Hi all,
On behalf of the DPM team, could you please also consider adding:
- "DPM" to ServiceType
the group would like to have an organization name. It has been decided that if there is no organization name, then one can fallback to the group reserver organization name, that can be used for orphan projects.
therefore we suggest:
org.ogf.glue.dpm
What do people think about this?
Stephen already pointed out that a "DPM" _ServiceType_ does not make sense, unless someone else can also implement their own version of "DPM"!
DPM is a _product_ that implements various services (data storage, management and access), each accessible through one or more protocols (SRM, GridFTP, ...).
Thanks for pointing this out, now I read Stephen's comment on that and I actually disagree. I might end up being pedantic, but I think that what a GLUE2 ServiceType_t is about IS identifying a service. Also ARC A-REX is a product that offers job submission interfaces supporting various protocols, and information systems interfaces supporting various standards. Nevertheless it is a service as a whole. Maybe words are used in a bad way, but if we stick to the definition in GFD.147: An abstracted, logical view of actual software components that parti- cipate in the creation of an entity providing one or more functionalities useful in a Grid Environment. [...] If we go to the StorageService definition: An abstracted, logical view of actual software components that parti- cipate in the creation of a storage capability in Grid Environment [...] If we look at the list of ServiceType_t in GFD.147, chapter B.31, you'll se that the third-level names there area all product names. So, if Stephen thinks that we should see dCache and DPM as a single Storage ServiceType_t, I can now say that I don't think we should. If the capabilities are the same, then discovery should be done on capabilities and NOT ServiceType_t IMHO. But this I said in many other various emails. I think the real problem here is that I didn't figure out what this DPM thing is. Nobody sent a description. Nobody sent a link to relevant documentation. If you know about this, please help me understanding this better.
