 ** dependencyType **   <a name="codeartifact-Type-PackageDependency-dependencyType"></a>
 The type of a package dependency. The possible values depend on the package type.  
+ npm: `regular`, `dev`, `peer`, `optional` 
+ maven: `optional`, `parent`, `compile`, `runtime`, `test`, `system`, `provided`.
**Note**  
Note that `parent` is not a regular Maven dependency type; instead this is extracted from the `<parent>` element if one is defined in the package version's POM file.
+ nuget: The `dependencyType` field is never set for NuGet packages.
+ pypi: `Requires-Dist` 
Type: String  
Required: No

 ** namespace **   <a name="codeartifact-Type-PackageDependency-namespace"></a>
The namespace of the package that this package depends on. The package component that specifies its namespace depends on its type. For example:  
+  The namespace of a Maven package version is its `groupId`. 
+  The namespace of an npm or Swift package version is its `scope`. 
+ The namespace of a generic package is its `namespace`.
+  Python, NuGet, Ruby, and Cargo package versions do not contain a corresponding component, package versions of those formats do not have a namespace.
