ESSArch

ESSArch is based on OAIS (Open Archival Information System, ISO 14721:2003) and further on developed to include both PreIngest and PreAccess functions, Storage Methodes and flexibility to add any metadata standard required. The main conceptual functions are based on traditional archiving preservation processes.

Supported specifications

ESSArch supports the specifications used by the National Archives of Sweden (FGS) and Norway we also have strong support for the EARK-specifications which we also have contributed to.

  • Pre-Ingest
    PreIngest is the function used to prepare packages for delivery according to Submission Agreement. Unstructured information becomes structured.
  • Ingest
    Ingest provides services for receiving submission information packages (SIP), quality checks and preparation for delivery of archival information packages (AIP) to storage infrastratucture.
  • Archival Storage
    ESSArch offers the possibility to use multiple storage methods and supports different storage technology for example Disk, Tape and S3.
  • Data management
    ESSArch offers a complete solutions for archival collections management. It adheres to ICA standards (ISAAR-CPF, ISAD-G, ISDF) and has functionality for managing accessions, locations, classifications and preservation planning of archival holdings.
  • Access
    Access provides services for receiving and resolving inquiries from Consumers. It fetches Archival Information Packages (AIP) and creates Dissemination Information Packages (DIP) if required and performes quality checks before delivery to PreAccess function.

Pre-Ingest

Submission agreement negotiations

The first mandatory responsibility as stated in the OAIS reference model is to negotiate for and accept appropriate information from information Producers. This is done by the means of a Submission Agreement: The agreement reached between an OAIS(Archive) and the Producer that specifies a data model, and any other arrangements needed, for the Data Submission Session. This data model identifies format/contents and the logical constructs used by the Producer and how they are represented on each media delivery or in a telecommunication session.

Though the OAIS reference model acknowledge the need of a submission agreement to be drawn up between the producer and the archive the model does not describe this in detail. There is however a seperate methodology to help define and provide structure to the relationships and interactions between an information Producer and an Archive. The Producer Archive Interface Methodology Abstract Standard (PAIMAS) that defines the methodology for the structure of actions that are required from the initial time of contact between the Producer and the Archive until the objects of information are received and validated by the Archive

The "output" from working with the PAIMAS methodology are agreements for preservation principles, technical tolerances, package structures, processes and regulations. It also identifies, defines and quantifies organisational needs as well as how everything should be financed.

Data Extraction

The actual data extraction of data/records/files as required by the Data Selection Profile defined in the agreement processesing. Depending on the prerequisites of the source-system this process can be a cumbersome and often involve unforeseen costs especially when dealing with data extraction from legacy it-systems.

Prepare-IP

The first step in the process of SIP creation is the Preparation of an Information Package. Whitin ESSArch, the system prepares the IP:s on a logical and physical level. The producer prepares the Package Description and selects the appropriate predefined profiles.

DEMO!

Create SIP

The SIP:s are created, based on the submission agreement and its associated profiles.

DEMO!

(S)IP Validation

The SIP is validated before submitting to the receiving organzation (archive). It is checked for integrity, syntax and format according to what was decided in the Submission Agreement.

DEMO!

Submit SIP

The SIP is prepared for submission and submitted to the receiving archive. ESSArch Supports both submissions from the same instance as well as from remote instances.
