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. Place The place reference data model provides a list of standard fields that are often found present in the general description of a place. Place here is interpreted as a geometric extent used for locating entities relative to a reference space. The scope of entities that this reference model aims to cover are places as typically documented in gazetteers. Examples of places would be Edmonton (the inhabited city), Alberta (the administrative district), Canada (the country). The aim of this reference model is to cover basic descriptors that are typically employed in the documentation of a place, usually by a gazetteer. 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 place 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. Builtwork The built work reference data model provides a list of standard fields that are generally present in the general description of a built work in a national built heritage data register. Built work is taken here in the sense of a - typically - immovable building, or significant individual part thereof, made for some human use-function such as habitation. The fuller documentation of a built work would establish the relation of the physical work to the series of intellectual and social processes related to the production of such works, such as architectural plans, meetings, construction episodes, detailed use and modification history, specific topological relations and so on. This reference model does not intend to cover such specificities but to remain at a more general level, providing a consolidated, high-level reference data model of most commonly used descriptors for a built work and to provide for these, in turn, a set of standard semantic mappings to the CIDOC CRM. This level of modelling is seen as a necessary basic reference point on which to build more complex documentation.

Rather, we are interested here in representing the types of information that are typically gathered by scholars relative to a publication in their creation of bibliographies for use in scholarship and used as the basis for citations. 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 bibliographic item 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. Digital Object The digital object reference data model provides a list of standard fields that are typically present in the general description of a digital object in a cultural heritage data system. A digital object is meant in the sense of a digitally encoded information object represented as bit sequences that have been encoded with a particular format and can be digitally decoded and represented to an end user of a digital information system. Digital objects are often stored as reference or documentation objects relative to cultural heritage items such as textual descriptions stored as PDFs, documentary images, 3D representations and so on. Digital Objects can also form cultural heritage objects in their own right, though this model does not aim to represent this potential aspect of the digital object. Because of the choice to model, the digital object in its role as a secondary documentary resource, the reference data model has been kept as light as possible. This reference model intends to remain at a general level description, providing a consolidated, high-level reference data model of most commonly reused descriptors for a digital object 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.
