<p>Hi Markus , <br>
</p>
<p>The Prov-W3C is providing the general framework , and the
concepts. In practice, for each application domain one needs to
bring more information about the usage , rules, specificities. <br>
</p>
<p>The Activity Class for instance is a place holder, to gather
info about a task but not precise enough <br>
</p>
<p>most of what we need to describe astronomical programs /tasks
are not defined in W3C .<span class="secno"> See for insance <br>

<pre wrap="">Hi Mireille,
Here's another topic from the RFC responses (keeping topics apart to
try and have focussed discussions):

<pre wrap="">I've posted the following to the Wiki, but I thought having it on the
list might be more conducive to discussions, so here's what I my
thoughts were while reviewing this.
TL;DR: let's only have the core model in 1.0. We can always add
extensions in 1.1.

<pre wrap="">we need the ActivityDescription class and Parameter class to be able to
search for some specific processing type on the data.
Activity is only the process launched for the computation.
It does not hold the details of the methods , because those details are
factorised in the ActivityDescription class.

You mean "Find me all source extractions being done on the images of
this data collection"? That *does* sound like a fairly basic thing to
want to do, yes, and from what I see in the current Activity model, it
would, indeed, seem to be impossible just with what's there.
I'm sure the W3C has a plan for this -- do you know what it is? Can't
we just follow them or is there a use case we have they don't?
