ISO Data Type Extension Met with NCI at the Feb 2009 Intrachange Necessary for HL7 & CDA support – ISO types are object types XML-Schema: complexType Not typical data types like integer or datetime Agreed to work on an extension to support the ISO data types Plan to start development of the extension later this year
DCR Extension DCR = Data Clarification Request – Data queries Needed for unambiguous exchange of clinical data – Eg. to generate Submission-Ready CRFs Currently collecting input – Plan to implement next year Send ideas or comments if interested
Null Flavors The “ not done ” checkbox on CRFs typically comes under the term “ Alternate Response Code ” or “ Null Flavor ” The team is discussing how best to represent this in ODM This work is in support of the CDASH work Send ideas or comments if interested
