The Jena Experiment has generated a wealth of data on biodiversity and ecosystem functioning since its initiation in 2002. In general, metadata of all datasets can be viewed by the public on request, and all data older than five years are freely available to the public. Please note that this deadline applied to the date when data were uploaded to the Jena Experiment Information System which usually takes place within two years of collecting the data. The research consortium of the Jena Experiment strongly supports data sharing, while ensuring that the data providers and the Jena Experiment get a fair credit for their work through co-authorship, citation, and/or inclusion in the acknowledgments of resulting papers. For this a data use and publication policy applies.

Procedure to be an external member

People interested in public data and in metadata of other datasets can become external users of the data base ("external members").

To register as an external member of the Jena Experiment , follow the URL below and create a new account. For registration, the applicant needs to fill out a form stating the intention that concern the usage of Jena Experiment data and providing correct personal information for future contacts.

To complete registration, applicants have to accept the Appendix to the Jena Experiment Data Use and Publication Policy and return a signed copy to the Data Manager. Registration as an external user is valid for one year and can be renewed. More details can be find in the workflow to be a member and accesses to data on the Information System.  

Access to metadata and publicly available data

Access to metadata and public available data via Intranet: http://jenaexperiment.ioe.uni-jena.de/Login/Account.aspx after registratin as an external member.

All data older than 5 years (currently 2008 and before) is publically available. The data will become available through the web-Interface in around July 2015. Until then, data can be obtained by writing a request to the data manager (Email)

Once the public data is downloadable in the database, an external member needs to search and select the datasets she/he is interested in. The system allows users to select multiple datasets using the "cart" Symbol. This allows a download of multiple datasets at once. The system automatically extracts information from multiple datasets into one or several spreadsheets for further use. Before the download starts, a questionnaire needs to be filled where the external user provides information about the purpose of the data download including the aim of the study and the type of analyses intended.
