Subject: [OASIS Issue Tracker] Updated: (ODATA-74) Explicitly mention dynamic navigation properties
[ http://tools.oasis-open.org/issues/browse/ODATA-74?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Pizzo updated ODATA-74:
-------------------------------
Proposal: Make their existence explicit (see comment below on relationship between open properties and open navigation properties). (was: Make their existence explicit.)
Must a type be marked open in order to have open navigation properties?
I would think not; services may expose additional navigation paths, for example, without being able to expose dynamic properties; we should not conflate the two.
Data properties are part of the instance and a client may need to know that dynamic data properties exist in order to handle "unknown" properties in the payload (i.e., for roundtripping). This should be the unique meaning of the "Open" attribute. Open navigation properties are exposed as additional navigation links, and the client should always be prepared to deal with additional links from any instance (it should not depend on the Open attribute, nor should we need to add another attribute to specify that open navigation properties may exist).
