PaceExplainDuplicateIds


Abstract

Weakens the constraint on duplicate entry ids in feeds to a SHOULD.

Status

Open

Rationale

The proposed compromise to allow duplicate IDs in feeds, on the condition that a source element is present, doesn't address the problem of quick scripts that probably won't group duplicate IDs. This means that compliant processors will still differ from one-off hacks. Rather than legislate the constraint, we should explain the situation, and give the validator a SHOULD-level requirement so a warning can be triggered.

Proposal

Remove the bullet point that reads

 atom:feed elements MUST NOT contain atom:entry elements with identical atom:id values. 

Add a paragraph after the list that reads

Atom Processors use the atom:id element found in Atom entries to identify 
distinct entries. It is RECOMMENDED that each entry in an Atom Feed Document 
have a distinct atom:id value.
