The following variables are used in digi-libris Reader for the generation of citations in generic and CSL styles.
Variables are treated internally as Dublin Core Elements, Dublin Core Terms or custom attributes and externally, i.e. when exported as XMP sidecar file or directly embedded in a PDF, EPUB or HTML file with a dc:, dcterms: or citation: prefix under the corresponding namespace or as custom attribute/value pair under pdfx with the citation_ prefix. See http://citationstyles.org/downloads/specification.html#appendix-iv-variables for the official and current listing of acceptable CSL styles.
Attention: digi-libris saves citation specific variables as 'citation:' under namespace http://purl.org/digilib/cita/ (which points to this page).
Since third-party PDF documents may already include citation tags from other sources, Acrobat could alter the citation tag names on importing XMP sidecar files.
Typically '<citation:xxx>' might become '<citation_1_:xxx>'. Interpreting software should be aware and able to deal with this possibilty.
>> some items are mapped to citation variables in digi-libris Reader with different names
digi-libris supports the generation of arbitrary attribute/value pairs which are stored with the pdfx: prefix according to the XMP specification. The following digi-libris citation variable(s) are added to this list:
Affiliation: list of one or more institutions corresponding to the affiliations of author and co-authors.
Two types of notation are allowed in digi-libris: sequential = A, B, C if author plus co-authors in the same order and
numbered = 1 A, 2 B, 3 C with authors and co-authors numbered the same way. Author is always 1, co-authors can share numbers.
Custom mapping: Bridges are included or in preparation to facilitated the import of bibliographic references in other style sets (BIB, RIS, MARC21, MODS etc.) and to automatically map these to recognized CSL variables.
To permit further extension of citation-specific variables and to accommodate variables that may be used in other (proprietary) style sets, any variable marked as such with a cs:, citation: or citation_ prefix is recognized but only treated as such if it can be mapped to a recognized one. digi-libris allows you to dynamically re-map variables found in in downloaded content.
The following variables may be used with CSL styles.
Items marked with * are mapped to Dublin Core Elements, with ** to Dublin Core Terms, all others are stored as custom attributes
Items in blue are used and displayed by digi-libris but are not part of the official CitationStyles.org specification. To avoid confusion they are mapped to one of the official variables on export or exchange with third parties as XMP sidecar file.
