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!

JSON Rendering proposal, rev 2
by Ralf Nyren 01 Mar '12

01 Mar '12

Hi all, I finally got some time to work on the JSON Rendering. The document now include a formal description of the JSON formats, almost complete (I hope). I have tried to incorporate much of the feedback received so far. Short summary: - Use separate media-types for rendering the different payload contents. Inspired from Florians references to the CDMI spec. - Try to make the single-instance format more lightweight and not duplicating any information available through the discovery interface. Thanks Jamie. - Use the "marker" concept from OpenStack for pagination as suggested by Andy. - "range" and "default" attribute properties as requested by Florian. PDF attached and latex sources committed to gridforge. Comments welcome. Unfortunately I will not be able to attend the plugfest but if you plan a session on discussing the JSON rendering please let me know and I'll call in. regards, Ralf

Sessions at OGF 34
by florian.feldhaus＠tu-dortmund.de 27 Feb '12

27 Feb '12

OGF 34 is approaching and I finally found the time to request a BoF session to start a new Cloud Interoperability group. I would like to invite all of you and everyone you know who might be interested to join the session and help start the CI-WG. Besides that, I would be glad to help organize some OCCI sessions at OGF 34. Who will be able to attend? What could be the topics for the sessions? The summary for the CI-WG session is: Interoperability in Cloud Computing is of increasing importance. Several cloud standards have emerged in recent years and implementations for them are starting to show up. Customers and providers interested in using the standards are requiring best-practise documents for using or implementing the different standards and also rely on information how they can combine multiple standards. This BoF session will present current challenges in Cloud Interoperability and aims at collecting ideas, approaches and experience in this area as starting point for a new Cloud Interoperability Working Group. This group shall also serve as a forum for engagement with other standards organizations and exploration of interoperability of OGF cloud standards work, and of software based on that work, with standards and software from other organizations. The agenda for the CI-WG session is: * Introduction to cloud standardization * Overview of current challenges in cloud interoperability * Collecting ideas, approaches and experience in this area as starting point for a new Cloud Interoperability Working Group. * Survey of existing plug-fests and other interoperability points of contact * Collaboration with other organizations Cheers, Florian

JSON Rendering
by Feldhaus, Florian 24 Feb '12

24 Feb '12

Hi all, I'm continuing with the work on the JSON rendering (I attached the latest version). I'm currently reviewing the rendering of entities. I was wondering, if we could use "Collection" for rendering single entities as well. On the other hand, we might as well drop the Collection completely and just use an array of entity renderings. I would prefer using the term entities, as the rendering is then similar to the rendering of the categories (with "kinds" and "mixing"). What do you think? e.g. instead of using { "collection": [ { "kind: { … }, "mixing": { … }, "actions": { … }, "attributes": { … } }, { "kind: { … }, "mixing": { … }, "actions": { … }, "attributes": { … } } ] } we could use either: { "entities": [ { "kind: { … }, "mixing": { … }, "actions": { … }, "attributes": { … } }, { "kind: { … }, "mixing": { … }, "actions": { … }, "attributes": { … } } ] } or just: [ { "kind: { … }, "mixing": { … }, "actions": { … }, "attributes": { … } }, { "kind: { … }, "mixing": { … }, "actions": { … }, "attributes": { … } } ] Cheers, Florian ------------------------------------------------------------------------------- GWDG - Gesellschaft für wissenschaftliche Datenverarbeitung mbH Göttingen Am Fassberg 11, 37077 Göttingen Fon: 0551 39-20364 Fax: 0551 201-2150 E-Mail: florian.feldhaus(a)gwdg.de WWW: www.gwdg.de<http://www.gwdg.de> ----------------------------------------------------------------------------------- Geschäftsführer: Prof. Dr. Ramin Yahyapour Aufsichtsratsvorsitzender: Prof. Dr. Christian Griesinger Sitz der Gesellschaft: Göttingen Registergericht: Göttingen Handelsregister-Nr.

Thought you would be interested in the following link. Topic: ... several members of the OpenStack community have announced their collaboration to build TryStack, a free sandbox for those interested in exploring and testing the open source cloud operating system. Link: http://www.computerweekly.com/blogs/open-source-insider/2012/02/rackspace-d… Note also we have our own FutureGrid sandbox: https://portal.futuregrid.org/project/176 -- accounts are available for anyone who wants to try a cloud standards-related experiment or integration. Can anyone summarize the status of the OpenStack implementation work for OCCI? Alan

OCCI header information for JSON
by Gary Mazz 10 Feb '12

10 Feb '12

Hi Thank you for the interesting discussion on meta-data for the json rendering. It was suggested OCCI meta-data should be defined as HTTP headers for the JSON and XML forms. We should seriously examine adverse outcomes of modifying well established protocols. Placing OCCI meta-data in the http header area ignores best design practices, specifically compartmentalization. We would not consider placing OCCI headers in IP or TCP protocol header space, we should not consider impacting the HTTP transport data space. Although precedence has been set, additional meta-data in http headers for alternative forms of OCCI data exponentially increases the cost burden on product testing and validation. In my experience attempting to release a CDMI javascript library, I ran into a few security issues surrounding browser behavior. It seems the prominent browsers execute a Cross Origin Resource Sharing (CORS) protocol when a custom header is defined for any http request. CORS places a additional protocol demands on OCCI servers and OCCI clients that normally would not need to support CORS. I would strongly suggest to avoid the complexities associated with OCCI meta-data in the http message header area and select an alternative approach placing OCCI meta-data in the http message body. b/r gary mazzaferro

Submitter's message The next three meetings before the plugfest will be devoted to test matrix development. The test matrix will be maintained in the plugfest Wiki. Wiki accounts will be setup for registered participants before the start of tomorrow's meeting. Note: Some of you may receive similar and/or duplicate messages regarding plugest activities. This is because of the independent distribution lists that used to facilitate this effort. I'm looking into ways to streamline this in the future. -- Mr. Thomas Mancuso ----------------- Event Title: Cloud Plugfest Planning Meeting Date: Tuesday, 07 February 2012, 08:00am - 09:00am PT Description US – Toll Free Access - 1-866-439-4480 US - Toll Access - 1-212-786-7191 Participant PIN Code - 16651018# (or 87763154#) International Access Numbers: https://images.magnetmail.net/images/clients/ARKCS/attach/Arkadin_Internati… WebEx - http://snia.webex.com Meeting number: 793 124 513 Meeting password: cloud2012 Host key: 473844 View Details : https://members.snia.org/apps/org/workgroup/cloudtwg/event.php?event_id=456… ----------------- Agenda Agenda: Participant Update (Tom) Local logistics (Florian, Mike) Test Matrix (Krishna)   Owner: Mr. Thomas Mancuso Group: TWG: Cloud Storage Sharing: This event is shared with the Storage Networking Industry Association (General Membership) group.
