The WSO2 Governance Registry (G-Reg) is a SOA-integrated registry-repository for storing and managing data or metadata related to service artifacts and other artifacts. It provides a rich set of features including SOA governance, lifecycle management, and a strong framework for governing anything. For more information on the features and functionality of WSO2 Governance Registry, go to WSO2 Governance Registry.
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.
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, and 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.
