I downloaded several PDFs, including the "Nokia MultiMedia Messaging Service Center - External Application Interface FAQ".
In there it stated, and I quote:
"Q.2 Is EAIF a standarized interface or a Nokia proprietary solution?
A.2 Current MMS standardization does not completely standardize the application interface of the MMSC. The standards specify two alternative protocols, which can be used. Thus the external application interface complies with the standardization, but some of its function are Nokia proprietary."
I don't understand it. I thought WAP-230-WSP defines the protocol to be used, and thus, it should also be used between an MMSC and an external application ... or anything that interfaces with an MMSC for that matter. I am here equating the "application interface" == "protocol" ... and use HTTP 1.1 functionality.
What am I missing? Which part is proprietary?
