Subject: [OASIS Issue Tracker] Commented: (TOSCA-18) Resource Requirements and Capabilities in TOSCA

    [ http://tools.oasis-open.org/issues/browse/TOSCA-18?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=30859#action_30859 ] 

Kevin Wilson commented on TOSCA-18:

Nice advancement.

1) How will versioning impact Capabailities and Requirements. 
2) Can we extend Capabailities to include WF interface definitions in addition to the parameters so that a inversion of control model can be implemented between nodes. 

ie Lets say we have a Web app Sugar CRM that has a Deploy WF. 
The Deploy WF may be dependent upon the container which is hosting the Sugar CRM application. 

It would be nice if the Surgard CRM Deploy WF could delegate the deploy action to the Web Container WF.

ie. If run in Jboss standalone, .. The deploy may copy the war/ear provided by SugarCRM App to the standalone/deploy directory. Other web containers may have a slightly different deploy directory.

> How will TOSCA enable the specification of resource requirements to enable performance modeling of TOSCA-described entities.  Performance modeling - to some degree - will be necessary to ensure that those entities, once deployed, will be able to meet SLA and similar performance requirements. What is the relationship?
