esMD+PPA+UC1+Harmonization+Meeting+Minutes+4-18-2012

**Time: 10:00 AM EST**
Discussed updates to esMD Data Model made during Face-to-Face. Discussed the esMD failure table:
 * See face-to-face meeting minutes for detailed description of updates
 * The table identifies possible scenarios that would lead the Payer entity to return a failure message to the Registration Requestor’s request for electronic registration
 * Added a failure: Provider is unknown to payer
 * Added a failure: Unknown signature format
 * Currently have ‘Status’, ‘Failure Reason(s)’ and ‘Pending Reason(s)’ as elements in the data model. These three elements will be revisited in light of selected standards and may retain individual identity, or may be merged into one or fewer (than three).
 * Sources of failure include:
 * Message Integrity
 * Hash does not match
 * Message Format
 * Message format does not meet existing standards (SDO dependent)
 * Required elements are missing
 * Message version not supported
 * Digital Certificate
 * One or more digital certificate formats does not meet x.509 v3 standards
 * One or more digital certificates not issued by or chained to a trusted authority
 * One or more digital certificates failed verification
 * Support team will flush out the reasons.
 * Signature Artifact
 * Message Format
 * Registration Requestor
 * Identity of Provider
 * Service requested
 * Options for the service
 * Provider Directory
 * ESI

Discussion about whether this is relevant now or we need to wait for Use Case 2 to be completed to address this.
 * Decision to address now, because there is no response in Use Case 2 and this work will need to be done at some time in order to either select a standard or identify gaps in a standard.
