Greetings Dave, Exactly. In the case of a Core Data document based app, that is where I was scratching my head. Then it hit me. There would need to be an intermediate Shoe-Box app. It would actually provide the ERSync connection and a sublcass of NSAtomicStore. The document based app is a self contained Core-Data database. I suspect we could have a special naming convention in this case. Say have the name of the application and the location of the Core-Data database (its document) marshaled into the name of the client app. In other words, the document is the client app.
Of course the name of the application could also become the apiKey, in that special case. In any case, this something worth thinking about. I will probably have some fun tonight working on the Shoe-Box app that provides the ERSync connectivity. Hopefully, I continue to make some progress. Thank you, Daniel Beatty Computer Scientist, Detonation Sciences Branch Code 474300D 1 Administration Circle M/S 1109 China Lake, CA 93555 [email protected] (LandLine) (760)939-7097 (iPhone) (806)438-6620 P.S. I would also like to add the notion of a Domain Relational Calculus (DRC) style query to ERSync (WO side). The idea is that the DRC queries would also be associated with the device/app principle. Thus if a database is larger WO side than the capacity of an iPhone for example, the authorizer would check the queries to help govern the amount fed to the iPhone ensure that we do not overwhelm it.
