An entity is an object about which an information system collects data. ICA-AtoM's architecture include a number of entity types, but from the user's point of view there are four main types with which they will interact:
Archival descriptions
- Provide contextual information about archival materials.
- Are aranged into hierarchical levels (fonds, series, files, items).
- Include data elements based on the ICA's General International Standard Archival Description (ISAD-G).
Authority records (actors)
- Provide descriptions of the actors (corporate bodies, persons and families) that interact with archival materials as creators, custodians, subject access points, etc.
- Include data elements based on the ICA's International Standard Archival Authority Records (Corporate bodies, Persons, Families) (ISAAR(CPF)).
Archival institutions
- Provide descriptions of repositories that preserve and provide access to archival materials.
- Include data elements based on the ICA's International Standard for Describing Institutions with Archival Holdings (ISDIAH).
Terms
- Provide controlled vocabularies used throughout the system (e.g. as access points or in drop-down value lists).
- Are organized into separate taxonomies.
- Include minimal data elements; a future iteration of ICA-AtoM will extend one such taxonomy ("Function description") to include the elements found in the ICA's International Standard For Describing Functions (RS-4|ISDF).
Actors (corporate bodies, persons, families) are described in ISAAR(CPF) authority records. Actors can be creators, custodians and subjects of the material described in archival descriptions. These relationships are registered as ICA-AtoM events delimited by start / end dates. Through events, 1 actor can have 0, 1 or many relationships to 0, 1 or many archival materials; and 1 archival unit can have 0, 1 or many relationships to 0, 1 or many actors. Event relationships link ISAAR authority files (descriptions of actors) and ISAD records (descriptions of archival materials).
An archival institution is an actor that holds archival materials. Like all actors, it has its own ISAAR authority record. But its characteristics as a repository (e.g. its opening hours, research services, contact information) are described separately in an ISDIAH institution record. The ISDIAH elements that are inherited from its ISAAR authority record are:
- Authorized form of name
- Other forms of name
- Parallel forms of name
- History
- Mandates/Sources of Authority
- Administrative structure
