A short experience report covering our journey of moving the TI-Messenger specification from Matrix 1.3 to 1.11


The gematik TI-Messenger (TI-M) is a Matrix-based national standard for an interoperable healthcare messaging system in Germany. We have recently migrated the TI-M specification from Matrix v1.3 to v1.11 and will be reporting on:

  • Challenges encountered in consuming and evaluating the spec changelog
  • Strategies taken to address incompatible changes and prepare for future removals
  • Support we've received and ways we've tried to contribute back
