With regard to ILIAS, the project builds on developments carried out by the ILIAS.nrw project. These developments are directly integrated into the ILIAS core and do not have to be retrofitted via plug-ins.
This common approach works like this: In ILIAS, content with OER licenses is collected by an integrated OER harvester and, after optional review by a local editor, moved to a public area. The metadata of the content in the public area is also made available via the open and standardized OER-PMH interface; it also contains a link to the content and a download link. This metadata can then be read by edu-sharing servers. They are used to generate an object in the Edu-Sharing repository, which can then be published in the repository after the content has been checked by the editors.
Together with the edu-sharing plug-in for ILIAS, which has been working for some time and allows the insertion of content from edu-sharing repositories in ILIAS courses, this enables a transfer in both directions and thus a comprehensive integration of the two services.
