# Tags Metadata
A simple config system which stores metadata for tags inside `collections`.
`O_TagMetadataCollection`: This is the class that hosts a collection of metadata
Example:
To have the system pick up your collection, go into `Project Settings` -> `Plugins` -> `TagMetadata Settings` and add your collection to the array.
`O_TagMetadata`: The object that is added to the tags Metadata array to grant the tag whatever data you want to add.
Example:
The system comes with three functions to retrieve the metadata:
Example to retrieve the metadata:
## Notes
* All of the collections are hard referenced by the config, meaning they are loaded at all times. Be very mindful of what assets you are referencing and always use a soft reference.
* This system is meant for fixed variables, modifying any variables on the metadata objects during runtime is not recommended.
## Base Classes
* `O_TagMetadata` - The metadata object that will host your custom data.
* `O_TagMetadataCollection` - The collection that hosts the metadata objects and associates them with a tag.
## Change log:
### 1.2
* Collections are now soft referenced. Note, the functions will instantly load a collection if it isn't loaded. So use async load first. for optimal streaming.
### 1.1
* Collections now prevent identical tags.
* Added editor utility widget.
* Added `EditorAssistant` support
