All exchanges on the Network require XML schemas. The guidance documents listed in this section provide information on XML schemas and describe Exchange Network schema design rules and standards. Compliance with these design rules, incorporation of data standards, and the use of shared schema components will promote interoperability and efficiency.

Collaboration, standardization, and reuse are central features of the Exchange Network. Before you begin developing schemas for a new data exchange, please consult the Data Exchange section of this site or consult an Exchange Network contact to ensure that you do not recreate something that already exists.

Network Partners updating or creating an exchange must perform a documented review of their schemas' conformance with applicable Network standards and design rules. The purpose of this review is to maximize compatibility and opportunities for reuse. The review makes sure the exchange uses Exchange Network standards and design rules and encourages the use of best practices.
