Intern:PDF

In established publications, a DOI is the persistent identifier to easily find the paper where ever it is located on the Internet. In Pangaea the DOI is part of the reference as defined in the table Reference in the field URI and appears as a hot-link in the citation of the metaheader of a dataset (e.g. . Still several papers, reports and periodicals, mainly from the grey literature, do not use identifier and mostly are just linked to a web site. Links to web pages are not stable on the long-term view (error 404) and should NOT be used in any link fields in Pangaea!

AWI is operating ePIC as a repository for publications, providing handles as persistent identifers to the objects archived in ePIC. In case a reference in Pangaea should be linked to its full text, ePIC might be used as the repository for the paper and the handle can be entered in the URI-field of Pangaeas reference table.

ePIC allows the upload of pdf-files. If a paper does not exist in electronic form, it might be scanned (300 dpi) and converted to text by OCR (optical character recognition). Following the standards for electronic archiving, the pdf should be saved as PDF/A which is the ISO-19005-1 Electronic document file format for long-term preservation.

The file is uploaded to ePIC by using the functionality New documentations. With the following metadata fields to be filled:
 * Author/editor names (define with Author-Number the required fields)
 * Year
 * Title
 * Source (periodical, institute etc)

After sending the information to the database, a requester for the upload of the pdf will appear.

If more than 25 publications in one step should be uploaded, the required citations can be provided in a table together with the pdf-filenames and -files and uploaded via a script by the ePIC master. PDF can also be uploaded without metadata. Access to ePIC with the required user profile Librarian have Lydia Gerullis and Hannes Grobe.

PDF may also be archived in the Elektronische Bibliothek der Staats- und Universitätsbibliothek Bremen which is providing a URN as persistent identifier (e.g. see reference in . Access has Lydia Gerullis.

Example:
 * Each citation has a handle, pointing to its splash page in ePIC:
 * The handle extended by *.d001 will open directly the linked pdf-file: . This is the one which should be added to the reference in Pangaea e.g..
