XML Representation of SDO Change Summary [message #510699]

Hi,

I am trying to find out if the EclipseSDO library provides any help in converting a Change Summary to XML? I want to send just the changes to my SDO object over to a REST service using the HTTP PATCH method rather than sending the entire DataObject.

I remember from reading the SDO spec that the format for this is explained; but I just can't figure out the API. Sorry if I have missing something obvious.

Thanks,

Gerard

Hi Gerard,

The SDO spec itself does not currently define a standalone ChangeSummary XML representation.

Currently you could compose one yourself by interrogating the ChangeSummary object itself using getChangedDataObjects() and getOldValues(DataObject).

Coud you enter a bug for this feature? Also any requirements you have on the XML representation?

Done:

I guess though if we are missing a standard representation that this area might not be ready for standard usage as it would require EclipseSDO on the client and sever side.

Gerard,

I'm sure there are quite a few tricky problems to solve in such a
representation. E.g., how are the affected/involved objects referenced,
and how objects that have been added or removed referenced...
