Findings:

Current ui-plugin implementations mostly used for displaying/selecting entities from list. I think it's enabled because usually in ui-modules list components implemented as Containers - have its manifest, resources, etc. So ui-plugin-find-vendor just renders a Modal with Vendor's list component inside, passing down corresponding callbacks (selectRow and others).

...

I believe that one of valuable attribute is to make as less changes to existing ui-modules code as possible, so I see only one way: ui-plugin-create-item should be Container component, to whom user passes required properties (instanceId, locationId for example), it loads everything required to ItemFrom ui-inventory component from back-end and passes it down, as well as callback with POST API call to save new item. In this case no changes required to ui-inventory, but ui-plugin-create-item contains some business logic to fetch and post data (so dependency on okapi interfaces is introduced).

Summary:

According to slack thread there are plans to leverage edit of various FOLIO entities in a more common way across the whole platform. But since they are mostly long-term I think we can come up with current solution of using plug-in stripes system to reuse ItemForm of ui-inventory module. However, in comments Zak suggested to change my solution - to leverage ItemForm component from ui-inventory. I think we need to choose from these two ways. I'll attach diagrams with both ways as well as Pros and Cons of each.

My way, Pros:

no changes required in ui-inventory;
lest time required for implementation, since code is ready.

Cons:

Tightly coupled with ui-inventory code, so it depends on changes inside it. I think this could be partially solved with tests coverage in ui-plugin repo, so we can see if it's OK to work with future ui-inventory versions on the build (release) stage.

Zak's suggestion Pros:

ui-plugin-create-item is independent from ui-inventory and contains all things required to create item (no tight coupling on other ui-module);

Cons:

changes required to ui-invenotry (to use newly created plugin);
more time consuming in this case: to implement solution and check that no duplicated API calls to fetch data in Invenotry forms, etc. (may be important to Acquisitions PO);
