Is there an alternative to the CommerceML schema?

Question

1C

Interested in an alternative to the CommerceML schema.
By itself, CommerceML is completely satisfied, but purely for scientific purposes, maybe there are any alternatives, say from SAP or some other vendor?

Answer 1

EANCOM 2002 S3 for example (well, or look at the specific electronic document management format used by providers in your area). Not quite "e-commerce", but international.
