5. FHIR RIM mappings - What will RIM mapping look like? - What do we do when the RIM can't do it? - What will it achieve?

Will tackle #1 and #4 in this meeting, #5 slotted for joint FHIR/MnM discussion For Wed Q3, will host FHIR (will release room 219)

Motion: approve agenda for WGM - Woody/Patrick

RIM ballot reconciliation

1. Dale's 2 comments - not persuasive 7-0-1 (Woody/Grahame) 2. blocked context conduction relationships:

• will create value sets containing conductable act relationship codes
• can create a new value set that constrains the base value sets as per the rules in Core principles
• can create a fixed value that is a "list of codes" that draws from the codes in the value set
• need to verify this will propagate properly through the tools to the schemas
• will document this in Core principles

Motion: Woody/Grahame 5-0-0

Woody takes action item to update Core Principles

Based on the above, Woody withdraws his negatives

Topic: mustUnderstand

Discussion of mustUnderstand - Motion from G Grieve/Rik Smithies to "Rename mustUnderstand to isModifier, and add sentence saying that you must explain why it is that you think it is a modifier and/or what it modifies."

Approved 25-0-0

Topic: Various

Discussions around "messaging-like" paradigm with FHUR similar to V2, can be defined and has been tested.

Discussions on "Profile" resource and what is does. Is rather larger than desired. Was noted that although it is defined as a Resource, it is unlikely to be exchanged as instances.

Security and FHIR

There is a Wiki document in the "FHIR Publication" that is being built with the guidance of Security Work Group lists security-related issues when using FHIR, and how and where these might be addressed.

Distinction between "Type" and "Code" and Other field names

Rationale for discussion: "type" and "code" have been used as attribute names for what is likely to be an encoded result.

Discussion suggests that: "code" commonly adds NO understanding; should not repeat name of element in attribute; type works where it is the type of the element; code is not useful; if need further distinction and expand "type"

Similarly, "date" as an attribute name will beg the distinction of which kind of "date" (e.g. see V3 Act) is intended.

Usage of Terms like "Subject", "Author"

There were notes about inconsistencies of use of these terms. Discussion here suggests that:

1. Whatever definition for a term like "author" (for example) that FHIR selects should be consistent throughout FHIR
2. A Glossary would be very difficult (these tend to be more fine-grained than the usual glossary)
3. The RIM vocabulary (participation type codes, for example) provide fairly carefully thought out (and reviewed) set of definitions for things like "author", etc.

Suggest that FHIR consider adopting upper and lower camel case for names - lower for parameters and attributes, upper for resources and elements; etc.

Also the uniqueness criteria for names should be case agnostic. Thus "LastMan" and "lastMan" are not unique.

Also the uniqueness criteria should be case agnostic. Thus "LastMan" and "lastMan" are not unique.

Discussed McKenzie Discussion of "Subject"

Appears focused on context conduction and the need to clearly state what if ANY assumptions can be made thereabout. What if a contained object has no subject??

Discussion recognized that FHIR's light-weight reference mechanism makes it reasonable to represent the subject in (for example) each member of a battery of tests.

Discssion of mustUnderstand on optional Booleans

The line item 6 from McKenzie, is moot if all mustUnderstand have minimum cardinality of 1, which is currently on the "warning" track for becoming a rule.
