It is similar to a bst file and specifies how the bibliography should be formatted. The specification is written as an XML file, for example, this is the specification for APA style: https://www.zotero.org/styles/apa-5th-edition The detailed schema is here: https://github.com/citation-style-language/schema/tree/v1.0.1 There are a large number of such specifications available. For example: https://www.zotero.org/styles So, the user can easily search for a style that matches his/her needs and simply use it. The task of finding a reference from a reference database is left to a CSL processor and there a few of them available: https://citationstyles.org/developers/ In principle, it should be relatively straight forward (but tedious) to write a processor in Lua. But I am not volunteering for that :-) Aditya ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________
