OAISviitemalliin

OAISviitemalliin refers to a framework for describing and organizing digital objects, specifically in the context of digital preservation and long-term access. OAIS stands for Open Archival Information System.

Developed by CCSDS (Consultative Committee for Space Data Systems), OAIS is a reference model that outlines the functions and components necessary for a digital repository to preserve digital objects over time. The OAIS framework emphasizes the importance of ensuring that digital objects can be accessed and understood by future generations, despite changes in technology and infrastructure.

At its core, OAISviitemalliin involves the five primary functions of an OAIS:

* Ingest: Collecting and accepting digital objects into the repository

* Verify: Confirming that digital objects are complete and accurate

* Storage: Preserving digital objects in a non-proprietary format

* Retrieval: Providing access to digital objects when requested

* Access: Offering services for searching, retrieving, and interpreting digital objects

The OAISviitemalliin also includes a range of key components, including the information model, which describes the structure and relationships between digital objects. Key characteristics of OAIS include robust preservation, long-term viability, and technological independence.

Effectively implementing OAISviitemalliin requires coordination and standardization between various stakeholders, including digital repository managers and preservation experts. Organizations that adhere to the OAIS framework can ensure that digital artifacts are maintained in a way that ensures their long-term accessibility and usability.
