Computing Element
by Laurence Field 03 Jul '07

03 Jul '07

As far as I understand the Computing Element entity is use to encapsulate the relationship between the Computing Service and the Computing Resource. I am not sure if it is good to use an entity to describe this relationship. Can we just define a relationship between the service and the resource directly and remove the Computing Element? Laurence

If you are interested in participating or know of anyone we should contact, please send an email to the Glue Schema mailing list (glue-wg(a)ogf.org) Thanks Laurence

Draft SE Schema
by Laurence Field 12 Jun '07

12 Jun '07

Hi, Please find attached an initial draft of the SE schema. This is an attempt to consolidate all the input which I have received. It is important that we define the main entities and the relationship between those entities as soon as possible, so please focus on that rather than the individual attributes. The attributes should be used as a guide to what the main entities are. I will arrange a phone conference next Thursday 31 May, so that we can dicuss this futher. Thanks, Laurence
