[17:53] George Ericson (Dell): dropped again

[17:56] Ralf Handl (SAP SE): Mike: don't rely on order of properties in $metadata (not possible with CSDL JSON), instead have the context URL list all returned properties in the order they are filled into the arrays

[17:56] George Ericson (Dell): Looks similar to protobuf

[18:02] Ralf Handl (SAP SE): Mike: always use an array with an object at position 0 that contains the annotations

a.George: describe use case and why containment navigation properties arent sufficient

i.Sometimes want to store the values of an entities properties, for example storing representations of entities in a log message.

In that case, dont want the behavior features of the entity and no relationship, just a snapshot of the structural values.

[18:36] Ralf Handl (SAP SE): George: can't have a relationship to the "snapshot instance" as it doesn't have an identity

[18:37] Ralf Handl (SAP SE): George: also want Collection(entity type) as a type of a structural property

[18:37] Ralf Handl (SAP SE): Basically treat the entity type as if it were a complex type if used in a structural property
