Liberbyte Data Exchange
What Liberbyte Data Exchange is
Liberbyte Data Exchange is Liberbyte’s federated implementation of the OUDEA data exchange architecture, called bytEM. It is intended to let independently governed data entities be identified, discovered, referenced, resolved, and exchanged across systems without requiring a central data platform. The workflow is Search → Find → Exchange, with references connecting related entities. The architecture supports indexing entities, linking related entities, resolving current access, and transferring governed data. Liberbyte describes its data management approach as bringing governance and business requirements together through metadata and flexible processing. It presents controlled publication and exchange as a way to create data products and commercial data services. OUDEA v0.1 uses Matrix federation as its initial protocol substrate, and the public installer includes Matrix Synapse. The public installer repository is under AGPL-3.0 and requires a Linux host with Docker Engine and the docker compose plugin. The bytEM core is privately maintained, with source access available by request under a cooperation agreement. cities.app is the first public bytEM instance and live data index; environment.app and legalentities.app are available through cooperation rather than unrestricted public access. Pricing is on request.
Who it suits
Liberbyte presents bytEM for organizations seeking governed data exchange across organizational boundaries, including research partners and data index operators. It may suit teams prepared to discuss deployment cooperation or request core source access.
What it does well
- Designed to exchange governed data without a central data platform.
- Workflow connects search, discovery, and exchange.
- Public installer repository is under AGPL-3.0.
- cities.app is a public instance and live data index.
- Supports access controls and private marketplaces.
What to know first
- Installer requires Linux, Docker Engine, and the docker compose plugin.
- bytEM core source is privately maintained.
- Core source access requires a cooperation agreement.
- Some indexes are available through cooperation, not unrestricted public access.
Limits
Pricing is on request. The public installer is available under AGPL-3.0, but the bytEM core is privately maintained and its source access can be requested under a cooperation agreement. The environment.app and legalentities.app data services are available through cooperation.
Getting started
- Visit the Liberbyte website to discuss product details or request a demonstration.
- Request pricing and discuss a cooperation agreement if you need bytEM core source access or cooperation-only data services.
- Prepare a Linux host with Docker Engine and the docker compose plugin.
- Use Liberbyte’s public bytEM installer repository, which includes Matrix Synapse.
Verdict
Liberbyte Data Exchange focuses on federated, governed data discovery and exchange rather than a central repository. Organizations should account for the private core and cooperation-based access to some indexes when considering implementation.
