JSON rendering
by Ralf Nyren 21 Jul '11

21 Jul '11

Hi, I missed last weeks IRC session but read the chat-log. I very much agree that an easy-to-parse media type is needed and since I have been talking about a JSON rendering for almost a year now I have made available what I got so far. I used your idea to keep a copy of the Categories in the HTTP header although I render all Categories in JSON as well. Much easier to parse that way for e.g. an AJAX client. Examples do tend to speak best so please find 3 example outputs attached: single_resource.txt - JSON rendering of a single resource instance. Note that the Category header is present. all_resources.txt - JSON rendering of all resource instances, i.e the result of a GET / HTTP/1.1. Note that no Category headers are present here, they are not usable for collections. The compute is linked to the storage using a storagelink so you can see the link rendering etc. discovery.txt - JSON rendering of the discovery interface The occi-py demo is updated with JSON rendering support so please feel free to try it out. Simple specify 'Accept: application/json' in your request to get JSON rendering. JSON parsing for POST/PUT is not yet available so use text/occi or text/plain for creating new resource instances. I used 'application/json' media type for the demo but I guess application/occi+json would be more appropriate. In that case we should probably migrate text/plain to application/occi+text as well... Example commands: curl -i -X POST -H 'accept: application/json' http://www.nyren.net/api/compute/ curl -i -X GET -H 'accept: application/json' http://www.nyren.net/api/ curl -i -X GET -H 'accept: application/json' http://www.nyren.net/api/storage/ curl -i -X GET -H 'accept: application/json' http://www.nyren.net/api/-/ regards, Ralf

Hi, in 2 hours I will give a presentation on "Cloud Standards Interoperability: Status Update on OCCI and CDMI Implementations" at the "Workshop on Science Agency Uses of Clouds and Grids". I attached the slides and if there is feedback within the next 2 hours, I'll try to incorporate it. @Andy: Is it Ok if I use your graphics for the Hadoop scenario? Is the document officially released somewhere? Cheers, Florian

OCCI Implementations
by florian.feldhaus＠tu-dortmund.de 17 Jul '11

17 Jul '11

Hi, tomorrow at 2pm MDT I will give a presentation on "Cloud Standards Interoperability: Status Update on OCCI and CDMI Implementations" based on the Cloud Plugfest last week at the "Workshop on Science Agency Uses of Clouds and Grids". As there were only the R2AD OCCI implementation and our implementation present at the Plugfest, I would like to know which other implementations are currently out there in the wild and what their status is. This is on short notice, but I would be glad if you could provide me the name, current status, license, URL to source code, client/server, test instance and supported OCCI version of the OCCI implementations you are developing or at least know about. I promise to help putting it on the OCCI webpages and other wikis (e.g. Cloud Plugfest Wiki or Wikipedia) if applicable. More information on the "Workshop on Science Agency Uses of Clouds and Grids" can be found here: http://www.ogf.org/SAUCG/ Thank you very much, Florian

OCCI F2F meeting proposal for September
by alexander.papaspyrou＠tu-dortmund.de 15 Jul '11

15 Jul '11

Folks, since the next OGF, which will take place in Lyon, France from September 19-23, 2011, is very packed and things will co-locate with Grid 2011, the EGI Technical Forum 2011, and several other (albeit smaller) events, we will most probably only have time for the official sessions, and not so much time for out-of-band discussion. I therefore would like to suggest a F2F meeting before this event, in the week before. As venue, I can offer rooms at TU Dortmund University, which is easy to reach via Düsseldorf International Airport (DUS). I guess a two-day meeting would be good to have enough time to discuss. If there is need for more time, this is possible as well. Please indicate your preference for the week at http://www.doodle.com/z6kiqmmbsww755hw Best, Alexander

OCCI text, json...
by Edmonds, AndrewX 14 Jul '11

14 Jul '11

During today's conf I said I had an ANTLR grammar that read in the OCCI text format and converted it to a possibly suitable OCCI JSON format (Ralf and I had sync'ed on this JSON structure some months ago). You can get the code for this here: https://github.com/dizz/occi-grammar/tree/master/occi-antlr-json Note that the grammar is an old one and is not accurate. You can expect this [1][2] sort of output from it.

Your Questions...
by Andy Edmonds 12 Jul '11

12 Jul '11

Hey Cyril, I saw some of your comments [1] [2] on twitter about OCCI. It'd be great if you could elaborate on them on the list as everyone here really values useful and constructive comments and critique. BTW: you might have been viewing older OCCI specs. The latest published are here [3].

Virtual meeting for OCCI-WG at OGF 32?
by Alan Sill 12 Jul '11

12 Jul '11

Dear OCCI working group, As you know, we strongly encourage attendance at OGF events to get our community to overlap with each other in person as much as possible and to encourage progress on milestones and work items. Having people attend the events assures that they will be active methods of making progress in our community. It si also almost the only method that we have to ensure that the IP agreement has been signed for each session by all participants in a discussion at an event. That having been said, at this meeting only I happen to plan to bring a videoconferencing system and can make access available to the OCCI working group through a desktop to H.323 system bridge that operates on resources that can be accessed for free. I could, if desired, put together a video meeting that would allow you to meet remotely for this event. Phone bridging to this system is also available. If this is of interest, please let me know and I will explore the options. Thanks, Alan Alan Sill, Ph.D Senior Scientist, High Performance Computing Center Adjunct Professor of Physics, TTU Vice President of Standards, Open Grid Forum ==================================================================== : Alan Sill, Texas Tech University Office: Drane 162, MS 4-1167 : : e-mail: Alan.Sill(a)ttu.edu ph. 806-742-4350 fax 806-742-4358 : ====================================================================

Re: [occi-wg] [ogf-board] OCCI Wikipedia entry
by Craig Lee 11 Jul '11

11 Jul '11

Can we get more of the implementations and associated URLs listed? There is the Implementations link in the References, but it would be preferable to have them all listed in the table. Also, how about a graphic and associated text that gives a high-level view of how OCCI works? (Like the attached png.) The "Web Hosting Journal" and "OCCI and SNIA" links in the References are stale. --Craig On 7/11/11 7:48 AM, Alan Sill wrote: > The OCCI WG has updated its Wikipedia page, as linked below.
