Citation variables used by digi-libris

About > Generating Citations
Copyright © 2015 by Bizgraphic, Geneva/Switzerland  -  Status February 2015
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

Custom variables used in digi-libris generic styles only 
 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 
Custom mapping for affiliation 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. 

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 downloaded content. 

Variables used in CSL styles 
CSL variables are listed on export as dMeta package or as plain XMP sidecar files under custom variables with citation_ prefix and under the namespace heading "http://purl.org/digilib/cita/" with citation: prefix. Those mapped to Dublin Core elements and/or terms are in addition also listed under the respective DC heading. 
Items marked with * are mapped to Dublin Core Elements, with ** to Dublin Core Terms, all others are stored as custom attributes with prefix citation:      

Source types   Only one of the following variables is allowed under variable Type : 
   article 
   entry 
   legal_case 
   patent    research-project 
   article-magazine 
   entry-dictionary 
   manuscript 
   personal_communication    review 
   article-newspaper 
   entry-encyclopedia 
   map 
   podcast    review-book
