Description:

The digital viual object reference data model provides a list of standard fields that are typically present in the general description of a digital images in a cultural heritage data system. A digital visual 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 visual objects are often stored as reference or documentation objects relative to cultural heritage items such as the scanned pages which serve as the input for OCR processes. Digital visual 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. 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 viual 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.
