Subject: [OASIS Issue Tracker] Commented: (CAMP-44) Clarify resource type issues and API
[ http://tools.oasis-open.org/issues/browse/CAMP-44?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=35499#action_35499 ]
Gilbert Pilz commented on CAMP-44:
----------------------------------
Tom,
The CORBA spec has some good material in it, but I don't want CAMP to go nearly that deep into the subject. CAMP doesn't define or use any IDL, doesn't have things like the "::" operator and, most importantly, doesn't define operations as part of the resource type but instead as part of resource *instances* (via the per-instance "operations" reference). I think the following is the main thing we want to borrow:
"It is illegal to inherit from two interfaces with the same operation or attribute name, or to redefine an operation or attribute name in the derived interface."
This implies that we need redefine our "common attributes" as a base type that all CAMP resources inherit from, otherwise its impossible to stick to this rule.

> Key: CAMP-44

> Project: OASIS Cloud Application Management for Platforms (CAMP) TC
> Issue Type: Task
> Components: Spec
> Reporter: Alex Heneveld
> Priority: Minor
>
> There were several key questions about types that have come up in today's F2F:
> What type hierarchy will we use? Mark requests ability to define e.g. MyGreatDatabase which extends Database. (We could also have multiple inheritance / interface / etc.)
> How do we explore the type hierarchy? (The apidoc suggestion in CAMP-1 could come in here.)
> And do we permit dynamic attribute extensions -- e.g. a resource instance has values for other attributes not on its type? (Yes please!)
