FYI there is an ontology for the geological timescale here https://github.com/CGI-IUGS/timescale-ont and a dataset representing the international chronostratigraphic chart nearby https://github.com/CGI-IUGS/timescale-data 
The International Commission on Stratigraphy are planning to adopt this as the point-of-truth for the standard geological timescale. 

This is possibly of overlapping scope with the DWC requirements.
