| 3 | Discussion Phase 1 dataset for migration trial | 57 min | | - Review of progress with conversion file for UK labs
- Modelling issues suggested by classification of Phase 1 migration set
- Followup on issues from last meeting:
- Timed specimens shall be identified by instance time stamp of acquisition
- 24 hour urine testing deferred to committee deliberation
- Red cell indices such as Mean corpuscular volume. Representation of averages (or any aggregation) has not yet been finally agreed on,proceed with proposed model
- Anti-mitocondrial antobody pattern, Leukocyte ALP → items deferred to Observables deliberation
- Agglutination test. Property = Presence, , Technique = Latex agglutination
- Titre. How to represent titre in relation to presence and quantity concentration; deferred to committee
- Von Willebrand factor activity - likely a process observable and out of scope.
- Produce an OWL file based on decisions made and compare hierarchy of reclassified Observables to Evaluation procedures.
2021-11-03: - James R. Campbell presented work since last time.
- DK: additional, the differences found between the Evalualtion procedure hierarchy and the E2O Observable hierarchy have highlighted issues with the Evaluation procedure hierarchy.
- Discussion about future progress of E2O
- UK current decision is to use Procedures in the context of ordering
- There would in the UK content not be duplicates between "ordering" and "result" concepts.
- Keeping two hierarchies with essentially the same meaning introduces maintenance challenges
- There would be modeling solutions to keep hierarchies in sync, IFF it is possible to write clear guidance on when to use which hierarchy
2021-11-17: - Next steps would necessary include the creation of templates for the common lab areas
- Inactivations of groupers such as "Sodium measurement" - replacement with e.g. "Sodium ion quantity concentration in liquid substance"
- Yongsheng Gao propose to create new SCTIDs for Observables and create "link" between Evaluation procedure and Observable concepts.
- Templates is a good way to get agreement on the application of the (generic) Observables model.
| - Daniel Karlsson Bring up generic aggregate observable topic on a future Observables meeting.

Hi Daniel Karlsson James R. CampbellI have added a radically pared down set of Jim's slides, a subset of the Meeting 20 set. I have added some comments and suggestions, trusting they are useful.
