Abstract: Systems and methods for converting business to business data in standard formats into a canonical XML format. Translation is facilitated by the use of pattern files, that provide mappings from various data provider's unique data fields and arrangements to a canonical format that can be adapted to a user's requirements. Pattern files are assigned each to a data provider. If no pattern file is assigned, a new file is created and customized from a library of default pattern files. In some examples, the system includes multiple translation engines, each of which is geared to a particular B2B format. In some further examples, system and methods can be reversed so as to supply B2B standard data to a data provider from the user's canonical formatted data.
