Bibliography (module for Omeka S)

New versions of this module and support for Omeka S version 3.0 and above are available on GitLab, which seems to respect users and privacy better than the previous repository.

Bibliography is a module for Omeka S that adds features to manage a bibliography with standard citations, reference lists, suggested values, and collected records from doi, isbn and other identifiers.

  • The canonical bibliographic citations of resources are displayed according to any managed citation style.
  • Some record suggesters are added for the module Value Suggest in order to get multiple unique identifiers from DOI, ISBN, ISSN, OCLC, LCCN, OLID.
  • Full bibliographic citation can be added through the module Collecting, and even the full record.

The module adds basic output for some bibliographic formats for the module Bulk Export too.

The doi and the issn are retrieved from the open service of crossref (a free registration allows to get a better performance for service). The isbn, the oclc, the lccn, and the olid are retrieved through the OpenLibrary api from Internet Archive.


This optional module Generic may be installed first.

To use suggesters, it is required to use this version of Value Suggest, that contains all patchs, not yet integrated upstream. For the same reason, it is required to use this version of Collecting to create a collecting form with suggesters. To output resources in admin or public side, the module Bulk Export should be installed.

The module uses external libraries, so use the release zip to install it, or use and init the source.

See general end user documentation for installing a module.

  • From the zip

Download the last release from the list of releases (the master does not contain the dependency), and uncompress it in the modules directory.

  • From the source and for development

If the module was installed from the source, rename the name of the folder of the module to Bibliography, go to the root of the module, and run:

composer install --no-dev

If you used the module Citation, it is automatically uninstalled: its features are the same and improved in this module.


Ontology FaBiO

The ontology FaBiO uses external ontologies for some classes and properties, mainly the Dublin Core and Prism, and some others like FRBR. For easier management, these related ontologies are not installed automatically, because generally, the elements they uses are rare or can be replaced by the bibo ones.


Once the specific version of Value Suggest is installed, the following identifiers can be requested:

  • DOI: Works
  • DOI: Journals
  • DOI: Funders
  • DOI: Members
  • DOI: Licenses
  • DOI: Types
  • ISBN: International standard book number
  • LCCN: Library of Congress Control Number
  • OCLC: Online computer library center
  • OLID: Open library id from Internet Archive

In the config of the resource template or the collecting form, some items above can be requested with different values. It allows to choose between a large query with keywords, or a strict query with the id. It allows to set the label too, that can be a name or an id according to properties, for example the title or the article for dcterms:title, but the id for bibo:doi, or even the full reference for dcterms:bibliographicCitation, or even the full record as a resource.

Creation of the citation

The citation can be displayed with any managed citation style, in any of the managed languages.

Remarks on the metadata:

  • The process is based on the resource class, that allows to adapt the style. If the class is not present or not managed, the citation may not be accurate.
  • The journal (for an article) or the book (for a part) should be referenced as dcterms:relation or dcterms:isPartOf.
  • The date should be a numeric data type or an iso8601 formatted date, partial or full. The year should be on 4 digits.

Display of the citation

The citation is automatically added to the item/show page. You can have a better control on the display with module Blocks Disposition or direct edition of the theme.

To insert a citation in the theme, add this anywhere in any partial:

echo $this->citation($resource, $options);

Default options are:

  • style (string): the citation style (default to "chicago-fullnote-bibliography").
  • locale (string): the locale for the citation (default to "en-US"). The language and the country are separated with "-", not "_".
  • defaults (array): The default values to use when a property is not set. It is mainly used for own specific items to set the creator, the date, and the publisher of own specific records.
  • append_site (boolean): to append the site or not.
  • append_date (boolean): to append the access date.
  • bibliographic (boolean): if true, set append_site and append_date false.
  • mode (string): how to display the citation (option used to display it differently in various contexts). Default managed values are "list" and "single" (default). It may avoid to use a specific partial.
  • template (string): partial to use for display, default is common/citation. currently).

The default options are used for Omeka resources. You may unset options to append the site and the access date for real bibliographic resources. Any other option is passed to template.

The result can be customized via the template common/citation in view/.


  • Replace the library used to convert formats.
  • Improve conversion from dcterms and bibo into csl, or find a library for it. See
  • Use the dcterms:type if resource class is not present.
  • Add a bulk replacement from bibo to fabio.


Use it at your own risk.

It’s always recommended to backup your files and your databases and to check your archives regularly so you can roll back if needed.
