Which technical requirements of my document do I have to consider?

Your publication should be submitted as an archivable PDF file. In order to allow for digital preservation, the files may not be password- or copy-protected. Files of a size up to 250 MB may be uploaded. For exceptions, for instance in the case of illustrated books with high resolution or contractual requirements from publishers which require copy protection, please contact us in advance.

Details
  • The Open-Access-Repository of the TH Wildau currently supports pdf documents.
  • The size of the file should be as small as possible. The system only accepts uploads of files of up to 250 MB size. If you need to publish larger files after consulting with us, skip the publication process when uploading the document and send us the document on a CD or DVD.
  • For the file name, we recommend a simple title without spaces or special characters such as underscores. Example: masterthesis.pdf
  • The document may not be copy protected or have other restricted access settings. This is a requirement by the German National Library in order to ensure digital preservation. Moreover, no provision is made for restricting access to the documents through OPUS itself, for example to certain IP ranges.
  • If your work contains programmes, files, video sequences, audio documents or similar on a CD enclosure, they must be prepared for publication as a compressed zip file and uploaded as well.
  • In case of any technical difficulties in uploading your documents, please fill out the rest of the form as far as possible and send your files via e-mail to opus(at)th-wildau.de.
Please submit text documents as PDF/A files if possible

Documents are usually published on OPUS in PDF format. In order to ensure digital preservation, the document must be saved in the standardised PDF/A format. PDF/A is an international standard that was developed especially for archiving documents. By storing documents in PDF/A format, the file's readability is ensured even when it is opened on computers on which the used fonts are not installed. In this format, all fonts and images used in the document are embedded and the metadata are stored in a standardised format.

Hints for creating PDF/A files

Information on the PDF/A format is available here (provided by the PDF Association). Many word processors nowadays allow a conversion into PDF/A format; alternatively there are many tools available on the Internet.

Example: In Word 2010, click Save as... and after choosing the PDF file format, click on Options and select ISO 19005-1 compatibility (PDF/A).

In LibreOffice (version 3.4 and up), open the Export dialog via the menu File / Export as PDF and select the option PDF/A-1a under the General tab.
