Agenda and Meeting Notes
Description Owner Notes Welcome and agenda Discuss postcoordination guidance strategy Find the leaves of a set of concepts - example use case (find the proximal set in the international core / or in the IPS) - example: Find the root concepts of a set of concepts - example use case (find the proximal set in the international core / or in the IPS) - example: Discuss current work on developing postcoordination guidance Scope for SLPG? Potential requirements for ECL v2.1 - Discussion and brainstorming We've done history for concepts but not for any other components... Realizing the information on inactive concepts is different and more extensive from other components, {{ + HISTORY... }} is (just) sugar and maybe just maybe there might be reasons to sprinkle other components with this sweetness (or not). Examples: previously active refset members (and their fields), previously active descriptions (e.g. Refers to association refset), ... << 56265001 |Heart disease| OR For example, I can write: << 404684003|Clinical finding| : 363698007|Finding site| = <<66019005|Limb structure| << 404684003|Clinical finding| . 363698007|Finding site| But I can't get all the attribute names that are used by << 404684003|Clinical finding| What refsets is a given concept (e.g. 421235005 |Structure of femur|) a member of? Example 1 - Dentistry / Odontogram Example 2 - Terminology binding Example 3 - Mapping Example 4 - Natural Language Processing Practical Guide to Postcoordination Proposed Transformation Rules - Refinements (NOT in valid domain of focus concepts) 363443007 |Malignant tumor of ovary|: 272741003 |Laterality| = 24028007 |Right| ON HOLD - How to refer to an 'extended edition' using a URI - e.g. "International Edition plus the following 2 nursing modules: 733983009 |IHTSDO Nursing Health Issues module|and 733984003 |IHTSDO Nursing Activities module| Use Case - Need to execute an ECL, that refers to "^ 733991000 | Nursing Health Issues Reference Set (foundation metadata concept) |" and/or "^ 733990004 | Nursing Activities Reference Set (foundation metadata concept) |", where the substrate includes the international edition, plus the modules that include these reference sets July 2020 International Edition URI: http://snomed.info/sct/900000000000207008/version/20200731 July 2020 International Edition + nursing modules URI ?? - For example: Expression Templates Examples: [[+id]]: [[1..*] @my_group sameValue(morphology)] { |Finding site| = [[ +id (<<123037004 |Body structure (body structure)| MINUS << $site[! SELF ] ) @site ]] , |Associated morphology| = [[ +id @my_morphology ]] } Note that QI Project is coming from a radically different use case. Instead of filling template slots, we're looking at existing content and asking "exactly how does this concept fail to comply to this template?" For discussion: Is it correct to say either one of the cardinality blocks is redundant? What are the implications of 1..1 on either side? This is less obvious for the self grouped case. Additional note: QI project is no longer working in subhierarchies. Every 'set' of concepts is selected via ECL. In fact most reports should now move to this way of working since a subhierarchy is the trivial case. For a given template, we additionally specify the "domain" to which it should be applied via ECL. This is much more specific than using the focus concept which is usually the PPP eg Disease.

Close-to-user-form - IF the grouping of the refinement is not concept model valid THEN
If there is a single (non-self-grouped) role group in the definition of the focus concept, then any ungrouped (but groupable) refinements are merged with this role group
If there is more than one (non-self-grouped) role group in the definition then flag as ambiguous and require refinement
NEED TO FIND a realistic clinical example where this may occur // Prevent failing cases from coming up // use template
ALTERNATIVE: Refinement is applied to all (non-self-grouped) role groups in the definition
Self-grouped attributes in the refinement are grouped on their own - i.e. Priority, Due to, After, Before, During, Clinical course, Temporally related to, and all Observable entity attributes (see Relationship Group)
Self-grouped attributes in the definition of the focus concept(s) are left unchanged

Close-to-user-form - IF the refinement's attribute is not valid for the domain of the focus concept THEN
