Tipos de entidades

Main Page > (UM) User manual > UM-1 System overview > UM-1.3 Tipos de entidades

Una entidad es un objeto sobre el que almacena datos un sistema de información. La arquitectura del ICA-AtoM's incluye un número importante de tipos de entidad, pero desde el punto de vista del usuario final hay cuatro tipos principales que son con los que interactuará:

• Descripción Archivística

• Registros de Autoridad (actores)

• Instituciones Archivísticas

• Términos

Core entities and their relationships

Descripción Archivística

• Proporciona información contextual sobre los materiales de archivo.

• Está organizada en niveles jerárquicos (fondos, series, expedientes, documentos).

• Incluye campos basados en los estándares internacionales de descri`pción archivística RS-1 e ISAD-G'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)).

• Are linked to archival descriptions in ICA-AtoM by events delimited by start / end dates. Through events, 1 actor can have 0, 1 or many relationships to 0, 1 or many archival units; 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).

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).

• Are actors that hold archival materials. Like all actors, an archival institution 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, and Administrative structure.

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 (ISDF).
