Hi Ted,

I am a member of the OData Technical Committee (TC).  Chet submitted the request for OASIS on behalf of the OData TC.  You are correct, in OData 4.0 the Headers were titled OData-Isolation and OData-EntityID.  In the latest OData 4.01 spec the header name was changed to just Isolation and EntityID.  The OData- prefixed versions are still supported for backwards compatibility.  This change was made based on feedback for users and implementors of the OData standard.  I gather your preference would be that we use the OData-prefixed version for the registrations.  If so I will need to discuss that with the TC and get back to you.

Hi Chet,

I'm a little confused on one point.  The Isolation header states that it was called OData-Isolation in version 4.0, but the linked ABNF document says:


isolation  = [ "OData-" ] "Isolation" ":" OWS "snapshot"
That seems to indicate that both ODate-Isolation and Isolation are expected to be valid for this token.  The ABNF for EntityID is similar:


entityid   = [ "OData-" ] "EntityID" ":" OWS IRI-in-header

Can you clarify the intent here?  Are both expressions of this token expected to continue?

In general, "Isolation" seems to be a very general concept, and the reservation of it, unadorned, for a single token use ("snapshot") is somewhat surprising compared to the more-obviously scoped OData-isolation.  EntityID seems similar board in possible usage outside the OData specification.

regards,

Ted Hardie
