Hi,
Grimoires, the OMII-UK service discovery implementation, currently
supports GLUE 1.3, but we wish to update this to support an XML schema
rendering of GLUE2. Given that there isn't currently an up-to-date XML
schema for GLUE2 from the WG, we were wondering how best to proceed.
We're aware that there is an XML schema developed by TeraGrid - would
this be an appropriate way forward until one is developed within the WG?
Any advice gratefully received!
Best Regards,
Steve Crouch

Dear colleagues,
Finally I have put together all major design decisions made during the LDAP
implementation process and created a document with them. It is now open to
your comments and suggestions.

Hi,
We are looking at GLUE2 XML realizations, i.e., the official but a
little obsolete one
(http://schemas.ogf.org/glue/2008/05/spec_2.0_d42_r01) and the
NorduGrid one (http://svn.nordugrid.org/trac/nordugrid/browser/arc1/trunk/doc/tech_doc/inf….
(We are also aware of the TeraGrid GLUE2 XML schema.)
The official schema and the NorduGrid schema are similar. Both define
only a single XML element: <Domains>. And all the other entities are
defined as XML types instead of elements. Thus they can be included in
<Domains> but can never stand on their own. Therefore, under this
design, in order to update a single piece of information, for
instance, Domains/AdminDomain/Services/ComputingService/RunningJobs,
one has to re-publish the whole AdminDomain.
Our observation is that the current design of GLUE2 XML schema is not
optimised for updating part of the information. Is this because
updating part of the information is never an intended usage pattern of
GLUE? A validity attribute is defined for each entity. We assume the
intended usage pattern of GLUE information model (including the XML
realization) is to PERIODICALLY publish ALL the information once the
validity period expires. Are we correct? Many thanks!
