[Update – 2016/12/20] Fixed permanent links to the PDF documents.
Stackforge is the place where all OpenStack related projects can find a common home. The OpenStack OCCI implementation has now moved to stackforge infrastructure and can now be found here.
The ICCLab presented on the latest developments (PDF) in the Open Cloud Computing Interface at the Future Internet Assembly in Dublin. The session was organised by Cloud4SOA and the main theme was MultiCloud. In this regard, OCCI figures in many projects striving from this including EGI FedCloud, CompatibleOne and BonFire. In the presentation some future points of work that will be carried out in Mobile Cloud Networking, which took the audience’s interest.

The aim of this workshop, held at Cloud Interoperability Week, is to set out some short and medium term objectives towards the long-term goal of interoperable cloud solutions. The event will bring together the diverse communities that will need to co-operate to understand how best to standardise different approaches.
Presentations will focus on (but are not limited to):
- Applications of standards in industry and in open-source projects
- Provenance and availability of cloud standards
- Practical use of cloud standards and frameworks
- Importance of interoperability
- Interworking between standards and popular framework solutions
- Tools for conformance and performance testing
- Future trends and priorities
To submit a proposal, please fill in the presentation submission form.
ETSI, OCEAN Project, OGF, OW2 and SNIA invite you to their first joint Cloud Interoperability Week, 18th – 20 Sept, co-hosted with the EGI and SDC conferences.
If you want to have your say fill in the Cloud Standards Implementation Survey.
The event will provide an insight into the current state of Cloud Standards implementations and use cases. It continues the series of Cloud Plugfests aimed at promoting interoperability efforts on cloud standards-based software, services, frameworks, products and projects and will be combined with a workshop and demonstrations.
The Cloud Interoperability Week will be co-located with the EGI Technical Forum and OGF39 at the Hotel Melia Castilla, in Madrid, Spain, 18th – 20 September. Registration is free and will be open shortly to public and private companies involved in cloud solutions based on recognised standards.

At the EGI Technical Forum in Prague, the FedCloud task force presented their progress on bringing various standards together in order to compose a federated cloud within Europe. The presentation ended with an impressive live demonstration of that very work.
During the presentation eight different sites participated offering a set of standardised interfaces. Upon those sites cloud resources were allocated on very different infrastructure management frameworks but unified through the OCCI API. In one part of the demonstration 5 virtual machines were provisioned simultaneously, using OCCI, in Cyprus, Germany (2), Sweden and the Czech Republic. This was followed by a similar demonstration of provisioning storage and accessing that storage using CDMI through the same cloud resource providers.
When: Friday 12th October
Where: Open World Forum http://www.openworldforum.org/en
What: Cloud computing is perceived as a new IT domain where interoperability, portability and reversibility sound like impossible issues to solve. This session will demonstrate how open and interoperable clouds are possible in the face of service provider lock-in. The audience will be able to evaluate the gaps and the real solutions to make open cloud, i.e. a cloud of freedom of choice, a reality.
As a follow up of last year’s session “Open Cloud in Europe”, we have the pleasure to organize a whole Open World Forum track dedicated to open cloud and open standards, and would like to invite you to participate in this session to provide feedback from open cloud projects and on the usage of open standards. The goal is to support Standards Development Organisations with your experience and insight: we want this meeting to be a forum where those who get their “hands dirty”, who are experienced in creating and deploying cloud applications, can present and question usage of and requirements for open standards.
We are looking for experienced developers who have faced issues when:
- using non-standard APIs,
- moving from non-standard/de-facto APIs/libraries to standard implementations,
- failing to use cloud standards,
- achieving interoperability between implementations / standards,
- achieving portability between implementations (e.g. there is no VM image standard… or is there?),
- trying to avoid implementation / provider lock-in,
- working on automation.
So if you can answer positively at least one of the following questions, you are the kind of candidate we would be delighted to welcome on this track.
- Are you implementing standards?
- Are you interfacing to standards?
- Are you working on standards specifications?
- Do you want to bring issues and/or highlight deficiencies regarding standardisation?
- Do you want to demonstrate your implementation/solution using standardised APIs?
- Are you working on a “framework project” (OpenStack, OpenNebula, CloudStack, Eucalyptus, CompatibleOne, …) and like to share your thoughts on which role they play with respect to standards development and adoption?
- Do you work on multiple clouds? Do you deal with many interfaces?
- Do you face issues moving your application from one provider to another?
Your proposal should be sent by the 10th of September 2012 at the latest, email@example.com
Your participation will be confirmed in until 25th of September 2012.
Looking forward to meeting you,
Alan Sill and Florian Feldhaus, Andrew Edmonds, Andre Merzky, Jean-Pierre Laisné

CompatibleOne provides an implementation of the OCCI server in C. You can also see all the OCCI-based services and interfaces that CompatibleOne supports. CompatibleOne has a clear focus on the need of interoperability in the Cloud and so uses OCCI.
News from our OCCI loving CompatibleOne friends:
For our next Hands On Session, CompatibleOne Team has the great honour to announce the particpation of Billy Cox, Cloud Strategy Director for Intel Software & Services Group. Billy will share with us his perspectives about Cloud Computing and the role of Cloud Service Broker (see Billy Cox’s Bio below)
This Hands On Session will be held over 2 days (13th & 14th of June) in Institut Telecom Mines ParisTech, 46, rue Barrault – 75013 Paris (room C128).
This session will be the opportunity to answer all the questions you may have concerning usage of CompatibleOne. You will be able to to manipulate CompatibleOne platform with the help and support of the developers themselves. And naturally these sessions will be interactive and will take place in real conditions i.e. in the cloud.
The detailed agenda can be found here. Note that due to international participation, all presentations and discussions will be in English. The hands On Session is free of charge but the number of seats is limited. Please confirm your participation ASAP on doodle.
We look forward at meeting you there, CompatibleOne Team.
A team in Engineering (partially funded by Venus-C) have released a tool, ovf4one, which provides an OCCI interface that accepts OVF and provisions resources through the OpenNebula OCA interface. It is implemented in Java and implements the OCCI specifications and uses OVF messages and OpenNebula as backend.
From a technical perspective, ovf4one is an OCCI to OCA gateway, translating RESTful OCCI calls into OCA RESTful calls and the OVF XML message is translated into OpenNebula VM templates. This project has been realised as part of Venus-C EU project.
