| - | If the local submodel being published depends on other local submodels, those dependencies are published as user submodels as well. | + | When a local submodel is published as a user submodel, its dependencies become local submodels of the published submodel, rather than independent user submodels of their own. |
| - | Consider a local submodel **A** that depends on local submodels **B** and **C**, where **B** also depends on **C**. Publishing **A** as a user submodel produces three independent, top-level user submodels: **A**, **B**, and **C**. The dependency relationships between them are preserved — **A** uses the user submodel **B** and the user submodel **C**; **B** uses the user submodel **C** — but all three now exist as separate entries in the user's submodel set, each individually available for use in other models. | + | Consider a local submodel **A** that depends on local submodels **B** and **C**, where **B** also depends on **C**. Publishing **A** as a user submodel produces a single user submodel, **A**, containing **B** and **C** as local submodels of **A**. **B** and **C** sit side by side inside **A**'s own local submodel set, so **B** does not get a separate copy of **C** — it uses the single copy of **C** held by their common parent **A**, the same way one local submodel depends on another local submodel of the same model. **B** and **C** are not added to the user's submodel set as independent, top-level entries — only **A** is. |
| + | |||
| + | This flat structure holds regardless of whether **A** uses **C** directly. Even if **C** is used only by **B**, and not by **A** itself, publishing **A** still places **B** and **C** side by side as local submodels of **A** — **C** is not nested inside **B**. | ||

| Publishing or sending a submodel again — whether because the local submodel changed, or because a user submodel of the same name already exists for some other reason — behaves differently depending on the target: | Publishing or sending a submodel again — whether because the local submodel changed, or because a user submodel of the same name already exists for some other reason — behaves differently depending on the target: | ||
| - | * **User submodels are overwritten by name.** Publishing a local submodel as a user submodel always replaces whatever user submodel currently holds that name, whether that is an earlier published version of the same submodel or an unrelated existing user submodel that happens to share the name. This also applies to any dependencies published as user submodels: republishing **A** likewise overwrites the existing user submodels **B** and **C** with their current definitions. | + | * **User submodels are overwritten by name.** Publishing a local submodel as a user submodel always replaces whatever user submodel currently holds that name, whether that is an earlier published version of the same submodel or an unrelated existing user submodel that happens to share the name. Since dependencies become local submodels of the published submodel rather than independent user submodels (see [[#dependency_propagation_when_publishing_as_a_user_submodel|Dependency Propagation When Publishing as a User Submodel]] above), republishing **A** does not touch any independently named user submodels **B** or **C** — it simply replaces **A**'s local submodels **B** and **C** with their current definitions. |
| * **Store submodels are versioned, not overwritten.** Sending a submodel to the Store again does not replace the previous submission; it creates a new version, tagged with the Dinamica EGO version in use at the time, following the same versioning behavior described in [[#versioning_and_compatibility|Versioning and Compatibility]]. | * **Store submodels are versioned, not overwritten.** Sending a submodel to the Store again does not replace the previous submission; it creates a new version, tagged with the Dinamica EGO version in use at the time, following the same versioning behavior described in [[#versioning_and_compatibility|Versioning and Compatibility]]. | ||

| The store submodel package therefore ends up containing two independent copies of **C**: one local to **A**, and one local to **B**. Once packaged, these copies are independent of each other, the same as any other local submodels obtained through copying (see [[#copying_importing_a_local_submodel_between_models|Copying (Importing) a Local Submodel Between Models]]). | The store submodel package therefore ends up containing two independent copies of **C**: one local to **A**, and one local to **B**.

| + | Unlike publishing to a user submodel, this nesting follows the actual dependency graph. If **C** is used only by **B**, and not by **A** itself, the store submodel package nests **C** inside **B** instead of placing it directly inside **A**: **C** becomes a local submodel of **B**, and **B** a local submodel of **A**. | ||
