Plains2Peaks DP.LA Service Hub for Colorado and Wyoming

A regional DP.LA service hub using BIBFRAME and BIBCAT

Plains2Peaks Temporary Logo

In 2016 the State of Library of Colorado started an effort to provide a DP.LA service hub for states of Colorado and Wyoming. This project uses BIBCAT to transform different formats and vocabularies from multiple sources including Denver Public Library's RDF Dublin Core, Colorado College and University of Wyoming MODS metadata, and a metadata provided as custom Comma-Separated-Value file from the History Colorado museum into BIBFRAME 2.0 entities stored in a triplestore.

BIBCAT uses RDF-based rules, based upon RDF Mapping Language to ingest these different types of sources while allowing for easy customization and modification through simple editing of RDF turtle MAP file.

Build-Measure-Learn (BML) Iteration One

For the pilot DP.LA service hub, we are targeting approximately 50,000 source records to ingest into our RDF triplestore as BIBFRAME 2.0 Entities. We are actively building out BIBCAT's functionality to generate an XML ResourceSync that will link to JSON-LD representations of the BIBFRAME Works, Instances, and Items as DP.LA Metadata Application Profile version 4 (MAPv4).

MODS Example from Colorado College Digital CC

Van Diest Map from Colorado College

MODS short for Metadata Object Description Schema is a Library of Congress XML metadata format used in many digital repositories, particularly those repositories based on Islandora.

For this example, the BIBFRAME Item will be the link to Van Diet Maps in Colorado College's Islandora repository at https://digitalcc.coloradocollege.edu/islandora/object/coccc:6286 and the BIBFRAME Instance is a minted URI with base url of https://plains2peaks.org/ followed by a UUID. The source MODS XML is transformed into the following RDF triples in Turtle format:

Dublin Core Example from Denver Public Library

Native American on Horseback

The Denver Public Library uses OCLC's ContentDM to host their over 100,000 digital objects in their repository. ContentDM currently exports Dublin Core metadata records that we then transform into BIBFRAME RDF triples. The BIBFRAME Item URI is the link back to the ContentDM at http://cdm16079.contentdm.oclc.org:80/cdm/ref/collection/p15330coll22/id/6 the BIBFRAME Instance URI is minted https://plains2peaks.org/3e89592c-e40f-11e6-8180-005056c00008.

Here is the BIBFRAME Output in Turtle Format
