Broken links on the OCCI WG website
by Boris Parak 20 Dec '16

Hello everyone, I noticed that the OCCI WG website has been updated and OCCI 1.2 docs were published. However, links on the Specification page [1] seem to be broken. Is there someone with credentials who could have a look at it? [1] http://occi-wg.org/about/specification/ Thank you. Cheers, Boris

Paper: Are REST APIs for Cloud Computing Well-Designed? An Exploratory Study
by Sill, Alan 24 Nov '16

24 Nov '16

Dear OCCI working group, Hope those of you in the US celebrating Thanksgiving are having a pleasant time with friends and family. For those who are interested, the paper at the link below is useful reading. https://hal.archives-ouvertes.fr/hal-01352738/document >From the conclusions and future work section: "For our first contribution, we reviewed the literature extensively and compiled a catalog of 73 best practices in the design of REST APIs making APIs more understandable and reusable. We believe that our catalog is exhaustive at the time of writing. We hope that this catalog can be used by other researchers to study some quality characteristics of REST APIs as well as practitioners when designing, implementing, and assessing their own REST APIs. For our second contribution, we evaluated and compared the design of the REST APIs using best practices from the literature and showed that Google Cloud follows 66% (48/73), OpenStack follows 62% (45/73), and OCCI 1.2 follows 56% (41/73) of the best practices."

How the Serverless Framework is Reshaping AWS Lambda - The New Stack
by Sill, Alan 09 Sep '16

09 Sep '16

Thought you would be interested in the article at the following link. It has some interesting points vis-a-vis OCCI: note that at least half of the effort goes into managing the underlying infrastructure, according to experience developing the 1.0 beta. Topic: The Serverless framework garnered massive interest after the project was posted to Hacker News earlier this year. Serverless is an open-source project, so community feedback has been essential from the start, shaping the foundational building blocks for the v1.0 beta release. Link: http://thenewstack.io/how-serverless-is-reshaping-aws-lambda/ Thoughts welcome. Alan

EC consultation on cloud computing
by Jensen, Jens (STFC,RAL,SC) 06 Sep '16

06 Sep '16

For those of you/us/you in Europe (and don't mention the B-word), this may be of interest: https://ec.europa.eu/digital-single-market/en/news/consultation-cloud-compu… Not sure how much weight is given to this sort of input but we might even put something together on behalf of OGF or OCCI (use of open standards, etc. - should I send it off to ISO as well?) For example, in the associated data protection document (co-authored by a few well known suspects), Challenge 4 mentions the standards. PS. Apropos stuff, don't forget the plugfest later this month: www.cloudplugfest.org which has an OCCI theme as well. PPS. I've been on leave but aim to catch up on OGF docs ASAP.

Thought you would be interested in the following link. Has anyone in the group been to, or is anyone interested in going to and representing OCCi at these conferences? Topic: About REST Fest Our objective is to give people interested in REST, Hypermedia APIs, crafting web service APIs, or any related topics a chance to get together in an informal setting to share ideas, trade stories, and show examples of current work.

pOCCI test suite updates
by Jean Parpaillon 27 Jun '16

27 Jun '16

Hi Boris, all, I've pushed several fixes/changes into a branch of pOCCI that you may be interested in merging into the main branch. These changes are available in: https://github.com/jeanparpaillon/pOCCI/tree/erocci Changes: * accepts 201 and 200 when authorized: some tests previously acceped only 200 or 201 * works with endpoints rendering full url for categories collections (ie /compute or http://example.org/compute) * allow use of a proxy with 'proxy' option in pOCCI.cfg file (used for requests registration then benchmarking) Regards, -- Jean Parpaillon -- Open Source Consultant Director @ OW2 Consortium OCCIware Strategic Orientation Committee Chairman Research Engineer @ Inria -- Phone: +33 6 30 10 92 86 im: jean.parpaillon(a)gmail.com skype: jean.parpaillon linkedin: http://www.linkedin.com/in/jeanparpaillon/en

Hi all, this is a reminder about the special session entitled "*Experiences with OCCI*" that we want to schedule during Closer 2016 (Rome, April 23-25 2016). The deadline for paper submission expires on February 10. If you want to report and discuss about an adoption, or propose a new application, you still have more than three weeks to put it on paper and send to us. All relevant infos are now on Closer site in a dedicated page <http://closer.scitevents.org/OCCI.aspx>, or in our flier <https://dl.dropboxusercontent.com/u/1327309/Closer_OCCI_2016.pdf>.

OCCI entities ids
by Jean Parpaillon 28 Apr '16

28 Apr '16

Hi, We've had a discussion during last OCCI-wg session in Roma about the way to specify entity ids. As specified in current documents, entity ids can be specified in different ways _at the same time_ at creation time and implementations behaviour is not specified. I suppose we should consider either removing different ways to specify ids either specify implementation behaviour. Here are the different ways the can be specified: * JSON rendering: * 'id' attribute in JSON document * 'occi.core.id' attribute in the 'attributes' property of the JSON document * HTTP protocol: * PUT request: url of the request + rendering specific (see above) * POST request: rendering specific In general, for renderings where core attributes are rendered differently from others (id, source, target, etc), it is not specified how to deal with attributes being set twice. A suggestion will follow in a next e-mail. For me, the most important being to avoid ambiguities as to improve implementations interoperability.

OGF activites at UCC 2016 and 2017 conferences
by Sill, Alan 07 Apr '16

07 Apr '16

Hi all, I am co-chair for the Utility and Cloud Computing (UCC) 2016 program committee in December of this year and will be general chair for the one we are co-hosting (UCC 2017) the following year in Austin, Texas USA. UCC 2016 will be in Shanghai and UCC 2018 (the year after the one we are hosting in Austin) will most likely be in Zurich. There are good possibilities to build in good cooperation between OGF and these conferences, and perhaps to co-host workshops, plugfests or data-oriented activities also with this and the usually associated Big Data Science, Engineering and Applications (BDSEA) conferences that are frequently co-located with the UCC conferences. Jus wanted to poll the group here on this topic, and pass on the Call for Papers and related information about the web sites. If we want to do plugfests or have any associated activities, now is the time to speak up in order to get these included in the plans and to get started on preparations. Please speak up if you are interested and/or can help. http://computing.derby.ac.uk/ucc2016/ http://computing.derby.ac.uk/bdsea2016/ Alan
