About the Cartographic Extension

Harvard University is leading the development of an extension to BIBFRAME to describe cartographic resources including printed maps, atlases, and digital geospatial datasets.

Harvard Project Proposal

April 2017 Project Update

For questions or comments, please contact Marc McGee, Geospatial Metadata Librarian, mmcgee (at) fas (dot) harvard (dot) edu

  • BIBFRAME extension profile for cartographic resources
  • Set of published BIBFRAME descriptions for a variety of cartographic resource types
  • Written evaluation of the project and set of recommendations for future research and development
  • Presentation of project findings to appropriate library cartographic materials and linked data communities.
Current Activities

Last updated: 6/22/2017


  • Finalizing a set of ontology modeling recommendation papers/graphic models for cartographic-related concepts including:

    Projection (draft rdf examples)
    Spatial Extent - Bounding Box Coordinates (draft rdf examples)
    Scale (draft rdf examples)
    Relief (draft rdf examples)
    Types of Cartographic Resources (in development)
    Prime meridians (in development

  • Beginning to write ontology files to support cartographic extension concepts

  • Cartographic Materials application profile to begin soon

Community Engagement

  • Biweekly standing meeting of the Linked Data for Libraries Cartographic Materials Working Group,Thursdays 2-3p ET.

Completed Work

Last updated: 6/22/2017


  • Surveyed existing linked open data efforts in the library and geospatial domains (Aug. 2016).
  • Held a 2-day in-person Cartographic Materials Working Group ontology sprint modeling meeting, Harvard Library, Sept. 19-20, 2016.
  • Compiled initial set of use cases for cartographic metadata (Nov. 2016).
  • Identified and prioritized set of cartographic resources-related concepts for ontology development to support use cases (Jan. 2017).
