Subject: [OASIS Issue Tracker] Commented: (ODATA-351) Define ID, ReadLink and EditLink in Part 1: Protocol, define representation in Atom and JSON
[ http://tools.oasis-open.org/issues/browse/ODATA-351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33341#action_33341 ]
Michael Pizzo commented on ODATA-351:
-------------------------------------
Alternate proposal:
For JSON:
-We write the id for the object if it does not follow convention AND key values are not included OR full metadata is specified
-We write odata.id=null for "transient" entities
-We write the editlink if entry is updatable and (editlink is different from the id OR full metadata)
-We write the readlink if entry is read-only and (readlink is different from id OR full metadata)
-We don't write readlinks, editlinks, or ids for feeds
For ATOM
-We remove the selflink from feeds
-We allow an empty <id> element for transient entities (or, if we think that would break atom parsers, we define a naming pattern, i.e. <id>odata.transient;{some-generated-unique-identifier-to-not-break-atom-parsers}</id>
-We write editlink if, and only if the entry is updatable
-We write readlink if, and only if, the entry is read-only
-We continue to write an <id> for the feed, and say it uniquely identifies the collection from which the feed was generated.

> Key: ODATA-351
> URL: http://tools.oasis-open.org/issues/browse/ODATA-351
> Project: OASIS Open Data Protocol (OData) TC
> Issue Type: Improvement
> Components: OData ATOM Format , OData JSON Format, OData Protocol
> Affects Versions: V4.0_WD01, V4.0_CSD01
> Environment: [Proposed]
> Reporter: Ralf Handl
> Fix For: V4.0_CSD02
>
>
> In certain situations, especially Data Aggregation, we need the concept of "transient" entities and feeds in addition to the already defined "addressable" entities and feeds.
> Protocol should define the concepts ID, ReadLink and EditLink.
> Restrictions due to Atom and AtomPub
> - ID required, MUST be IRI
> - Feed: MAY have Self-Link to re-retrieve THIS feed
> - Entry
> -- Links are optional
> -- <link rel="self"> identifies resource equivalent to current resource
> -- AtomPub: <link rel="edit"> can be used to retrieve, update, and delete the Resource represented by that Entry
