  5. HL7 – IHE Collaboration • IHE: Integrating (imaging with) the Healthcare Enterprise • Project of RSNA + HIMSS (international) • Attracting other groups: ACC, pharmacy, laboratory • Not an SDO: Coordinate use of current standards in order to facilitate systems integration • www.rsna.org/IHE

TSC: Recent Ballot Results • Requirements: 60% vote, membership: 90% of Y/N = Y; committee: 2/3 Y/N = Y • Passed: • RIM committee ballot (with 13 negative ballots that need to be reconciled) • Failed: • V2.5 membership ballot: Needed 48 affirm votes, got only 20 affirm + 33 neg • V2 XML membership ballot

  8. Arden SIG • Arden v2.5: Transition to OO model • New syntax: explicit typing (OBJECT) and query (READ AS) • Reviewed related issues: • Time of objects (vs its attributes) • Applying (aggregation) operators to objects themselves (vs attributes): max, min, sort, etc • Assignment by reference vs value • Object creation outside of a database read • Action items: Develop use cases, refine syntax

  9. Arden SIG • Arden as XML: Reviewed proposed XML Schema • Explored further structuring of Citations slot • Refinement of notifier model: Further structuring of Write statement • Database references: Discussed model for using RIM classes, SQL and published vocabularies to create a standard Read statement
