Subject: [OASIS Issue Tracker] Commented: (TOSCA-140) WD02 - Constraining the capabilities of multiple node templates
[ http://tools.oasis-open.org/issues/browse/TOSCA-140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=36712#action_36712 ] Thomas Spatzier commented on TOSCA-140: ---------------------------------------- The grouping concept in the current draft aims at providing a very simple to use way to express grouping for a couple of nodes, like drawing a box around some nodes in a diagram to gives this group some meaning. Right now, I would tend to keeping it really simple. For more sophisticated use cases we still have the possibility to group node templates in a nested service template that "implements" a node in a higher level template. I agree that the current grouping draft probably needs some thought and refinement, but I would still keep it simple. > WD02 - Constraining the capabilities of multiple node templates > --------------------------------------------------------------- > > Key: TOSCA-140 > URL: http://tools.oasis-open.org/issues/browse/TOSCA-140 > Project: OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) TC > Issue Type: Bug > Components: Profile-YAML > Reporter: Derek Palma > Assignee: Derek Palma > > In section 12 Grouping Node Templates, a membership construct is used to associate scaling constraints to node template instances. This construct has the following weaknesses: > 1) The members are not constrained, i.e. the types of the members are not specified > 2) The constraints enforced on the members are not defined. I.e. there is no reference to or ability to infer a schema for the constraints > A "type" approach which supports strong validation is more desirable. So far we have this for other aspects of the DSL so why not strive for strong validation for this construct too. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
