Period

The period reference data model provides a list of standard fields that are typically present in the general description of a temporal period, taken in the sense of descriptive, contentful timespan (e.g., the Renaissance) rather than abstract one defined solely in terms of start and end dates, though these periods may also be given approximate or overlapping start and end dates. The aim of this reference model is to cover basic descriptors that are typically employed in the documentation of a period. This reference model aims to remain at a general level description, providing a consolidated, high-level reference data model of most commonly reused descriptors for a period as such and to provide for these, in turn, a set of standard semantic mappings to the CIDOC CRM. Moreover, each field is marked with regards to its potential functionality with regards to instance matching between overlapping datasets. This level of modelling is seen as a necessary basic reference point on which to build more complex documentation.

Description	The period reference data model provides a list of standard fields that are typically present in the general description of a temporal period, taken in the sense of descriptive, contentful timespan (e.g., the Renaissance) rather than abstract one defined solely in terms of start and end dates, though these periods may also be given approximate or overlapping start and end dates. The aim of this reference model is to cover basic descriptors that are typically employed in the documentation of a period. This reference model aims to remain at a general level description, providing a consolidated, high-level reference data model of most commonly reused descriptors for a period as such and to provide for these, in turn, a set of standard semantic mappings to the CIDOC CRM. Moreover, each field is marked with regards to its potential functionality with regards to instance matching between overlapping datasets.
