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

Andre, What is the proper way for the GLUE WG to manage files under http://schemas.ogf.org/glue/? We want to publish new JSON schemas. Thanks, 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.

Progress on LDAP schema
by Florido Paganelli 18 Jun '14

18 Jun '14

Hi all, Yesterday I tested the changes mandated by the new version of the LDAP document in a test environment and I didn't see any issue. I didn't see any bad error in slapd logs, and the objects that were affected by changes are published as expected. I attach the latest schema and kindly ask Maria and Paul to test the impact on their products: GLUE20.schema.20140508 A list of diffs between the current distributed version of the schema (2.0rc5) against the new version (2.0rc6) that is included in this email: distro2.0rc5_diff_2.0rc6.changes I suggest you check them with some nice editor that colors things up so you can easily spot differences. I pushed the source schemas in my git-hub area temporarily, if we're fine with that I will push it to the official repos: https://github.com/floridop/LDAPWIP I would say that we should put recommendations in the release notes that I added in the README files on git-hub. I didn't do it yet, but the issues I can imagine we should add are the following: 1) ABSTRACT classes to be in sync with XML realisation: Objects like Entity, Resource, Share, Policy have been declared ABSTRACT to be in sync with the XML schema. This means these cannot be instantiated as is; only their specialization can (i.e. Computing- Storage- or others like Benchmark etc.) are objects that can be published. 2) Boolean type changed to DirectoryString This means that if the boolean values that are mandatory in the schema are not defined, the information providers MUST publish them and MUST present the value "undefinedvalue"; GFD.147 Appendix B.17. These are: ExecutionEnvironment.ConnectivityIn ExecutionEnvironment.ConnectivityOut If you spot any problem, let me know.

Fwd: Re: New ServiceType
by Florido Paganelli 18 Jun '14

18 Jun '14

Hi all, I was requested to share the conversation I had with Maria wrt new ServiceTypes, see below -------- Original Message -------- Subject: Re: [glue-wg] New ServiceType Date: Tue, 17 Jun 2014 10:47:00 +0200 From: Florido Paganelli <florido.paganelli(a)hep.lu.se> To: Maria Alandes Pradillo <Maria.Alandes.Pradillo(a)cern.ch> Uhm, actually I've been to fast... I don't understand these names, and I cannot advice the group to accept them. The reason is, the domain names called dpm.org and storm.org don't seem related to the services you mentioned. The org in front is not cosmetics, maybe you should also read section 2 of the document I sent. The prefix is the reverse DNS name of the organization maintaining the service/product. Inspired by the reference emails you sent, I'd rather suggest the following: for DPM: ch.cern.dpm.storage for StoRM: it.infn.storm.storage If you don't want to bind these to the mentioned organization, an option could be to use glue2 special prefixes: org.ogf.glue.dpm.storage org.ogf.glue.storm.storage Let me know what you think before I bounce this back to the GLUE2 workgroup.
