ReferenceResource

Bases: EntryResource

The references entries describe bibliographic references.

The following properties are used to provide the bibliographic details:

  • address, annote, booktitle, chapter, crossref, edition, howpublished, institution, journal, key, month, note, number, organization, pages, publisher, school, series, title, volume, year: meanings of these properties match the BibTeX specification, values are strings;
  • bib_type: type of the reference, corresponding to type property in the BibTeX specification, value is string;
  • authors and editors: lists of person objects which are dictionaries with the following keys:
    • name: Full name of the person, REQUIRED.
    • firstname, lastname: Parts of the person's name, OPTIONAL.
  • doi and url: values are strings.
  • Requirements/Conventions:
    • Support: OPTIONAL support in implementations, i.e., any of the properties MAY be null.
    • Query: Support for queries on any of these properties is OPTIONAL. If supported, filters MAY support only a subset of comparison operators.
    • Every references entry MUST contain at least one of the properties.
