The WSO2 Governance Registry (G-Reg) is an SOA-integrated registry-repository for storing and managing data or metadata related to services and other artifacts. It consists of two Web-based interfaces: the G-Reg Publisher and G-Reg Store. The Publisher is used to create and manage assets, while the Store is used to search for and subscribe to assets.

Introducing the sample
BuyMore is a fictitious supermarket chain with more than 200 retail branches. Given below is a snapshot of the existing services of BuyMore with their lifecycle states:
...
- Log in to the G-Reg Store (https://localhost:9443/store/) as Smith. Smith's credentials are smith/smith@bm.
- Click Rest Services in the left menu.
Search for the asset by typing "name:BuyMoreBillCalculateRESTAPI" in the search field and clicking the search icon.
Notice that many services are shown in the search results. Smith knows that the service he wants (i.e.,BuyMoreBillCalculateRESTAPI version 1.0.0) is is owned by the Think Tank team in Boston and is hosted by the Vancouver Boston data center, so he filters the search by those criteria to make sure he finds the right one. - Expand the the Teams filter filter in the the Filter by menu menu, expand the the Boston menu menu, and click the icon with the plus sign next to to Think Tank to to select it.
- Expand the DataCenters filter in the Filter by menu, and click the icon with the plus sign next to Vancouver to Boston to select it.
- The service
BuyMoreBillCalculateRESTAPIversion 1.0.0appears in the search results. Click it to open it.

Smith has now discovered the REST asset that can be called from other applications to calculate bill values. Next, Smith subscribes to receive notifications for this asset.
