201605 Declarative Mapping
Declarative Mapping
This track will explore mappings and/or a useful subset of mapping tasks using declarative languages used to address interoperability issues.
- Pre-requisites: none
Submitting WG/Project/Implementer Group
- SOA Working Group
- CGIT (approval planned)
- CBCC (approvalplanned)
Justification
There is a recognized need for mappings to facilitate interoperability across HL7 products Following on the Birds of a Feather CDA to FHIR session in Orlando, there was an agreement among the participants to pursue declarative approaches or mappings. Objectives of the track include reuseable computable artifacts that can be saved / persisted as FHIR resources from the approaches presented in the Connectathon. SOA WG has already developed "cross-paradigm" mapping guidance intended to represent the same business content in more than on structure (e.g. CDA template to FHIR profile or V2 profile components)
Proposed Track Lead
Expected participants
The expected participants include:
- Keith Dudley / Grahame Grieve
- MDMI Open Source Project (several participants)
- David Booth (Yosemite Project)
- SAMHSA BHITS Project
- Members of the i2b2 on FHIR team
Roles
Map Designer
This is a software product that helps a user manager a set of mapping resources, and edit them, and test the mapping transform outcome interactively. Designer may offer additional assistance in Ux for mapping etc as desired. Designers implement use case #1
Map Executor
This will be an application that takes a set of map files or resources, a CDA document and produces a FHIR Bundle Document. The executor may be wrapped in any form desired.
Scenarios
1. Edit an existing map
Action:
The designer opens and edits the existing CDA mappings either from the map files (using the concrete syntax), or from the equivalent resources.
Success Criteria:
The map resources produced can feed into the second use case
Bonus Point:
Bonus points for being able to read and write resources from a server.
2. Execute a map
Action:
Take the CCDA draft maps, apply them to a CCDA example document, and produce a document bundle
- The test map is the one in the CCDA implementation (\maps)
- the test document is the CCDA example document distributed with the CCDA R2 (see [here]).
Success Criteria:
The output should be a Bundle that looks like [this - to be resolved closer to the day]
Future Step:
A future step will test the execution packaged in an operation on a FHIR Server.
