### Build Aspect Model Loader Library

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/documentation/js-sdk-aml-guide/modules/ROOT/pages/index.adoc

Build the Aspect Model loader library by running the `npm run build` command. This command compiles the source code and creates the distributable library files.

```bash
npm run build
```

--------------------------------

### Git Version Tag Syntax

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/CONTRIBUTING.md

Specifies the syntax for Git version tags, including pre-release identifiers.

```text
vX.Y.Z-[pre-release-identifier]

Examples:
v1.0.0-RC1, v1.0.0
```

--------------------------------

### Update Index Files

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/documentation/js-sdk-aml-guide/modules/ROOT/pages/index.adoc

Update all index files under the `src` directory using the `ctix create ./src` command. This is useful for managing module exports in TypeScript projects.

```bash
ctix create ./src
```

--------------------------------

### Semantic Versioning Format

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/CONTRIBUTING.md

Defines the MAJOR.MINOR.PATCH format for versioning, including rules for incrementing each component based on the nature of changes.

```text
Given a version number MAJOR.MINOR.PATCH, increment the:
- MAJOR version when you make incompatible API changes,
- MINOR version when you add functionality in a backwards compatible manner, and
- PATCH version when you make backwards compatible bug fixes.
Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.
```

--------------------------------

### Load and Group Namespaces

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/README.md

Load and group SAMM definitions by namespace. This is useful for organizing semantic concepts from multiple .ttl files.

```typescript
new NamespaceLoader().load(ttl-1, ttl-2, ttl-3, ...).subscribe((namespaces: Observable<Map<string, Array<BaseMetaModelElement>>>) => {
...
});
```

--------------------------------

### Load Aspect Model with Imports

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/README.md

Load an aspect model that may contain imports to other .ttl files. Provide the URN of the model and the string content of each .ttl file.

```typescript
new AspectModelLoader().load('<aspect-model-urn>', ttl-1, ttl-2, ttl-3, ...).subscribe((aspect: Aspect) => {
...
});
```

--------------------------------

### Load Aspect Model with Imports

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/documentation/js-sdk-aml-guide/modules/ROOT/pages/index.adoc

Load an Aspect Model that contains imports to other .ttl files. Pass the URN of the main model and the string contents of the imported .ttl files as arguments to the `load` method. The loaded model is provided as an observable Aspect object.

```javascript
new AspectModelLoader().load('<aspect-model-urn>', ttl-1, ttl-2, ttl-3).subscribe((aspect: Aspect) => {
... 
});
```

--------------------------------

### Load Self-Contained Aspect Model

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/documentation/js-sdk-aml-guide/modules/ROOT/pages/index.adoc

Load a self-contained Aspect Model (a .ttl file that includes no imports) using the `loadSelfContainedModel` method. The loaded model is provided as an observable Aspect object.

```javascript
new AspectModelLoader().loadSelfContainedModel(ttl).subscribe((aspect: Aspect) => {
... 
});
```

--------------------------------

### Load Self-Contained Aspect Model

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/README.md

Use this method to load an aspect model that does not import other .ttl files. The .ttl content is provided as a string.

```typescript
new AspectModelLoader().loadSelfContainedModel(ttl).subscribe((aspect: Aspect) => {
...
});
```

--------------------------------

### Find Model Element by URN

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/documentation/js-sdk-aml-guide/modules/ROOT/pages/index.adoc

Use the `findByUrn` helper function to find a specific model element within the loaded Aspect Model using its URN. Returns the element if found, otherwise returns undefined.

```javascript
let specificElement = loader.findByUrn(options.urnSelectedModelElement)
```

--------------------------------

### Find Model Element by Name

Source: https://github.com/eclipse-esmf/esmf-sdk-js-aspect-model-loader/blob/main/documentation/js-sdk-aml-guide/modules/ROOT/pages/index.adoc

Use the `findByName` helper function to find specific model elements within the loaded Aspect Model by their name. Returns an array of found elements.

```javascript
let specificElement = loader.findByName(options.selectedModelName)
```
