JSON, YAML and ODIN are all just object-dump serial formats that result from traversing an in-memory object graph, so it is a generic operation to generate them from tools (XML is more problematic due to being irregular in many ways and being schema-dependent).

In the case of archetypes, the dump is just of objects that are instances of the AOM <https://specifications.openehr.org/releases/AM/latest/AOM2.html#_the_archetype_package>, i.e., ARCHETYPE, C_ATTRIBUTE, various kinds of C_OBJECT and so on.

The ADL Workbench has an export mode (for I think around 5 yeras) that generates the first 3 for any archetype, and also a whole archetype library. The folks doing CIMI use at least the JSON mode. It also generates XML, via custom serialiser.

One of the jobs I never completed is a deserialiser for the 3 regular formats, but it is nearly trivial. I am not sure if Archie or Marand's ADL-designer tools do the same but I think it should be trivial for them to implement as well.

I will look into this again...

I always admired OpenEhr for its ability to notate archetype-definitions and now also BMM definitions in any type.

I saw experiments in XML, but the official endorsed notation language is ADL.


I wonder, would it also be possible to write archetypes and reference-models in JSON?

If so, it would save us tons of code, no grammars needed, no parsers needed. Many programming languages support JSON out of the box, with only some annotations needed. NoSQL Databases often support JSON, and have their own JSON-path based hierarchical query-languages.

Venkat Subramaniam, who is a java-guru, said: "Don't walk away from complexity, RUN!!!"

But Einstein said: "Everything Should Be Made as Simple as Possible, But Not Simpler"

So the question is: Are there any technical objections to express archetypes and reference-models in JSON?
