Thijs, Thanks for the document, looks to be coming along well. I'm wondering whether there has been any thought or discussion about using WADL as a machine protocol description format for the OCCI REST interface?

OCCI - SNIA coordination
by Mark A. Carlson 15 Jul '09

15 Jul '09

Not sure if folks have already seen this, but this is the reference model that the SNIA has come up with for describing the CDMI interface. It would be great if folks that are working on the storage aspects of OCCI could read and understand how the storage industry is approaching this. I will try and make next week's call (I didn't realize the time was moved up this week) if anyone has questions about this model. Thanks, -- mark

Status of OCCI - Welcome to all newcomers!
by Thijs Metsch 15 Jul '09

15 Jul '09

Hi @all, As of today we got more than 170 members on the mailing-list and 30 members for our gridforge project. First of all thank you all and welcome to OCCI! With this email I want to welcome everybody who recently joined and give a short update of what we are currently up to! The group started as Cloud API earlier this year (March) and got a constant grow from there on. In the beginning we actively discuss the charter and the very basics of our RESTful API. At OGF26 we presented our progress and we try to present a first implementable draft by OGF27 later on this year. So we will be one of the first standardized APIs in the Cloud area. If you want to know who is involved (and maybe add your own name) have a look at our Memberslist in the Wiki (Can be found via http://www.occi-wg.org) Currently we are writing up the documents - that is the reason why the discussions on the mailing-list have stalled a little bit. For a current status do not hesitate to look at our gridforge page and have a look in the SVN. If you want to get involved have a look at http://www.occi-wg.org. There you will find links to our Meeting-materials, Press releases, Presentations, collaboration efforts with other groups etc. Our weekly teleconference call is scheduled every Wednesday @4pm CET. If you have questions, ideas or want a more detailed status update feel free to join! I am looking forward to hear you there! You can find all the details howto connect in the Wiki!

Priorities of the requirements
by Thijs Metsch 09 Jul '09

09 Jul '09

Hi, I started working on the document which will describe the use cases and requirements. Therefore I need to add priorities to each of the requirement we have. I would lik to ask you to have a look at our Use Cases and then at our requirements and then edit the 'Priority' field. The requirements Wiki page can be found here: http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/Requirements Valid values would be either High, Medium or Low. I will start soon adding my thoughts on this issue. But feel free to edit the Wiki page yourself! We will also discuss this on our next concall!

OCCI Latest Draft
by Sam Johnston 07 Jul '09

07 Jul '09

Morning all, I've been doing some more work on the draft over the weekend and today as I hope to have it in good condition in time for the various cloud interop events next week. It's finally starting to take shape now that extensions (e.g. state machines), attributes and registries (e.g. HTTP status codes) have been added, even if they're a long way from finished. The OCCI Core profile is generic and can be used with any resource, while OCCI Infrastructure defines compute, network and storage nouns (with attributes that are designed to be both extensible and trivially mapped to txt, json and xml formats) as well as extensions for relevant functionality like state machines. Anyway the GridForge subversion repository just blew up and my local version doesn't build any more so given it's after 4am already I'm going to call it a day and send what I have so far by mail (attached). The master's DocBook v5 but there's HTML, XML-FO and PDF renderings too... I'll fix the subversion repository tomorrow so others can get in on the action. If you do plan to contribute though, please bear in mind that I am making personal contributions available under CC-BY-SA in addition to the standard OGF terms which I consider far too restrictive. I'd very much rather other editors follow my example so as the spec is not inextricably bound to any single organisation, as is customary for other cloud APIs (e.g. GoGrid, Sun Cloud API). Thanks, Sam

Opinion Poll: IaaS or PaaS ?
by Gary Mazz 03 Jul '09

03 Jul '09

Sam Johnston's timely IaaS feature matrix brings up some interesting issues, one in particular, what are the specific features that can be included in an IaaS. Many of the IaaS provider are also providing one or more operating systems while other are providing closer to bare metal. Is the OS part of the Infrastructure or part of the Platform ? The question is: " Do operating systems belong in IaaS or PaaS. " Please lets us know you opinion -cheers gary mazz
