OCCI-monitoring: minor revision available
by Augusto Ciuffoletti 25 Jun '13

25 Jun '13

After some mail exchanges with Andrew and Ralph, there is a minor revision: -) added one session "3 - Addressing simple environments" to give the guidelines and warnings for simplified configurations; -) the transport of measurement data inside the monitoring infrastructure has been rendered with opaque identifiers (String) in metric and input attributes; an adjustment to the definition of scope was deemed appropriate; examples have been fixed to take this into account, and other bugs in the examples are fixed. http://redmine.ogf.org/projects/occi-wg/repository/revisions/monitoring/raw… -- Augusto Ciuffoletti Dipartimento di Informatica Università di Pisa 56100 - Pisa (Italy)

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!

New revision of the Monitoring document available
by Augusto Ciuffoletti 12 Jun '13

12 Jun '13

Hi all, I have just upload in the repository the new revision of the document: http://redmine.ogf.org/projects/occi-wg/repository/revisions/monitoring/raw… Providing a straightforward solution for simple use cases was a topic that emerged as relevant during last call, and this revision relaxes some constraints on the monitoring API in order to meet this intent. Basically, now monitoring mixins may be associated also to Entities not uniquely dedicated to monitoring, thus introducing the possibility to implement monitoring without instantiating specialized entities. The appendix is dedicated to four use cases of increasing complexity that illustrate the above points, the simplest being managed in an extremely simple way. Also regarding examples, I do not use the http rendering but a more readable representation of the involved resources.

OpenNebulaConf2013: Extended keynote lineup and deadline for talk proposals
by Daniel Molina 05 Jun '13

05 Jun '13

Dear all, We have just published an expanded keynote line-up for the OpenNebula Conference 2013 (http://blog.opennebula.org/?p=4707) that includes experts from leading institutions using OpenNebula. The first ever OpenNebula Conference will be held on Sept. 24-26 in Berlin and is intended to serve as a meeting point for OpenNebula cloud users, developers, administrators, builders, integrators and researchers. As OCCI is one of the most used OpenNebula APIs, we think it would very valuable to share how you are using/developing these components on top of OpenNebula. We hope you will consider attending to this conference, there is only 10 days left to submit talk proposals (the deadline is June 15th). We are looking forward to welcoming you personally in Berlin!. -- Join us at OpenNebulaConf2013 <http://opennebulaconf.com/> in Berlin, 24-26 September, 2013 -- Daniel Molina Project Engineer OpenNebula - The Open Source Solution for Data Center Virtualization www.OpenNebula.org | dmolina(a)opennebula.org | @OpenNebula

OCCI API document
by Florian Feldhaus 05 Jun '13

05 Jun '13

Hi Ralf, you said that you wanted to start working on splitting the OCCI HTTP Rendering document into a OCCI API and an OCCI Text rendering document. Did you already do anything in that regard? I have some spare time this week and would be glad to push the work on the OCCI API document. So if you could send me whatever you have, I'd be glad to continue from there. Cheers, Florian

OCCI Comments for todays call
by Florian Feldhaus 28 May '13

28 May '13

Hi, I will be able to work on open OCCI topics next week, especially on separating the text rendering from the OCCI API. Anyone interested to move forward here? If so, how should we coordinate the work? Beside that, I collected some comments on the existing / upcoming documents which I'd like to post here for discussion: # HTTP Rendering Category type-identifier - there is a ambiguity in `SCHEME TERM`. As `SCHEME` is defined as being an `URI` it can match `TERM` as well, but `TERM` has a restriction on lowercase. Replace with `SCHEME '#' TERM` . Even better restrict `SCHEME` to URIs without fragment, e.g. `SCHEME AUTHORITY PATH QUERY` (here `SCHEME` means the URI scheme). PATH must be an absolute path, does it? - link-attribute should be the same as attribute-repr - for link definition, the link-type must be put into quotes - unneccessary semicolon at the end of link example - term should be allowed to contain the same characters as the URI fragment to avoid mapping conflicts (e.g. in OpenStack templates can have the same name but different IDs - thus the numeric ID should be used as term, but is currently forbidden. The unrestricted characters of the URI are (per RFC 3986) `ALPHA / DIGIT / "-" / "." / "_" / "~"` and it would be good to use `ALPHA / DIGIT / "-" / "_" / "~"` for term, as the `.` in schemes contains special meaning in OCCI (domain separator). # OCCI Core - where will the definition of OCCI components go. If we have multiple renderings, the definition of e.g. TERM should be the same for all - for mixins, applies should not be automatically inherited from dependent mixins (e.g. a `small` resource template should have `applies` set to the compute kind even though the resource template mixin may have `applies` set to all infrastructure resources # OCCI Infrastructure - in section 3.2.1 add Network kind as related / applies - in section 3.4.1 add the same actions as for Network - clarify templates. If OS templates are only applicable to Compute kinds, they should have the scheme `http://schemas.ogf.org/occi/infrastructurecompute#os_tpl` and related / applies should point to compute - for resource templates, the related / applies should point to all Infrastructure resources (e.g. storage, network, compute, networkinterface, storagelink) # OCCI API Wishlist for the OCCI API document - move all information common to the different renderings into this document or into OCCI Core (e.g. ABNFs) - use query parameters for attribute=value when triggering an action - pagination - as similar to existing REST APIs as possible (e.g. OpenStack, EC2, CIMI) without too many backwards incompatibility with the current HTTP Rendering document Cheers, Florian

Really quick OpenNebula Cloud APIs survey
by Daniel Molina 27 May '13

27 May '13

Hi all, We, the OpenNebula team, have created a very quick survey (only two questions) to collect information about which cloud API is most widely used, and which cloud API you would like us to enhance or implement (OGF OCCI, AWS, Google Compute, DMTF CIMI, VMware vCloud or OpenStack). It will only take you 10 seconds to complete, your feedback will help us improve the support for the most demanded cloud APIs. https://docs.google.com/forms/d/1QKiYvMjPygaq15i9-OzR9FLOmsCnAKo3xrYVYq5qUJ… Thank you! -- Join us at OpenNebulaConf2013 <http://opennebulaconf.com/> in Berlin, 24-26 September, 2013 -- Daniel Molina Project Engineer OpenNebula - The Open Source Solution for Data Center Virtualization www.OpenNebula.org | dmolina(a)opennebula.org | @OpenNebula
