OCCI & Erlang

Posted January 24th, 2014 in Implementations by admin


erOCCI is a framework for building OCCI like API (similar to rOCCI or pyOCNI), with the following objectives:

  • 100% compliance with OCCI specifications (core and rendering)
  • scalability
  • clear separation between
    • rendering: text/occi, text/plain, application/occi+json, etc.
    • transport: HTTP, etc (XMPP planned)
    • backends: storage (Riak, etc.), “procci” to other APIs
  • small and heavily tested (planned.. but some unit tests already there)

OCCI in OpenNebula

Posted July 18th, 2012 in Implementations by admin


“As open source, community-driven software, OpenNebula is fully committed to standards, ensuring that our users can avoid vendor lock-in. We provided the first reference implementation of the OCCI specification, and have many users and innovative projects that are building solutions around this implementation, so contributing to create an open ecosystem.” – Ignacio m. Llorente. The OCCI implementation in OpenNebula is available through the software ecosystem community web site and is based on the rOCCI framework.

OCCI & CompatibleOne

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.

~okeanos & OCCI

Posted May 23rd, 2012 in Implementations by admin


“Here in GRNET we are developing an API translation proxy in order Synnefo, our IaaS cloud management software to be compatible with OCCI specifications. We believe that this implementation will prove helpful for others to learn more about ~okeanos and its unique features using a widely acceptable, community-lead API.”

The doyouspeakOCCI Compliance Testing Facility,  is a Google App Engine (GAE)-based checking tool for the Open Cloud Computing Interface (OCCI) family of specifications. More specifically, it provides a full compliance test suite for the OCCI Core (GFD.183)OCCI Infrastructure (GFD.184), and OCCI RESTful HTTP Rendering (GFD.185)specifications.

doyouspeakOCCI is written in Python and heavily building on the GAE services, mainly Task QueueURL Fetch, and the webapp Framework.
