A problem can arise when using the vocabularies if, after exporting the data, Goobi viewer also needs to access the same vocabularies, as the Goobi workflow installation is often inaccessible from outside the facility network because it is located behind a firewall. For this reason, we have developed a new vocabulary server to which Goobi workflow mirrors all changes to the vocabularies configured in this way. In such a case, the URL of the data records in the publicly accessible vocabulary server, which is hosted by intranda and accordingly accessible worldwide, is entered in the metadata of the METS file. This means that the Goobi viewer can then access the vocabularies without any problems and always receive up-to-date data records from the vocabulary.
