	Description	Mins	Owner	Notes & Actions
1	Welcome and introductions	5	@Peter Williams @Rob Hausam	Recording, notes & attendance. SNOMED on FHIR meeting planned during the business meeting - closed session (observers space dependent).
2	October Business Meeting/ Expo - Vancouver	5	@Peter Williams @Jane Millar	@Peter Williams work with @Rob Hausam to prepare agenda for Business meeting. Suggestions for additional agenda items. @Peter Williams to send out pre-meeting reading list with agenda.
3	Summary of previous week	5	@Peter Williams	2018-09-04 - SNOMED on FHIR Meeting (TB)
4	Work suggestions from last meeting	40	@Dion McMurtrie	Proposals for expand @Dion McMurtrie to progress the proposal through Zulip @Rob Hausam to create tracker item to socialize this for the next FHIR Release (R5 2019 Q3?) Hold for Zulip discussion. Options for validate code - mapping between various data issue scenarios and true/false result flag. All to review options. Note that validate code applies to both ValueSet AND CodeSystem. Examples would be helpful, with expected responses (could be used to drive unit tests also). Note that changes suggested are additive in nature, rather than "breaking". RH: FHIR Ballot currently open, closing on 24 September. Published late December/January.
5	SNOMED with FHIR	30	@Rob Hausam	Revisit 4.2.1.0 Using SNOMED CT with FHIR All participants are invited to review this local copy of that page. Section 4.2.1.0.5 Clarity needed on which Normal Form is being represented (eg breaking sufficiently defined concepts down to their primitive components, unlike what is supplied in the browser). Further discussion needed on what these properties are being used for. Perhaps only 1 is necessary since terms can be added/removed as required. Update 28 Aug: A link to the definition of NNF is desirable (MAG - define what this should be for PCEs?) Supplements are a possible way to allow language reference set type functionality.
6	Main item for discussion	30	@Dion McMurtrie	SNOMED CT Canonical CodeSystem resource Review and attempt to resolve detail questions Issue around extensions and what this CodeSystem resource actually represents Update: URIs populated. Intention to provide short URLs for normalForm and normalFormTerse to point to appropriate definition of terms. Update 28 Aug: Official endpoint should be hosted somewhere (SI?)
7	Current items	10	@Dion McMurtrie	SNOMED CT "Universal" Edition Definitely useful to have a catalogue of all concepts ever issued if not a proper edition which may be much harder? Is this work for this group, or should this be handed on to a more appropriate SI group? Update 14 Aug - Are we going to shelve this item as not currently practical? Hand to MAG/TRAG? Check and fix ECL in the FHIR spec Is there a way to systematically identify all ECL expressions in the FHIR spec? If we run these through validation is there appetite/volunteers to review and fix them as feedback to the spec? Is there a way to integrate ECL validation into the FHIR spec tooling to prevent recurrence? @Rob Hausam to progress Michael's tracker item on this issue. @michael lawley to follow up on URIs to Normal form and Normal Form Terse definition @Rob Hausam to progress returning NormalFormTerse to the page. @Former user (Deleted) to progress defining Terse Normal Form with the Family of Languages group (@Rob Hausam confirms needed for July) SLPG agreed that the Languages group is not the appropriate forum for this definition. Instead, we believe this should be defined in the DL subgroup of the Modelling Advisory Group. Also agreed that the terms that need defining are "Canonical Normal Form" (which is terse by definition) and "Necessary Long Normal Form" Update 14 August See draft (doesn't specify particular normal forms) :
8	Mechanism for working with Languages.	15	@Reuben Daniels	HL7 Vocab Item: https://gforge.hl7.org/gf/project/fhir/tracker/?action=TrackerItemEdit&tracker_item_id=15806 ML: Supplement would hopefully only add additional descriptions that are not described in the base content. Precedence (fallback) for multiple language reference sets only really discussed in Languages Group for ECL - other use cases not yet brought to light. Update 28 Aug: Keen to see an implementation using Supplements to see how it would actually work. Option to explore this at Baltimore Connectathon? Language reference set could be an implicit code system supplement. Update 11 September Do we need a parameter for the expand operation for this - Reuben looking into this currently. @Peter Jordan to supply material as offered for next meeting - thank you!
9	Valuesets / Refsets	5		@Daniel Karlsson's question about ValueSets also being published as Reference Sets with additional descriptions. @Daniel Karlsson Done?
10	Any other business			Next Meeting: Tuesday 25 September Actions for next week:
