propose in the document to have entities dedicated to Configuration, Description and Context for an activity. This also means that those entities have a primary usage, and are a priori not considered as Main Entities (like Data or Documents), even though they can be derived from those.</span></li></ul><ul><li><span style="line-height:1.45">Handling of input parameters for an activity: the possibility to manipulate such parameters directly and independently from main entities has been included, but another view would be to just manipulate those parameters in the same way as the main entities.</span></li></ul><div>We plan to organize a splinter session at the next interop in College Park to discuss those points and the model, and hope to see you there !
</div><div><br></div><div>Best Regards,
</div><div><br></div><div>Mathieu Servillat for the IVOA Provenance Working Group
