Hi Sergio,<br><br>Thanks for integrating our requirements into the new GLUE 2.0 spec. What you have in the draft will work for us now. <br><br>The only thing I want to comment on is the ComputingShare&#39;s relationship with the ComputingResource and ComputingService entities. If a ComputingShare is an abstraction of a queue and the ComputingElement is an abstraction of the Batch System, then there should be a direct association between the ComputingShare and the ComputingElement. Having the ComputingShare linked to the ComputingService will introduce a number of replicated instances of the same ComputingShare on all the ComputingServices which is not really necessary. Attached is the diagram again to refresh your memory on what I think it should look like. Anyway, just my 2 cents..
<br><br>Cheers,<br>Gerson<br><br><br><div><span class="gmail_quote">On 6/27/07, <b class="gmail_sendername">Sergio Andreozzi</b> &lt;

Hi everybody,<br><br>we have just uploaded a new draft of the GLUE 2.0 specification.<br><br>Here are the main changes:<br><br>- clarify difference between computing resource and computing element<br>- from Gerson Galang use case: single computing service in front of two
<br>different batch systems<br>- general clean-up<br>- inclusion of first UML Class diagram for Storage Element (description<br>to be added)<br>- added activity entity<br>- promoted share entity as a main concept<br><br>

you can find it in the draft section of GLUE WG document repository:
