# Concept Creation

Snow Owl provides full support for a concept model, which dramatically simplifies editing.

### Modeling method <a href="#editingsnomedctcontent-modelingmethod" id="editingsnomedctcontent-modelingmethod"></a>

Snow Owl enables selecting the preferred modeling method by using either the proximal parent or the proximal primitive supertype for concept authoring.

The *Proximal primitive parent(s)* model selects the closest primitive parent in the hierarchy to the concept being modeled. By using this modeling method, inferred attributes from the selected concept are automatically added to the new concept as stated attributes. After running the classifier, more accurate inferred parents will be identified.&#x20;

{% hint style="info" %}
This method is recommended by SNOMED International, as it reduces the maintenance of parent relationships and increases the accuracy and breadth of supertypes and subtypes.
{% endhint %}

The other modeling method is *Proximal parent(s).* Here, the direct parent is used regardless of its definition status. Attributes are not copied over to the new concept, as the classifier will inherit them as needed.

Both modeling options are available when creating a new child concept.

When creating a new sibling concept, the modeling options are not available. The defining *Is a* relationships of the selected sibling concept will be copied as stated properties.

### Module selector <a href="#editingsnomedctcontent-moduleselector" id="editingsnomedctcontent-moduleselector"></a>

In the *Create new child concept wizard*, users can also specify the module of the new concept, and the descriptions and relationships that are added primarily when the concept is created.

The module field is auto-populated with the primary module. On the main branch, the primary module is the module selected in the ![](/files/-M568DHOLdMYQPX9y1Qd)*Snomed CT Settings*. On a task branch, it is the module that is firstly added to the task scope when the task is created. When a user is creating concepts on a task branch, only those modules are offered for selection in the module picker that are in the task's scope.

{% hint style="info" %}
When adding new relationships and descriptions to a concept on the Overview Page, the module of the new components will always be the primary module by default, regardless of what module the concept belongs to. To be able to specify a different module than the primary for the new component, go to the dedicated concept editor tab (Description/Source Relationship Page).
{% endhint %}

After selecting the modeling method, the module, and finishing the wizard, the new concept's editor is displayed to allow modifications to the descriptions and attributes.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.b2ihealthcare.com/snow-owl-authoring-platform/editing-and-authoring/snomed-ct-editing/concept-creation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
