 The Mannheim University Library aims for publishing as much bibliographic data as possible under a as free as possible license.
-But as many different institutions were and are involved in the creation of this data, we could not finally decide for a suitable license.
+The catalog data of the Mannheim University Library can be used as open data under the [[http://creativecommons.org/about/cc0|CC0 license]]. The datasets will be marked shortly, additionally there will be the possibility to download the raw data and the RDF version.
-So the provided data initially only contains the inventory data of the Mannheim University Library, that means, only data that are also accessable via the online catalog.
+The same is true for the catalog data of the university libaries of Tübingen and Konstanz, which can be accessed here as well, as all data from the SWB is currently loaded.
-We encourage and permit experiments with our Linked Data Service, i.e. the inclusion of the data in own applications and the linking with own data.
-However, we ask for a **[[http://data.bib.uni-mannheim.de/kontakt_en.html|consultation]]**, if you include the data in publicly available or productively used applications. **The dissemination or permanent storage of the data, as well as any commercial use are currently not allowed.**
+We also loaded the data of the [[http://www.hbz-nrw.de/projekte/linked_open_data/index_html|USB Köln]], which are available under the  [[http://creativecommons.org/about/cc0|CC0 license]]. The processed data is provided also under the CC0 license, that means all triple that have a subject URI within the range of <http://data.bib.uni-mannheim.de/data/hbz/...>.
+All other data from SWB and HeBIS is provided for demonstration purposes only. We can not give you a license for the use of the data, please ask the BSZ or HeBIS if you have any further questions.
+You see, the use of data can be quite complicated, if different licenses are used. How to provide such licensing information together with the data is therefore very interesting and subject of the [[http://wiki.bib.uni-mannheim.de/dc-provenance|DC-Provenance task group]] of the Dublin Core Metadata Initiative, in which we are taking part.
+Best compatibility is reached, if the data is provided without any restrictions, like by means of the CC0 license.
 == Why are the data not freely available as Linked Open Data? ==
-Linked Data and Open Data are two different aspects, hardly related in the first place. Linked Data describes the technical aspect of providing data in RDF and thus making them embeddable in linked data applications. Open Data means that data - in arbitrary formats - is made availabe under a free license and usable for others. Often, these two aspects are mixed and refered to as Linked Open Data.

+As said in the above response about the license, we aim for free data. As university library, however, we can only decide for our own data, which consequently is provided as open data.
+With this service, we are concerned about the technical aspects of linked data and we want to try different things with it and experiment with this technology.
-As said in the above response about the license, we aim for free data. But currenty we are mainly interested in the technical aspects of linked data and this service is intended to experiment with this technology. Legal issues in the context of linked data are also very interesting, but have no priority for us at this early stage.
+However, the presentation of the data is could definitely be improved further, so we assume that there is no serious demand for a use in a production system at this point of time.
-Free bibliographic data is already available, by the way, but not (yet) as linked data: [[http://www.hbz-nrw.de/projekte/linked_open_data/index_html|Open Data Website of the HBZ]].
+== Where can I download the data? ==
+Our data is available here (MARC21): https://wiki.bsz-bw.de/doku.php?id=v-team:daten:openaccess:start
+Data of HBZ libraries can be found here: https://wiki1.hbz-nrw.de/display/SEM/Aktuelle+Open-Data-Exporte
