Basic Linked Data Resource for Temporal Information

RDF Resources of calendrical periods such as date, month, and year were defined, and provided as Linked Open Data. These resources clarify the temporal ranges of various temporal expressions and enable their comparison on a common temporal axis, even if they are based on different calendars. These functions cannot be realized using only ISO 8601 (widely used as standard date expression). It is expected that these calendrical period resources will be applied to new and existing Linked Data, and bring new possibility into the Linked Data world.
