data.all vs Liberbyte Data Exchange

data.all is an open-source platform for managing and discovering data assets in AWS accounts. Its central catalog inventories datasets, tables, folders, and dashboards, with filters for asset type, tags, region, and glossary terms. Datasets can contain structured tables or unstructured folders and use AWS S3, KMS, IAM, and Glue resources. Teams can share datasets between environments by granting selected roles read access through Lake Formation without moving data. The catalog imports tables from Redshift Serverless and provisioned clusters. Analytics options include Athena worksheets, SageMaker Studio access, Jupyter notebooks, and QuickSight dashboards. Administrators manage teams and users across environments. Authentication supports Cognito federation with a corporate identity provider or an external OIDC provider. Deployments may face the internet or remain inside a VPC. AWS setup requires at least two matching-region accounts and administrator credentials.

Liberbyte Data Exchange, delivered as bytEM, is a federated implementation of the OUDEA data exchange architecture. It is designed to let organizations identify, discover, reference, resolve, and exchange governed data entities across independent systems without requiring a central data platform. The workflow is Search → Find → Exchange, with references connecting related entities. The architecture supports indexing entities, resolving current access, and transferring governed data. Liberbyte describes its data management approach as combining governance and business requirements through metadata and flexible processing, and 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 first public bytEM instance and live data index is cities.app; environment.app and legalentities.app are available through cooperation rather than unrestricted public access. 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. Pricing is on request.
