Dasein Cloud
by Thijs Metsch 23 Jun '13

23 Jun '13

Hi, Just to inform you that there is a cool project going on called Dasein-Cloud. http://dasein-cloud.sourceforge.net/ On the website it reads: Dasein Cloud is an Open Source Java API made available by enStratus Networks LLC under the terms of the Apache License 2.0. This API specifies cloud-independent interfaces for enabling an application to access resources across multiple clouds. If you are interested have a look - and it might be great to implement OCCI in their someday!

Re: [occi-wg] Request for clarification: Are multiple lines allowed?

I believe that not is allowed. The newlines in this case are merely for readability purposes. Thijs?

Request for clarification: Are multiple lines allowed?
by Vincenzo Ciaschini 25 Feb '13

25 Feb '13

Dear members of the occi-wg, In the federated clouds working group, we are having a discussion about the interpretation of the HTTP rendering of the OCCI standard (document GFD.185, http://ogf.org/documents/GFD.185.pdf) Our doubt is the following. In several examples in the document, for examples in section 3.4, page 8 or in section 3.5.1, page 20, we see Category: elements laid out in multiple lines. Our doubt is if this examples are normative, and thus it is acceptable to write them in multiple lines, or if this had been done just for readability, and the answers from the OCCI server should actually lay out a Category in a single line. In the interest of interoperability among our different implementations, can you please clarify this point? Thanks in advance, On behalf of the Federated Clouds Working Group

Cloud interoperability session at CLOSER 2013 (remind)
by Augusto Ciuffoletti 14 Feb '13

14 Feb '13

Dear all, during next CLOSER conference there will be a special session dedicated to Cloud Interoperability: the topic is rapidly gaining momentum, and I considered as appropriate to find a place where to gather results and proposals, to have a snapshot of what's happening on the field. The members of this community have an established interest and competence in the field, not restricted to the OCCI initiative: I hope that the many groups and individuals that participate in the task of cloud interoperability find the time and resources to contribute to the event with a paper reporting their results. You find the details about the CLOSER conference at http://closer .scitevents.org/, and infos about the Cloud Interoperability session are at http://closer.scitevents.org/CI.aspx. The conference will be held in Aachen (Germany) 8-10 May, and the deadline for papers submission is *March 1st*. Thank you for your attention Augusto -- Augusto Ciuffoletti Dipartimento di Informatica Università di Pisa 56100 - Pisa (Italy)

OCCI Monitoring API
by Augusto Ciuffoletti 08 Feb '13

08 Feb '13

Dear all, following the extremely fruitful meeting in Zurich, here is the revision of the proposed document. A few anticipations about the content: - the concepts are always the same: abstraction from short-lived details using mixins, extract/aggregate/publish pipe for the measurements - the syntax is different: I tried to make it simpler and more powerful: only 2 kinds in the model (one resource and one link), but the monitoring infrastructure may be hierarchical from 0 to n levels - a section about conformance levels has been added: the monitoring API is optional, so we need to define a level 0 to avoid confusion. The other two levels corresponds to the capability of creating user mixins (level 2) or not (level 1) - there is a detailed example of a simple case using an HTTP rendering You can directly interact with the LaTeX document if you like, though the pdf is attached as well. The LaTeX document is available on a specific collaboration platform: www.writeLatex.com. It is possible to update the document, but I ask you to follow these simple instruction, to avoid to lose the control of the document. If you want to add a note, please use the \rem command, whose usage is described by the following example: \rem{Augusto Ciuffoletti}{My comment goes here} placed near the sentence you want to comment. A footnote will be generated ("My comment goes here"), signed with your id ("Augusto Ciuffoletti"). You can access the document here https://www.writelatex.com/26835vgbcrcwithout authentication needed. The browser window is divided into two parts: on one side you can edit the source, on the other you see the updated document view. You can also download the pdf or a zip of the current state of the document. There is no "revision history", so it is impossible to "undo" a change.

JSON Rendering update
by Feldhaus, Florian 07 Feb '13

07 Feb '13

Hi all, I updated the JSON Rendering document to be in line with the latest updates to Core. Also I harmonized some wording and improved the formatting a bit. The content of the document is considered to be mature enough for submission, but the format of the document needs improvements beforehand. The document has been merged into the master branch of the Git repository to be finalized there for submission. Cheers, Florian
