IRSS: Migrate Media Objects to IRSS

1 Initial Problem

The underlying file system handling of the media object component has been deprecated by the file component maintainer and PM, see https://github.com/ILIAS-eLearning/ILIAS/pull/5158

Since this code is being removed by the file component maintainer with ILIAS 10 and we will not take over maintenance of the legacy code, we must migrate to the IRSS with ILIAS 10.

The [[[Project] ILIAS Resource Storage Service]] aims to centralize file related resouce handling and to improve security and reliability of file related actions in ILIAS. For a complete list of the projects objectives, please visit the corresponding wiki page above.

This page will deal with the necessary changes in the media objects component.

2 Conceptual Summary

The migration of the media objects component will need to tackle several different scenarios,

• use in page editor (learning modules, glossaries, wikis, and all other page editor use cases)
• in media casts
• in news
• in media pools.

File handling affects different kind of file types:

• media files itself (image, audio, video, ...)
• fullscreen variants
• thumbnails
• subtitle files for video
• overlay images for interactive images
• ...

All files need to be migrated to the IRSS. Exports are handled in separate feature requests.

2.1 Media Objects as IRSS Container

The media objects will be most pobably migrated to IRSS container, since they can include multiple files and even a directory structure (e.g. HTML media objects).
