Hi David,
The GET URL used the singular "metadatum" which expects only to return a
singular object, hence it gives the error about the mismatch.
The "metaname" key is not globally unique, it is only locally unique to its
containing object, i.e. the service-instance in the BBS use case.
The "cvlan" metaname thus refers to many objects in the /nodes/ query and needs
to be returned in a list of objects.
To match the return types for a list of objects, use the plural name "metadata"
in the URL and add the metaname as criteria using query parameters e.g.
GET /aai/v16/nodes/metadata?metaname=cvlan
In order to DELETE an object, you need to match the resource-version for it, so
you need to identify a specific instance (there are no batch DELETE methods).
To GET and DELETE a specific instance of metadatum having metaname=cvlan, you
could use the full URL path rather than the /nodes/ query path, e.g.
GET
/aai/v16/business/customers/customer/{customerName}/service-subscriptions/service-subscription/{serviceType}/service-instances/service-instance/{serviceInstanceId}/metadata/metadatum/cvlan
DELETE
/aai/v16/business/customers/customer/{customerName}/service-subscriptions/service-subscription/{serviceType}/service-instances/service-instance/{serviceInstanceId}/metadata/metadatum/cvlan?resource-version=1559200312325
