We are currently evaluating UBL to possibly adopt it into our next generation of business tools. We are facing a problem consisting mainly of the following:
The standard does not cover all the possible data fields/structures we need to deal with. We basically need to map from EDI X.12 messages to UBL and viceversa. The EDI is, as you know, really wide and is many times customized to the own purposes of who transmits.
A shipment may have many different associated dates: Ship Date, Deliver Date, Do not Deliver After, Do not ship after, Do not ship before, Do not deliver before, Expiration date for foods etc.. We found at least 20 different DateTime qualifiers that may have us map the DTM valua to a corresponding field in the UBL schema. It happens that the UBL does not contemplate all of those fields. In this case we would be forced to extend the standard to our own purposes.
So, my questions are at this point:
1. Can you provide an example of how to extend a UBL Purchase Order with a date of expiration for an item that is food?
2. Is there a guide to map common EDI documents to their corresponding UBL documents?
3. Can you provide an small example of code list extension?
Thanks a lot for your help,
