Adam Heath commented on OFBIZ-3848:
-----------------------------------
brainstorming...
When a direct conversion A-B is not found, the following pseudo code would function
1: Note a visit to A
2: Find all A->Foo
3: Note a visit to all Foo
4: Find all Foo->Bar, except for those nodes that have already been visited
5: If Bar == B, note cached result, break
6: swap Foo, Bar
7: goto 3
For each new registered conversion, clear the cache.
This would work for UomConversions, and for the conversion framework.
> Add support for derived UOM conversion factors

https://issues.apache.org/jira/browse/OFBIZ-3848> Project: OFBiz
> Issue Type: Improvement
> Components: framework
> Reporter: Scott Gray
> Assignee: Scott Gray
> Priority: Minor
>
> Say we have 3 UOMs A, B and C, and we have UomConversion records for:
> A -> B
> B -> C
> currently the convertUom service in unable to directly convert from A -> C
> I propose we add support for automatically deriving conversion factors by walking the available conversion paths until an appropriate path is found.
> Comments are welcome, this is mainly just a TODO reminder for myself though.
