The WS-Policy specification provides a simple language for expressing
policies supported by Web services. IBM WebSphere Service Registry and Repository
supports loading, changing, and retrieving policy documents, and also supports
using policy attachments to link a given policy with a service. This can then be
used by a run time component, like an Enterprise Service Bus, to retrieve
defined policies for a particular service or operation and act accordingly.
This article shows how you can utilize standard WS-Policy documents stored in a
registry to impact run time behavior in an ESB — and then change that behavior
on the fly with no code changes or redeployment. (IBM WebSphere Developer Technical Journal)

Create classification taxonomies programmatically in IBM WebSphere Service Registry and Repository
By creating classification taxonomies in IBM WebSphere Service Registry
and Repository, you can flexibly catalog and organize services and your metadata,
enabling effective governance. This article illustrates a mechanism for
uploading classification taxonomies into the WebSphere Service Registry
and Repository using an XML-based interface, which can also be extended as an
integration mechanism for synchronizing classification taxonomies to WebSphere
Service Registry and Repository from other external systems. Find out how to load the
classification taxonomies into WebSphere Service Registry and
Repository using the Java Management Extensions (JMX) management APIs provided by WebSphere Service
Registry and Repository.
Using DataPower SOA Appliances to query WebSphere Service Registry and Repository
Learn how to use IBM WebSphere DataPower SOA Appliances to query information from IBM WebSphere Service Registry and Repository using the REST API and SOAP API. Reusable stylesheets are provided to serve as standard query components to be used throughout DataPower configurations. Step-by-step examples show how these assets can be used to query WebSphere Service Registry and Repository. (IBM WebSphere Developer Technical Journal)
WSDL Anti-Pattern: The ‘Single XML String’ Service
WSDL is a very useful technology. It allows service providers and consumers to agree on namespaces, operation names, the data to be transmitted in a request and the data to expect in a response. All very good things to know, all in a platform neutral way. Now, WSDL tells us what all the elements and […]
