OCCIware Factsheet
• 72 man month, 5,6m€ budget, sponsored by French ministry of Industry over 2015-2018• 3 academics, 5 companies, 2 associations• To lower Cloud Computing adoption costs and break up barriers between its various implementations, layers, domains
- Especially Data Center, deployment, Big Data, Linked Data
• By bringing to OGF's Open Cloud Computing Interface (OCCI) the power of formal languages and model driven engineering (MDE)

OCCIware Outputs• A formal, model-driven platform to manage any Cloud resource
- Formal model of OCCI, on MIT's Alloy – Inria & TSP- OCCIware Studio, on Eclipse EMF & Sirius – Obeo- OCCIware@Runtime & console, using Models@Runtime and erocci – ActiveEon & Scalair- Deploy@OCCIware - ActiveEon & UJF
• 4 Use cases- Data Center as a Service / IaaS, on Scalair infrastructure- Big Data / HPC, on ActiveEon ProActive HPC platform- Linked Open Data, on Ozwillo app store's Datacore – Pôle Numérique & Open Wide- Deployment interoperability, on Linagora & ActiveEon's
• Open Source (OW2, Eclipse) and standardization (OGF) with help from a 10-strong international Scientific Orientation Committee

OCCI demo: Linked Open Data
• = Open Data sets that can be cross-queried because they have been reconciled together• Ozwillo Datacore holds data that is shared between applications of the Ozwillo app store : geographical elements, organizations, reusable app business data...• Datacore OCCI(ware) use cases = Datacore « configuration as a Service » use cases
- letting the user configure its own data models, their rights and governance policy, define custom indexes, deploy dedicated data Caches as a Service...
• => demo of OCCIware Studio & Runtime's first features- demo 1 : try to Dockerize current Ozwillo production architecture- demo 2 : governance of Linked Data projects (and their models)

• Default configuration- backend : mnesia database (prototype, rather than Ozwillo Datacore in actual impl)
• OCCI extension configuration : Core, LDProjectvi sys.config
…
{occi_backend_mnesia,
[{schemas, [
{path, "/tmp/occi.xml"},
{path, "/tmp/org.occiware.ozwillo.data.models.xml"}]}]
},
…
• Let's start it :sudo docker run name="erocci_linkeddata" v `pwd`/sys.config:/tmp/sys.config v `pwd`/occi.xml:/tmp/occi.xml v `pwd`/org.occiware.ozwillo.data.models.xml:/tmp/org.occiware.ozwillo.data.models.xml P t i erocci/erocci

…to curl POST to runtime scriptGovernance action example :in order to publish a stable version of the org_0 project, let's freeze all its models :
*.occic configuration file > Cloud Designer > Generate curl script :curl $COPTS X PUT $SERVER/project/occiware_geo_1 H 'ContentType: text/occi' H 'Category: project; scheme="http://occiware.org/ozwillo/dcproject#"; class="kind";' H 'XOCCIAttribute: name="occiware_org_0"' H 'XOCCIAttribute: frozenModelNames="[*]"'

What now ?
• Next : turning this Linked Data as a Service prototype into an actual implementation, on top of Ozwillo Datacore !• In the works : - Studio : more generators & connectors (ex. get current runtime state and update the diagram accordingly), more automated, more complete… - Runtime : generic erocci Java integration - Deployment integration, use case platforms development / deployment / setup...
