-The web dashboard allow users to process, monitor and control the Archivematica workflow processes. It is developed using Python-based Django MVC framework. The Dashboard provides a multi-user interface that will report on the status of system events and make it simpler to control and trigger specific micro-services. This interface allows users to easily add or edit metadata, coordinate AIP and DIP storage and provide preservation planning information. Notifications include error reports, monitoring of MCP tasks and manual approvals in the workflow. In coming releases, the dashboard will support a transfer backlog linked to accession data as well as indexing, analysis, arrangement and minimal description of transfer(s) into SIP(s). An administration area allows users to manage storage locations, configuration of micro-services, alteration of preservation plans and user access levels.

 Digital preservation systems must implement strategies that deal with technology obsolescence and incompatibility to ensure that digital objects remain authentic, accessible and useable for future use. The technologies that create digital objects and the technology available to manage them are constantly changing. Therefore, the Archivematica project has established an [[wikipedia:Agile software development|agile software development]] methodology to manage the perpetual maintenance and development of the system. This methodology is focused on rapid, iterative release cycles, each of which improves upon the system's [[Technical_Architecture|architecture]], [[requirements]], [[External_tools|tools]], [[documentation]], and [[development]] resources.

 ==From Transfer to SIP to AIP and DIP==
 The primary function of Archivematica is to process digital transfers (accessioned digital objects), turn them into Submission Information Packages (SIPs), apply format policies and create high-quality, repository-independent Archival Information Packages (AIP) using [http://www.loc.gov/standards/mets/ METS], [http://www.loc.gov/standards/premis/ PREMIS] and [https://confluence.ucop.edu/download/attachments/16744580/BagItSpec.pdf?version=1 Bagit]. Archivematica is bundled with AtoM, but is designed to upload Dissemination Information Packages (DIP), containing descriptive metadata and web-ready access copies, to several access systems (e.g. Dspace, ContentDM, etc.).

All of the Archivematica code and documentation is released under AGPL and Creative Commons open-source licenses.
 ==Micro-Services design pattern==
 Archivematica implements a [http://www.cdlib.org/services/uc3/curation/ micro-service] approach to digital preservation. The Archivematica micro-services are granular system tasks which operate on a conceptual entity that is equivalent to an OAIS information package: Submission Information Package (SIP), Archival Information Package (AIP), Dissemination Information Package (DIP). The physical structure of an information package will include files, checksums, logs, submission documentation, XML metadata, etc..
-These information packages are processed using a series of micro-services. Micro-services are provided by a combination of Archivematica Python scripts and one or more of the free, open-source [[External tools|software tools]] bundled in the Archivematica system. Each micro-service results in a success or error state and the information package is processed accordingly by the next micro-service. There are a variety of mechanisms used to connect the various micro-services together into complex, custom workflows. Resulting in a complete ingest to access system.
