Archivematica uses a micro-services design pattern to provide an integrated suite of free and open-source tools that allows users to process digital objects from ingest to access in compliance with the ISO-OAIS functional model. Archivematica implements media type preservation plans based on an analysis of the significant characteristics of file formats.  Where did Archivematica come from?   Artefactual Systems    City of Vancouver Archives    UNESCO Memory of the World    International Monetary Fund Archives    Rockefeller Archive Center    University of British Columbia Library    Simon Fraser University Archives    ?  PODS: Permanent Objects, Disposable Systems             Pile o' stuff gets accessioned by an archives The archivist appraises, organizes, adds descriptive metadata, makes a nice Submission Information Package (SIP) The SIP is ingested into Archivematica Archivematica creates a package which includes the original objects, any normalized versions, and large quantities of descriptive, technical and preservation metadata: the Archival Information Package (AIP) The AIP conforms to international standards, is self-contained and interoperable – a permanent object which can be managed in Archivematica or another disposable system Archivematica creates a Dissemination Information Package (DIP) for upload into the access system  ICA-AtoM         The DIP gets uploaded to ICA-AtoM ICA-AtoM: International Council on Archives: Access to Memory The archivist enhances descriptive metadata as needed The digital objects are displayed with their descriptive metadata in the context of a hierarchical archival arrangement  Attribution Title: Open-source software for archives: Archivematica and ICA-AtoM Creator: Evelyn McLellan, Artefactual Systems Inc.
