Products Explore our open source digital preservation toolset

We maintain a number of open source digital preservation products which form the OPF reference toolset. Our toolset addresses common issues faced by many organisations and we provide a mechanism to focus effort and resources into effective solutions. Our current products are mainly used in the pre-ingest and ingest stages of preservation, but our toolset is constantly evolving in response to the needs of our members.

Our products are widely adopted by the community, and can be used as stand-alone tools, as part of a bespoke digital preservation workflow, or can be found embedded in several leading commercial solutions.

As an experienced leader in open source development, we believe that making our products available under open source licences helps to support their long term sustainability. Not only does this approach help people to better understand the software they are using and adapt it to their requirements, it helps to ensure that our products are thoroughly tested by a community of practitioners.

The products in our reference toolset are mature and ready for use in production environments and workflows. To learn more about our participation in research and development projects, take a look at what we’re working on.

If you use our products, please consider becoming an OPF member or making a donation to support our work.

Our products

The products below are the core components of our reference toolset which are maintained under our product release cycle. We also provide hosting for prototypes (which you can explore on GitHub) and participate in selected research and development projects.

Our product release cycle

Every product in the OPF reference toolset undergoes a regular triage session where the OPF team and tool maintainers meet to review the list of issues raised on GitHub. During this process, each issue is categorised as a bug or feature, assigned a priority level, and given an estimated number of development days. Together, we agree a set of work and associated milestones for the upcoming releases and present them to our product board for review and approval at the next meeting.

OPF product release cycle


This process is designed to help users plan for adopting new software updates into their workflow as well as identify priorities for contributors or for our community hack weeks.

Release schedule

Typically, we aim for one new release of each product per calendar year. Our provisional release schedule for the current year is below.

Product Board

The OPF product board is a select group of our members who govern the roadmap for the reference toolset. They meet every two months to approve our development priorities, give feedback on strategic changes and influence the adoption of new tools. 

To help ensure that our members’ needs are well-represented and prioritised, it is important that this group reflects the organisational diversity of our membership. The product board currently comprises representatives from libraries, archives, and software providers from around the world.
