GELLO needs vMR

Many possible uses

• Data access for ARDEN syntax
• Criterion specification
• Message validation
• Calculated values
• Visibility/validation in editors
• GLIF/Other Guidelines
• Assessments and scales
• Eg CDAI, eGFR, GCS

Further Work

• Interface to vMR is loose currently
• Needs to be well described for compiler
• Compiler can read from idl or HL7 ocl
• Implementation of vMR
• Can be implemented with services
• Can be implemented with direct access
• Database
• Messages (eg CCD/Query)
• Subject of further independent work
