Subject: RE: [sca-policy] ISSUE 7: Required intents on interfaces [Implicit addition of intents based on a service or reference's @requires list]
The policy spec should also describe why
an intent should be placed on an interface. I would propose something
like the following: “Intents should be specified on
interfaces when they should be seen by both the provider and the client of the
service and should be treated as part of the contract between provider and the client.” I believe that the policy set selection
algorithm also needs to be modified to reflect these semantics. We could
do this by adding a step between step A2 and A3 which says: A 2.5. If the target element is a binding,
include all required intents defined on the interface that provides the type
for the service or reference that the binding is on (i.e. follow this path: binding->service->interface->@required). Michael From: Joshi,
Kaanu [mailto:Kaanu.Joshi@patni.com] Hi, Please find the link to
the JIRA system: http://www.osoa.org/jira/browse/POLICY-7 The subject has been
modified to: Implicit addition of intents
based on a service or reference's @requires list Regards, Kaanu Joshi PS: In conformance with
newly adopted issues process. From: Michael
Rowley [mailto:mrowley@bea.com] TARGET: SCA Policy Framework Specification DESCRIPTION: The input specification to the SCA Assembly TC has the
following paragraph starting at line 900: The @requires attribute can be applied to WSDL Port
Type elements (WSDL 1.1) and to WSDL Interface elements (WSDL 2.0). The
attribute contains one or more intent names, as defined by the
Policy Framework specification [10]. Any service or reference that uses an
interface with required intents implicitly adds those intents to its own
@requires list. However, the policy framework
specification has no description of what it means for a policy intent to be
required by an interface. I believe this definition belongs in the policy
framework specification. PROPOSAL Add this paragraph (or something
similar) to the policy framework specification.
