OTG Event Model

A LOD Event Ontology to Describe the Lives of Enslaved People

On These Grounds

How can we design and disseminated a shared LOD model to describe the lived experiences of the enslaved people who labored for colleges and universities?

  • Not transcription
  • Not collections finding aid
  • Not object metadata
  • Derived
  • Interpretive
  • Often related to entities outside the purview of cultural heritage collections

Meso-Level data

1

Document description case studies

2

Develop Simple Model that uses single class with common properties to describe all events.

3

Develop Event Type controlled vocabulary.

5

Create description for testing universe documents using both models.

4

Design Complex Model with event classes derived from the controlled vocabulary.

6

Select and refine the model that adequately describes the domain while also being usable.

No one wants to write their own linked data....

even if it's in a simple form like Turtle.
