This is an RDF/OWL representation of the GeoSciML Geologic Timescale model, which has been adapted from the model described in Cox, S.J.D, & Richard, S.M. (2005) A formal model for the geologic timescale and GSSP, compatible with geospatial information transfer standards, Geosphere, Geological Society of America 1/3, 119–137.

The term 'era' in this context is generic. Geochronologic elements of all ranks are included, so the rank is given as a separate property.
the characteristic point or section corresponding with a geochronologic concept
This property points from a geochronologic element to a geologic feature

Geochronologic Era Rank
geochronologic era corresponding with this section
Stratigraphic Section
Stratigraphic Point
This property points from a geologic feature or event to a geochronologic element
