The project “Open Source Academic Publishing Suite (OS-APS)” aims to enable small and university publishers to publish easily and media-neutrally in Open Access. The open source software includes a document importer (i.e. for Word documents) and an editor to edit structures and metadata. Using templates, which can either be selected from a pool of existing templates or be created with a template development kit, the design of the exported PDF can be automatically adapted according to the format requirements of the publisher. In addition, e-books in EPUB and HTML format are created quickly and reliably.
