Why DeepGreen?
Who can participate?
DeepGreen is aimed at all scientific publishers with whom authors from German scientific institutions publish. The prerequisite is that full texts and metadata can be supplied in NISO-JATS format. In particular, the metadata must contain affiliation information.
How does it work?
Publishers send their data to the DeepGreen router via SFTP. The deliveries consist of ZIP files, each containing an xml file with metadata in NISO JATS format and a PDF file with the full text of the article. Our technical specification [link: to PDF document] describes the details.
The DeepGreen router automatically assigns the articles to the respective repositories. Institutional repositories receive articles if at least one author works at the respective institution according to the affiliation information in the metadata. In addition, delivery can be restricted to institutions that enjoy special Open Access rights, for example through licensing agreements.
Subject repositories receive articles in accordance with their individual subject-specific profile, irrespective of the author’s affiliation. This is determined in advance by an ISSN list.
As soon as matching has taken place, you can see in your publisher account which data has been assigned to which repository.
How much does it cost?
The DeepGreen service is free of charge for publishers.

Repositories
Why DeepGreen?
Who can participate?
DeepGreen is aimed at institutional and subject repositories in Germany.
For institutional repositories, registration with the Electronic Journals Library (EZB) is a prerequisite for participation in DeepGreen. DeepGreen uses the license information from the EZB for the assignment of articles and the assignment of participants is based on the EZB ID.
Subject repositories are not required to participate in the EZB.
How does it work?
Publishers send article data consisting of metadata in NISO-JATS format and full-text PDFs packaged in ZIP files to the DeepGreen data hub. DeepGreen’s first step is to check which institutions are licensed to receive these articles. If article data has been sent to your institution, it must be checked before publication in your repository whether your institution is actually authorised to publish these articles. In the next step, the affiliation assignment takes place. To do this, the affiliation information from the metadata is compared with the name variations that the institutions store in their accounts. In the case of subject repositories, affiliation matching is not performed, and articles are only assigned on the basis of the journals selected by the subject repository.
After registration, repositories receive a DeepGreen account. In this account, they can see which articles have been assigned to them. In addition, the so-called affiliation file can be maintained here – a list with as many name variations of the own institution as possible. Since the assignment of articles is based on this file, the more extensive it is, the better! In addition to the affiliation file, information about the SWORD interface can also be stored.
DeepGreen offers three interfaces for querying article data – OAI-PMH (for metadata only), Web API and SWORD. In addition to the JATS format supplied by the publishers, DeepGreen also offers the OPUS-XML and METSMODS metadata formats for retrieval.
How much does it cost?
There are no costs for participating repositories during the pilot operation.
