The WSO2 Governance Registry is a fully open source, SOA-integrated registry-repository for storing and managing metadata related to service artifacts and other artifacts. WSO2 Governance Registry is fully open source and is released under Apache Software License Version 2.0, one of the most business-friendly licenses available today. 

Eschewing the complexity (and WS-* focus) of specs like UDDI, the Governance Registry uses Atom Publishing Protocol (via Apache Abdera) to offer a standard and simple RESTful remote interface, which can be accessed easily by custom code, feed readers, and browsers. It has been designed to both encourage "grass-roots" community around your data and also to allow for IT-friendly governance.

The WSO2 Governance Registry is an on-going project. It undergoes continuous improvements and enhancements with each new release, to address new business challenges and customer expectations. WSO2 invites users, developers and enthusiasts to get involved or get the assistance from our development teams at many different levels through online forums, mailing lists and support options. We are committed to ensure you a fulfilling user experience at any level of involvement with the WSO2 Governance Registry. 

You can use WSO2 Governance Registry either as a complete product or in combination with components of other WSO2 products. User-specific components, extensions or UIs to the Registry can be easily added as Carbon components.

Artifacts

There are two broad categories of artifacts found in the WSO2 Governance Registry as follows.

Resources

 A resource is any artifact from WSDL files to XML, Word/Excel documents, JPEG Images, etc. Every resource in the WSO2 Governance Registry becomes a center for social activity.

Collections

 A collection is a group of resources that falls under a logical entity, and are stored within WSO2 Governance Registry. 

Main functionality

WSO2 Governance Registry main functionality falls under the following two categories.

Content repository

The content repository virtually can hold any type of content. But in order to give prominent support for SOA-type services, it is cased as follows:

  • Special UI to capture both technical and non-technical details related to the services
  • Separate upload UI's for Policy, WSDL and Schema, which are tightly related to SOA type services
  • Built-in validation for Policy, WSDL and Schema

Governance framework

The governance framework embodies the following set of governance features which allows you to govern the artifacts stored in the content repository.

  • Define any type of governance asset
  • Customizable repository extension points, executable via manual intervention (aspects) and by the framework (handlers) along with relevant evaluation criteria (filters)
  • Integrated with 3rd party products and external systems
  • Repository APIs: JCR
  • Registry APIs: REST, UDDIv3, JAXR
  • Governance APIs: REST, Atom/AtomPP, SOAP
  • Centrally integrated with the latest version of WSO2 Enterprise Store 2.0 and WSO2 API Manager
  • Create and manage registry resources, APIs and Swagger instances with the newly introduced Governance Centre UI
  • Installation provision for API-M, enabling API publisher and store functionalities, including API creation, publishing, subscription, token generation and regeneration within WSO2 Governance Registry
  • Graphical differentiation view to compare two inter-related assets
  • New asset association UIs and extension point to perform add/remove associations based activities
  • Improved extension points to write tasks based on registry API and governance API

Updating service details

Service resources are stored within /governance/services. Monitoring/querying of the location /governance/services gives vision of the services registered within Governance Registry. Another option is to enable notifications (e-mail, SOAP, HTTP POST) for this repository location. For advanced users, Governance Registry supports writing custom handlers for given media types. 

 There are two ways to update the Governance Registry with service details as follows.

Using Governance Registry's UI

If you choose the first way and add a service bearing the name "OrderRegistration" with the namespace as org.acme.services, a resource will be created inside /governance/services/org/acme/services/OrderRegistration with application/vnd.wso2-service+xml as the media type. 

Uploading WSDL

Similarly, you can upload a WSDL to the system and Governance Registry will automatically create a service resource under /governance/services collection. Additionally, if a given service has WSDLs/Schema/policies, Governance Registry will automatically upload them and create associations between related artifacts(resources).
