The Semantic Web and Linked Open Data promise to interlink diverse sets of data through subscription to uniform structures and standards. This formal and operational requirement subsumes individual ontologies into a single standard, which enables interoperability at the expense of specificity. The Heterochronologies project was devised to support the correlation and comparison of diverse ontologies without obscuring their epistemic and cultural specificity. The project regards temporality as an ontology expressed through various graphical and cultural representations of time, such as timelines and chronologies. TheTime Capsule is a software environment that embodies the conceptual, methodological and operational foundations of the Heterochronologies project.
