Work Item Proposals Discussed

1) MHD on FHIR R5 (parallel to R4)

Goal
  • Provide an MHD-on-FHIR R5 track in parallel to today’s normative MHD on FHIR R4. This does not deprecate R4.
Positioning / Fragmentation Concern
  • Creating an R5 line effectively introduces two MHD profiles (R4 and R5).
  • R4 remains the normative version and is the line presented and tested at IHE Connectathons.
  • The R5 line will be presented as a segment targeted to regions operating under EHDS needs (e.g., EU projectathons), without signaling a global migration.
  • Packaging, branching, version suffixes, and page placement will be refined in Technical Committee meetings.
Editorial/Packaging Approach
  • Maintain a versioned branch of the MHD repository for the R5 work.
  • Publish as a separate major line with a clear suffix (for example, “-R5”) to avoid confusion with the 4.x line.
Technical Notes
  • Most of MHD is unchanged; the largest delta is in DocumentReference.
  • AuditEvent will be profiled directly for R5, with future alignment to BALP as appropriate.
  • Dependencies expected to remain stable or version-agnostic; MHDS update is out of scope.
Implementation Guidance
  • Support both Source and Responder options where relevant.
  • Keep options tightly scoped and testable.
  • Treat the R5 line as suitable for national/regional extensions and EHDS events while avoiding pressure on global sites to switch.
  • Running two live lines increases maintenance; keep diffs minimal and document precise deltas.

2) Full-Text Search for Document Sharing

Goal
  • Add server-side cross-document full-text search to IHE Document Sharing so clinicians can find relevant unstructured documents (e.g., PDFs) without opening each one.
Scope / Positioning
  • Complements existing metadata/structured queries (XDS/MHD, mXDE, QEDm).
  • Limit scope to MHD unstructured content search; leave structured extraction to existing profiles.
  • Define minimal, testable options (query parameters, response fields, snippet behavior, ranking hints).

Consensus

  • Proceed with MHD-on-R5 as a parallel line; R4 remains recommended.
  • Keep MHD-R5 scope limited to what is required for R5 alignment (no net-new functionality).
  • Continue technical exploration of Full-Text Search within MHD with tight, testable options.

Action Items

  1. John Moehrke: Set up the MHD-R5 branch and seed with the initial change list (DocumentReference diffs, AuditEvent approach, examples, and a cross-reference table).
  2. gematik participants (Michael Onken, Raik Kuhlisch) and interested parties: Provide EU/EHDS projectathon expectations and testing scenarios to guide scope and timing.
  3. Full-Text Search proponents: Draft initial option text for MHD actors and propose conformance test cases.
  4. Planning/Tech co-chairs: Define publication placement/labels so R5 is findable without implying replacement of R4.
