Group Leadership
by Andre Merzky 25 Oct '12

25 Oct '12

Hi GLUEs, two OGFs ago, JP and Shiraz have been proposed and accepted as new chairs for the GLUE-WG, and in fact have taken on that responsibility on a practical level. The only reason that this change was not implemented on the OGF bookkeeping level was that there was no feedback from the existing group chairs. We would like to rectify that situation. I would thus like to ask the existing GLUE chairs (Balazs, Laurence, Sergio) about their commitment to continue working as active chairs of the group, and also would like to again ask the group members at large if there are any concerns about JP and Shiraz as GLUE-WG chairs. It would be great if feedback would be provided within the next 10 days. Best regards, Andre. -- Nothing is really difficult...

Outcomes from the OGF36 meeting
by Shiraz Memon 25 Oct '12

25 Oct '12

Dear WG, As planned during the OGF36 we have had intense discussions on the outstanding issues. Thanks a lot to the presenters who (despite of unpleasing network issues) have substantially contributed and made the sessions interesting. The slides have already been uploaded on our wiki, and can be accessed from the link below: http://redmine.ogf.org/dmsf/glue-wg?folder_id=40 Outcomes: * XML rendering: It has been decided to use the "Flat" rendering, however whether to use choices for references and/or nested elements is yet to be decided. For that a separate phone meeting will be arranged. * LDAP Rendering with(out) DIT: a dedicated meeting will be arranged to move closer to the decision of incorporating DIT (if agreed) in the rendering document. * Initiated a new task to realise a JSON Rendering of the GLUE 2 entities. EMI and FutureGrid are currently the only stakeholders. I and Warren will kick-start this activity in the coming days, off course anyone on the group is welcome to contribute.

ogf36 - flat or combined XSD
by david.meredith＠stfc.ac.uk 17 Oct '12

17 Oct '12

Hi everyone, I am not sure what the outcome of the OGF36 was regarding the choice between Flat or Combined GLUE2 XSD (a solely nested approach does not seem feasible given the number of requirements for flat). I think we agreed to go away for a week or so and give it some thought and then vote. Therefore, to help make a final decision, please find attached the OGF presentation which outlines the choices, pros and cons (and at the link below).

by Florido Paganelli 15 Oct '12

15 Oct '12

Hi all, I was trying to access GLUE2 github area to create the enumerations repositories and create a LDAP experimental branch. Does anyone know how it works to get write access? I don't see anything to request it... Thanks, -- Florido Paganelli Lund University - Particle Physics ARC Middleware EMI Project

JSON rendering
by Warren Smith 05 Oct '12

05 Oct '12

Before I forget, I thought I'd send out a couple example documents for the JSON rendering that I'm using for a distributed testbed called FutureGrid. I'm advocating that we switch to JSON for XSEDE, but XSEDE has a fair amount of momentum with XML from TeraGrid and a couple of the new tools we're deploying, so we'll see. Similar to the TeraGrid XML rendering, the style of this rendring is "flat". There are two documents because sensitive information (ComputingActivities that have user names) is placed in a separate document that can be protected while the non-sensitive information is available to anyone in the other document. I think there was at least one other project that created their own JSON rendering. Is mine in the same ballpark as yours? Are there folks interested in defining an official JSON rendering? Warren

xml rendering discussion
by david.meredith＠stfc.ac.uk 04 Oct '12

04 Oct '12

Hi all, Please find attached a pdf that I hope summarises the flat vs nested XML renderings and their pros/cons. The pdf also includes some other (less important) style choices for the flat rendering (i.e. whether to use Grouping elements, BaseType attributes or both). I have tried to include all recent comments.

flat xml rendering
by david.meredith＠stfc.ac.uk 04 Oct '12

04 Oct '12

Hi all, Following OGF 35 I have produced an updated draft of the XSD: http://tools.ngs.ac.uk/ngstools/glue2proposal/flat.zip This rendering has a 'flat' style and includes the global <Entities> element bag with abstract elements/substitution groups. There are a few choices that still need to be addressed which are highlighted with TODO annotations (please do a search on 'TODO' in glue2_2.xsd). A sample instance document is also provided (glue2_2SampleDoc1.xml). For the purposes of demonstration, there is also a sample XSD (sampleGlue2_2Extension.xsd) that imports the glue2_2.xsd to define new service and endpoint element types. This shows how future profiles could extend the glue XSD in order to define new sub-type specialisations (also see the sample instance doc, sampleGlue2_2ExtensionDoc.xml). I guess the next step is to do another telephone conf to agree/disagree. If possible, i would prefer to do this before spending too much effort on updating the Word doc.
