On October 8-9, 2018, Matrix hosted a second meeting in East Lansing, Michigan, with Enslaved project partners to share updates and collectively work through the data model.

Over two breakout sessions, the Enslaved project partners refined controlled vocabulary terms for key Enslaved concepts such as Person Status, Event Type, and Document Type. Matrix presented on the outcomes of the first phase of the project and the group made plans for the implementation phase. The partners also discussed preparations for the upcoming Enslaved: Peoples of the Historic Slave Trade conference that will be held at MSU March 8-9, 2019, as well as the future inclusion of additional partners to the larger Enslaved project.

Partner projects reported on progress they had made aligning individual datasets with Enslaved core metadata fields and the Linked Open Data framework. Matrix provided updates about the website design, metadata enhancements, and the project’s data model (ontology). The Matrix team also showed partners samples of Enslaved data in our current installation of Wikibase. This demonstration helped partners see how Enslaved will use its data model to structure data to promote connections across disparate datasets. Finally Matrix elaborated on the Enslaved Wikibase ecosystem by providing an overview of OpenRefine, QuickStatements, and BlazeGraph.

The principal partners in attendance were Walter Hawthorne, Enslaved co-PI from Michigan State University (MSU), Paul LaChance from the University of Ottawa, Jane Landers and Jessica Fletcher from Vanderbilt University, Sharon Leon from MSU, Henry Lovejoy from the University of Colorado – Boulder, Paul Lovejoy, Erika Delgado, Fernanda Sierra, and Luisa Cruz from York University, Keith McClelland from University College-London, Gwendolyn Midlo Hall of Rutgers University and MSU, Steven Niven from the Hutchins Center at Harvard, Daryle Williams from University of Maryland, Daniel Genkins from the John Carter Brown Library, Jim Schindling from West Virginia University, Kathe Hambrick from the West Baton Rouge Parish Museum, and Ina Fandrich, a consultant on Louisiana history and culture from New Orleans, LA. Also in attendance from the Matrix team were Dean Rehberger, director, Ethan Watrall, co-director, Ryan Carty, Catherine Foley, David Glovsky, Jeff Goeke-Smith, Alicia Sheill, Duncan Tarr, Liz Timbs, as well as Jeff Mixter from OCLC. Pascal Hitzler, from Wright State University, participated in a working group to discuss the Enslaved data model.
