Frequently asked questions (FAQ)

Where can I get test data?

Currently valid test data in the MARC 21 format (also in XML structure) can be accessed at any time via the respective link to the current deliveries of the desired metadata.
In addition the catalogue as well as the metadata shop offer access to data. In order to illustrate the regular format changes test data is available in the format MARC 21 (also in XML structure), and RDF (various serialisations). All formats are offered in UTF-8 decomposed character encoding.

Further processing

If you are just getting started with processing metadata, useful programmes include MarcEdit, MARC Specialized Tools, the software suite Catmandu, OpenRefine or Metafacture, while data can be analysed with "Konstanz Information Miner" (KNIME) or the Metadata Quality Assurance Framework. A more detailed overview is provided in the presentation slides "Open Source Software zur Verarbeitung und Analyse von Metadaten" (available only in German) and the article "Survey of Tools for Linked Data Consumption".
