  • what’s in 2.0? Formalised semantics; what breaks?

Ian McNicoll AQL - ELEMENT-level querying

Example:
SELECT
el/name/defining_code as someElement
FROM
EHR e
CONTAINS COMPOSITION c
CONTAINS OBSERVATION o
CONTAINS ELEMENT el
WHERE
el/name/value/mappings/target = 'SNOMED-CT::12345'

• could we do ELEMENT-level querying on e.g. OBS-based Entries

• ex: get PEWS total score value via code in defining_code or in mappings

• Erik Sundvall - definitely exists where need to query on code system A but data are recorded in internal codes, or other code system (hence looking in mappings).

• Assumption: the codes we want to query on are in the data

• Requirements:

  • PRIMARY NEED: get back (e.g) OBS on the basis of term codes used to tag them, without knowing archetype or at-code etc

  • possible subsumption inferencing needed (actual codes in data are children of query code)

  • possible lookup of mappings that are not in the data, but may be in archetypes

  • make the AQL query simpler / more intuitive,

  • dirty import data scenario: need to use the codes that came in the data

  • handle terminology-tagged OBSERVATIONs (presumably other ENTRYs also)

• Seref Arikan can get a (probably unwanted) permutations effect - question on DISTINCT semantics etc

• ACTION: find out from vendors if ELEMENT-level querying allowed / works / …

Conformance update

Thomas Beale

Pablo Pazos : Need to harmonise service model with REST API (reverse from REST API);

Thomas Beale , Matija Polajnar : concretely conformance has to be against ITS not abstract specs.

Next SEC call

Agenda items for next call:

• Seref Arikan (Personal) Archie-based TS generation based on JSON schema.

• Ian McNicoll AQL ELEMENT/term matching question - precise use case please
