Custom metadata for file object

1 Initial Problem

You cannot use custom metadata for file objects so far. Especially when lots of files are used custom metadata would be helpful for filtering.

2 Conceptual Summary

1. Global Custom Metadata can be created in the the Metadata section of the global Administration and File shows under "Assigned Objects".
   • Custom Metadata Sets can be imported and exported
2. Files can be assigned with Custom Metadata.

3 User Interface Modifications

3.1 List of Affected Views

Global Administration

• Administration > Metadata > Custom Metadata > Datasets table > Assigned Objects gets a new entry for files
• Administration > Metadata > Custom Metadata > Add > Assigned Objects gets a new entry for files
• Administration > Metadata > Custom Metadata > Presentation sub-tab > new entry for files

• File > Metadata gets new sub-tabs "LOM " and "Custom Metadata"

3.2 User Interface Details

3.3 New User Interface Concepts

The accessibility implications result from the implementation in the advanced metadata 

3.4 Accessibility Implications

4 Technical Information

5 Privacy

No new data worth protecting is stored directly by the feature. The privacy information of the Advanced-Metadata (no document yet) applies.

6 Security

The File object is given the ability to use AdvancedMetadata according to the instructions (see https://github.com/ILIAS-eLearning/ILIAS/blob/trunk/Services/AdvancedMetaData/README.md). The permissions are checked by calling the metadata (see Modules/File/classes/class.ilObjFileGUI.php:131)
