The Lernfunk media aggregation, enrichment and distribution system can import media of any type, administer it, add metadata and export these media. It is centered around a Core REST webservice. Thus it is easy distributable and extensible.
The basic idea is to have a single system which aggregates all types of media created and held by other systems and distribute these to the “end-user systems” (portals, etc.) rather than connecting each “creating” system with every single portal directly.
This way it is easy to manage all media, its metadata and the places they should appear from a single system.

- aggregate media from different sources
- distribute media to different destinations
- manage metadata
- versioning of media
- handle different languages
Python is the main programming language used for Lernfunk3. However, as the modules communicate with each other using HTTP you can basically use any programming language you like for building new modules.
REST over HTTP is used for communication between modules. This makes it easy to create a distributed environment for the system and furthermore does not enforce the use of a specific programming language or operating system.
MySQL is used as database backend.
