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



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).
