Hi all, We are pleased to announce you that our paper "A Model-Driven Tool Chain for OCCI" was accepted to the 25th International Conference on Cooperative Information Systems (CoopIS), Oct 2017, Rhodes, Greece. Abstract: Open Cloud Computing Interface (OCCI) is the only open standard for managing any kinds of cloud resources, e.g., Infrastructure as a Service, Platform as a Service, and Software as a Service. However, no model-driven tooling exists to assist OCCI users in designing, editing, validating, generating, and managing OCCI artifacts (i.e., extensions that represent specific application domains and configurations that define the running systems). In this paper, we propose the first model-driven tool chain for OCCI called OCCIware Studio. This tool chain is based on a metamodel defining the static semantics for the OCCI standard in Ecore and OCL. OCCIware Studio provides OCCI users facilities for designing, editing, validating, generating, and managing OCCI artifacts. We detail the tooled process to define an OCCI extension. In addition, we show how the cloud user can leverage the generated tooling for this extension to create his own OCCI configurations and manage them in the cloud. We illustrate our paper with the OCCI infrastructure extension proposed to define OCCI-compliant compute, network, and storage resources. A preprint version of the paper is available online at https://hal.inria.fr/hal-01583165/document. Source code of OCCIware Studio is available at https://github.com/occiware/OCCI-Studio. Binary distributions for Linux, Windows, MacOS are available at https://github.com/occiware/OCCI-Studio/releases. Your comments are welcome.
