DROPS in a nutshell...


Dagstuhl has been operating DROPS  - the Dagstuhl Research Online Publication Server - since 2004.
As an online publication server, it intrinsically enables very timely publication of and access to recent research results. DROPS complies with all formalities required by a publication server like

  • administrating library meta data,
  • ensuring long term availability of the documents (assignment of  persistent identifiers, archiving will be done by the German National Library).

Furthermore, DROPS offers some additional services like

  • very timely dissemination of recent research results,
  • enhancing findability of the documents by indexing e.g. at DBLP, and
  • connection to library networks.

The series published via DROPS are


Dagstuhl also dissseminates its own publications via DROPS, e.g. the annual report:

Some Details about DROPS




Dagstuhl does not only all the necessary administrative work for the author...

  • Collection of all necessary and some additional bibliographic meta data (according to Dublin Core)
    • Authors, title, abstract, keywords,...
  • Assignment of persistent identifier (for long term access to the document)
  • Long-term availability of the documents will be guaranteed by the German National Library which collects all publications, archives them and provides future acces, e.g. by conversion to future formats or virtual machines that simulate present environments in the future.

      => Citability of the document is guaranteed.


      Dagstuhl also accomplishes some additional services like

      • Indexing  at DBLP, the computer science bibliography of Michael Ley, University of Trier,

      => Findability of the documents is enhanced.


      Server / Software


      DROPS is based on the OPUS software used for the documents- and publication server of the Online Publikationsverbund der Region Stuttgart. OPUS is the result of a research project funded by the German Research Net (Deutsches Forschungsnetz) and the Federal Department of Higher Education and Research (Bundesministerium für Bildung und Forschung).

      Publishing with OPUS means: converting the electronic document to PDF (portable document format) and writing some meta data about it, which will be stored in Dublin Core format using a mSQL-database. Retrieval will therefore have the typical functionality of other well known online databases - different search fields, truncation options, Boolean operators etc. The Library of Congress (LoC), the  Online Cataloging Library Center (OCLC) and a number of other national libraries like Die Deutsche Bibliothek (the german national library)  are engaged in Dublin Core during several projects. Dublin Core makes it possible to participate in ongoing developments concerning web based search engines and robots.

      Format of the Documents

      The only file format accepted for publication is currently PDF. This is to ensure long term availability of the document and conversion to future formats as well as conformance to collections of online publications by e.g. the  german national library.
