Runtime governance comes into play, soon after the service is deployed. It monitors operational aspects of a service (service performance bottle necks, who is accessing more, etc.). Unlike design-time governance, most runtime governance functions are automated. Reports generated in this phase are important feedback, for the next service design and development iteration.

Registries and Repositories
To enable SOA governance, software industry responded with two different categories of tools:
...
- Record information on services
- Search for an existing service for reuse
- Discover associations and dependencies of a service
- Enforce policies throughout the service lifecycle
- User access control
- Automatic version control
- An SDK for registry-repository extensibility

Governance Registry components
A component is made up of one or more OSGi bundles. A bundle is the modularization unit in OSGi, similar to a JAR file in Java. The component-based architecture of all WSO2 products gives developers flexibility to remove or add features with minimum dependencies.
The Governance Registry comprises of the following high-level components:
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
Assets
WSO2 Governance Registry stores governance metadata and information on governance related entities. Registry resources storing this information and/or metadata are known as assets. With Service metadata, you can import most of the information which is separately stored in the WEB in to the Governance Registry, and manage them as Governance Registry Resources.
...
WSO2 Governance Registry facilitates two types of assets: in-built and custom. For more information on these assets, see Adding Assets.
...
Categorizing assets
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.
...
Publishing assets
The WSO2 Governance Registry allows you to add services through its Web-based user interface. User can choose either to enter service details manually or to import service information using a WSDL url. For more information see Governance Artifact Configurations.
...
Resources for service discovering tremendously help in service reuse. In fact, it is one of the major functions of a registry-repository product. The WSO2 Governance Registry provides enhanced search capabilities to facilitate search based on tags and other advanced criteria. See also Resources.
