In fact chat.fhir.org is a searchable forum, but it’s just not publicly indexed via Google I guess.
So there are issues of discoverability yes, but once you know about it, it’s huge and you get answers to direct questions quickly. There are thousands of people registered worldwide, but not everyone knows about it of course, so we keep trying to spread the word.
FHIR is actually very well supported on Stackoverflow though too @pacharanero, so that is another way in.
But @mayfield.g.kev it seems you are looking not for a forum but for content - pre-formed solution outlines that go beyond what is normally covered in any public space. You want written, implementable recipes for “how do I connect this to that for UK GPs” type problems, and all the other dozens of scenarios.
That would be a good resource. It sits somewhere between things like NHS ITK and the other more specific frameworks, open source software, and closed source solutions that people will want to sell to you (and that cost them a lot to create).
These tend to be complex problems with many issues that need to be solved depending on the exact context. But nevertheless establishing and documenting some patterns would help. Some of the mini-articles and blogs you have posted are really useful and going in this direction. In practice there are so many variables, situations and rules, hardware and software differences that these patterns can really only be fairly general. Often even a bunch of existing source code is not that useful, because it’s hard to integrate with what you have and may be difficult for you to extend and maintain.
As we know, FHIR and other similar efforts that led to it, have taken the approach of abstracting parts of the problem space to narrow down the amount of variation.
Solutions are easier to describe if you can assume that all the systems involved expose their data in a globally standardised web-based API. That would be nice, but systems change slowly, for non-technical reasons. However adding interfaces is relatively easy, given that there are now multiple good free toolkits, and it doesn’t involve a full rip and replace cycle.
