Subject: [wsrp-wsia] [I#91] Is setEntityProperties atomic?
The spec is currently silent on this issue. The three possibilities I see are: 1) Require that setEntityProperties be atomic. This essentially requires some sort of 2 phase processing of all producers/entities for setting properties. We would likely need to define how failing items are indicated to the Consumer. 2) Explicitly state that each property setting is the atomic item. In this case we should provide an explicit means of returning either the successful or failed set of properties. 3) Leave the decision up to the Producer/entity. This is analogous to how performInteraction in Edit/Config mode deals with this issue. The closest fault message we have in v0.8 is "OperationFailed" ... might want one a bit more specific, including specifying how the failing properties are indicated. I prefer the 3rd choice. As spec writers we are unaware of what the issues are for setting properties on a particular entity. We should provide mechanism for it to apply the granularity that is natural to it.
