Abstract: This paper proposes a kind of method that can preserve integrity constraints in data mapping, contrives a mechanism (DAPPIC) of generating constraints-preserving publishing rules. The key technique and design of the DAPPIC are summarized. The implementation and application of CoXML reveal that these techniques work well in practice.

Key words: integrity constraints, data publishing, data schema
