Open Integration Hub



Connector Guidelines

The Open Integration Hub enables data synchronization across a variety of applications. To enable interaction with any software an technical component is needed to the Open Integration Hub - the connector. It consists of two distinct parts: the adapter and the transformer.

An adapter is a module for the syntactic connection of an external application and its data to the Open Integration Hub. This includes protocol translation, data format transformation, etc. Furthermore it provides functionalities to perform e.g. CRUD operations within the source system.

A transformer is responsible to semantically transform an incoming JSON object into another JSON object. Thus the mapping between two data models is done within the transformer.

The following illustration provides a holistic overview of a connector: Connector

Open Source Connectors

Like the Open Integration Hub services, connectors are also standardized components that can be reused in any implementation of the framework. There are several contributors that provide a wide range of open source connectors already. So before you start your own, check out what’s already there:

If you want to build your own connector, we suggest you start with a our node.js example, to understand the structure and what you need to get going. Most components are build in node.js, although you can choose any language you want.

If you prefer a real world example, the wice components are good place to get inspiration.
