The record

Purpose: Open Integration Hub is an open source framework for synchronizing data between business applications.
Hub model: The hub model uses one connector to the framework instead of separate connectors for each application.
Framework components: The framework includes authorization, validation, routing, central data storage, standard data models, metadata storage, and connectors.
Connector format: Connectors translate incoming formats such as XML or CSV into JSON and can define integration actions and triggers.
Data mapping: Connectors use transformers to map data schemas to standard data models, and the site suggests JSONata.
Connector ecosystem: Connectors can be built for any solution, published as open source, and distributed as Docker containers.
Ready made platforms: The site identifies Basaas and elastic.io as platforms built on or implementing the framework.
Embedded integrations: The platform page describes an embeddable integration catalog and an API for custom implementation.
Flow management: The platform page says users can manage integration flows and create flow templates in a backend.
Customization limit: Using the main scenario gives the highest standardization and automation but limits custom data fields and components.
Alternative scenario limit: Without standard data models and the Smart Data Framework, data must be mapped manually and standard connectors cannot be used.
License and security: The framework components are published under Apache 2.0, which the site says permits commercial use; the pages reviewed do not specify security certifications.
Support: Connected and Integration memberships include basic developer support, while Enterprise and Strategic memberships include advanced developer support.
Intended users: The site describes use by software vendors, platform providers, system integrators, and internal IT departments.
