A deep-time knowledge base and service

Deep time is a common reference in geoscience and many researchers are using deep time as a framework to synthesize datasets. Through an NSF supported research, we are building a deep-time knowledge base (DTKB) with semantic technologies. The knowledge graphs we built are based on community-level standards, and we have included a list of global, regional and local geologic time scales in a common framework. A SPARQL endpoint has been set up, and a number of use cases have been built to demonstrate how to use the service from workflow platforms, such as Jupyter. All the outputs are made open source and are accessible through a GitHub repo.
