The MICHAEL Data Model

• the entity Institution, which provides a concise description of the organization responsible for the development or maintenance of the collection, with its name, acronym, addressand contact information, in addition to information on whether the organization is public or private; finally, the organization institutional type and jurisdictional information are indexed;
• the entity Service/Product, which describes the supports (website, DVD, CD-Rom, or other) through which the digital collection can be accessed and consulted. The Service/Product records provide the necessary technical details for identifying and accessing the online service, or for accessing the offline product containing or making available the digital collection to which the description is linked;
• the entity Project/Programme, which provides the right place for the registration of information related to the context within which the digital collection was put together: funding resources, the span of time during which it was carried out, whether the digitisation project was carried out using original physical items or intermediate analogical formats, and so on;
• finally, the entity Physical Collection makes it possible to link digital collections to digitized physical collections in all those cases in which the digital collection is the outcome of the systematic digitisation of one or more physical collection, or of the main part of a single physical collection.
