Introduction

This is a project under the CEN ISO HL7 Joint Initiative

This is a project page for the ISO datatypes activity led by Grahame Greive for HL7, and Tom Marley for ISO.

The project is currently in reconciliation activity -- with the work being done on the XML SIG telcons XML SIG#Conference_Calls.

Note: this page was a full draft of the ISO datatypes document - this is now maintained in the hl7 svn repository, and published in the Ballot pack [1].
