Wakao-san, I reviewed the document. The scenarios contain a good level of detail and they reveal some assumptions. For example, chart 3 assumes that the Acquirer can send an Excel file to the PROMCODE server and that the server can convert the Excel file into an RDF representation using mapping rules. However, we have not yet specified the format of mapping rules. Therefore, no one could implement this scenario by reading our spec. Are Mapping Rules in the scope of the PROMCODE specification? If PROMCODE is intended to support the upload and download of data in Excel format by the PROMCODE server, then that becomes part of the REST API and must be included in the specification. _________________________________________________________ Arthur Ryman Chief Data Officer SWG Rational 905.413.3077 (phone) 416.939.5063 (cell) IBM InterConnect 2015
