- Minutes from 20140827_FMG_concall John moves approval seconded by Lloyd. Unanimously approved.
- DSTU Update
- Paul will continue researching the fixes and send documentation. Site was not accessible on last week's call. http://www.healthintersections.com.au/fhir/history.html reviewed. From the history they reviewed a representative example in JSON to validate. Paul moves and JohnM seconds endorsement of the DSTU update/correction.
- Lloyd will check with Grahame on what the resolution to the bandwidth limitation might be. End of month rollover has temporarily fixed the problem.
- Registries: FMG and EST has approved the registry requirements. What does Lloyd need to do next. It needs to go to HQ for RFI. Paul checked with Andy and noted that the EST has approved the requirements and now they have to send out the RFP. Andy/EST will be taking the responsibility to bring that forward to HQ/Karen. Then Lloyd as project facilitator will shepherd the next steps. They will report when updates are available.
- Connectathon management (David/Brian)
- FGB –
- FGB Risk Assessment and Fundamental_Principles_of_FHIR for FMG review and comment
- Review Fundamental principles on-line and Risk assessment offline
- Paul expresses concern over the forwards and backwards compatibility representation in the version numbering. For forwards compatibility we must express the prohibition of new elements. Lloyd notes they support the ability of implementers to identify new elements. John thinks we need more explaining. If more needed to be done it might be added as a new resource and inherit from an existing resource.
- Lloyd notes that the principle exists though the explicit methodology has not been defined. Paul notes that if we state this as an achievement and not a goal we need to be able to assert the method.
- David offers "FHIR will strive to be forwards and backwards compatible". We cannot have instances where new elements make prior elements required.
- Lloyd states as long as one can tell what the effective version that this instance is intended to be compliant with… you shouldn't have to have an instance that declares conformance to a specific version of FHIR.
- John notes you can only validate conformance against the core spec. Other conformance claims would have to include reference to the profile. These sub-principles should perhaps be expressed also.
- Need a proposed methodology to handle versioning and forward compatibility to demonstrate ability to adhere to this principle. ACTION ITEM: Lloyd will draft the document.
- Do we need to wait for that document review before we sign off on this one? John would like to wait but we can begin review on the rest.
- Primary objective: prioritize implementation. Again we need to be able to assert how we adhere to the principle. When we make changes or additions we make them in such a way that maximizes adherence to these principles. Lloyd edits the wiki page.
- Do we need to add the implementation patterns of push-pull, messages vs documents, etc.
- Trade off complexity on the server versus the client, the side of the transaction likely to be more capable.
- Uses/constraints should be centered about a profile.
- Other edits made to wiki page and will be reviewed with FGB. One section still requires work and another requires some additional supporting documentation.
