[UR-WG] how to publish services information

[john.gordon at stfc.ac.uk]

John, the background discussion during the last meeting was whether there was a place to register these values to lookup what you should use and avoid clashes. It was thought GLUE might provide a place but it seems not. I don't think we want to build the list into the standard but OGF could provide a place on its wiki where a list of known ones is maintained.

Regards,

John

Hi,

I think it may be interesting to know the implementation but I am struggling to see why it is a MUST and also how we would aim for the MUST NOT Clash.

If it is used I agree a project should themselves ensure that no clashes occur but only the infrastructure/project using the standard can define their resource types and ensure this.

can someone help clear this up for me - I may have missed some of the background discussion?

cheers

Dear all,

In reference to the discussion during our last phone meeting I found that GLUE seems not to inforce any standar name. But I also found a rather document (from 2009. You can find it attached to this email) that describe the name usage in WLCG. In particular, concerning the storage:

  *   ImplementationName MUST be published. The format is defined by the implementations, but the names MUST NOT clash. In particular, for WLCG storage services the names to be used are: CASTOR, DPM, StoRM, dCache, BeStMan, xrootd.

  *   ImplementationVersion MUST be published. The format is defined by the implementations.

For OS names there are others directives here (I don not think we need it but while I was looking around for info I found it):

https://wiki.egi.eu/wiki/Operations/HOWTO05

For site names:

https://wiki.egi.eu/wiki/Operations/HOWTO05

Furthermore my understanding is that, at least in EMI, the decision is just to set the EMI release version. Based on that it should be then possible to identify the version of the specific middleware.

Cheers,
Andrea
