Membership Levels


Sustaining Members provide leadership for the Cooperative through the MetaArchive Steering Committee (comprised of one representative per Member). As leaders in the field of distributed preservation practices, these members are involved in testing and development and maintenance of hardware and software. They also help set the standards for network connectivity and transmission.


Preservation Members engage in ongoing preservation activities and participate in the network by either maintaining a MetaArchive-LOCKSS cache, or paying an annual technology fee as alternative to cache hosting.


Collaborative Members are bands of institutions that look and act like one unified member because they share a central server. This level of membership is designed to allow new or existing consortia or collaborative organizations to preserve their co-hosted content for a fraction of what it would cost to do so as individual members.

How do I get my collections into MetaArchive?

You simply produce a short descriptive entry in the MetaArchive Conspectus interface, describing the collection(s) your are submitting for ingest and submitting the package(s) of content that you have prepared. These package(s) are tested in the MetaArchive test network to ensure that they are ready for full ingest. Once tested and approved, the network administrator selects seven secure, closed-access nodes on the network to receive the content for preservation. Each of the seven systems administrators who manage those seven nodes ingests the content and records the successful completion of that ingest. Once ingested, the content is monitored iteratively for bit integrity.

How do I get my collections out of MetaArchive?

If you lose your local collection copies for any reason, a copy can be easily obtained from the network. You simply request a copy from the MetaArchive network administrator. An uncompressed BagIt package will be constructed and made available for download.

Can I be sure that no one will have unauthorized access to our collections?

The MetaArchive network is a secure, dark archive. No one is permitted to access any member’s stored collections except when a copy is requested by the owner to replace a lost or damaged local copy.

What type of file formats does MetaArchive allow? Are there any formats that are prohibited?

The MetaArchive accepts all formats and does not require a member to transform or normalize their content prior to ingest. If a member has a concern about a format type and its risk of obsolescence they can consult resources produced by the MetaArchive Preservation and Content Committees to assist with assessing the risk and offer recommendations.

Do I need to have an institutional repository in order to get started?

No, it is not necessary for you to have an institutional repository. That being said, the MetaArchive regularly preserves collections from many of the leading institutional repository systems in use, including Fedora, Samvera, DSpace, DigiTool, Digital Commons, and Islandora.

What are the technology requirements for MetaArchive?

The MetaArchive provides a full description of its technology requirements in its annual Technical Specifications.

Is the MetaArchive Cooperative currently accepting new members?

Yes, the MetaArchive is currently accepting new members from a wide variety of organizational types, including libraries, archives, historical societies, research centers, foundations, and other digital memory organizations.
