VOTE by 8/1: GLUE 2.1 for describing cloud resources?
by JP Navarro 01 Aug '14

01 Aug '14

GLUE Working Group: We have been discussing two options for using the GLUE schema to describe cloud services. You may review these options here: - http://redmine.ogf.org/dmsf_files/13294?download= By August 1, please vote for one of the following options: 1) Use GLUE 2.0 with a Community Practice Profile that details how to describe cloud infrastructure using the existing 2.0 entities 2) Develop GLUE 2.1 adding new Cloud Computing entities (would be 100% backward compatible with GLUE 2.0 for non-Cloud entities) For reference, a preliminary GLUE 2.1 Specification is available here: - http://www.ogf.org/pipermail/glue-wg/2014-January/001527.html Regards, JP

Redmine or forge?
by Salvatore Pinto 31 Jul '14

31 Jul '14

Hi all, I saw around that some reference for GLUE documents points to GridForge (https://forge.ogf.org/sf/docman/do/listDocuments/projects.glue-wg/docman.ro…) eg. the one in https://github.com/OGF-GLUE/LDAP , while here in the mailing list we refer usually to http://redmine.ogf.org/dmsf/glue-wg . What is the difference between the two? Which one has the latest info? Cheers, Salvatore. -- Salvatore Pinto Cloud Technologist, EGI.eu e-mail: salvatore.pinto(a)egi.eu skype: salvatore.pinto0 Science Park 140, Amsterdam, The Netherlands

Notes: GLUE WG sessions at OGF 41
by JP Navarro 28 Jul '14

28 Jul '14

Notes from July 16-17, 2014, OGF 41 GLUE WG sessions. LDAP rendering -------------- ACTION 1: JP/Shiraz will call for a working group e-mail vote by July 25 to release LDAP rendering document for public comment. Changes should be submitted as change tracked word updates. NOTE: Given that the call for vote will not go out till July 23, WG chairs will extend the vote thru July 31st. JSON rendering -------------- ACTION 1: Warren will cleanup document and schema (including dates) and send draft to working group for review and e-mail vote on releasing for public comment. If working group approves release for public comment: ACTION 2: Shiraz will export draft to word, enable change tracking, and apply OGF formatting for release for public comment. Public comment announcement will include details of existing and planned implementations. Discussed creating a wiki page with implementor details pointing to github, mentioning relevant tools, and other guidelines to help implementors. Agreed to publish to schema.ogf.org, for example: http://schemas.ogf.org/glue/2013/05/spec_2.0_r1/Activity.json The schema path date will be the month of release for public comment. In appendix where JSON schema documents are included, precede each schema document with the URL to the above schema.ogf.org publishing location. Describing Clouds ----------------- ACTION 1: Shiraz/JP will call for an e-mail vote on using GLUE 2.1 for interoperable clouds. ACTION 2: Salvatore will include new Horizon 2020 requirements in the draft 2.1 specification. ACTION 3: Salvatore will call for an e-mail vote to approve GLUE 2.1 for release for public comment, and request for non-disruptive additions/corrections to be applied before releasing for public comment. We plan to release GLUE 2.1 with cloud support for public comment around December and (possible) OGF 43 in London. Discussed whether XSEDE produce a 2.0 community profile? Opinions: fine either way. Perhaps a community practice isn't necessary if XSEDE's implementation is public (which it will be). Enumerations ------------ We discussed managing separate enumeration files for each enumeration and distributing a shell script to download and concatenate all of them. This will eliminate the overhead of having to maintained a merged file. Andrew (BES/JSDL) will submit some requested enumerations. Will also submit a request for a new enumeration type coprocessor that we will probably want to include in GlUE 2.1. He wants us to figure out what entity it belongs in within the abstract information model. Discussed requesting for volunteers thru e-mail list to work on missing enumerations. Miscellaneous ------------- Peter Solagna is replacing Salvatore in EGI GLUE effort. There is an OGF 42 in London, September 8-13. There may be an OGF 43 also in London, the second week in December. If anyone has a preference for a face-to-face in September OGF 42 or possible December OGF 43, please let the group know. Regards, JP

associations in JSON rendering (RE: NOTES: GLUE WG teleconference, Tuesday, July 1, 2014)
by Warren Smith 01 Jul '14

01 Jul '14

David, Shiraz, and I emailed a bit and regarding 4) below, I think we're happy with Option 4. This seems a good middle ground between interoperability (the consumer knows that certain association directions will always be there) and flexibility (a project can also represent an association in the opposite direction). Does that work for everyone? Warren ________________________________________ From: glue-wg-bounces(a)ogf.org [glue-wg-bounces(a)ogf.org] on behalf of Navarro, John-Paul F.
