Enabling a Multi-channel Content Strategy

ContentServices SDK is a Web services-based development kit that enables enterprises to rapidly integrate content management (CM) into any application. Web services architecture takes the best features of a Service-Oriented Architecture (SOA) and combines them with the Web.

Evolution of Service-Oriented Architecture (SOA)

SOAs have evolved over the last 10 years to support high performance, scalability, reliability, and availability. In a SOA, applications are designed as services that run on a cluster of centralized app servers. In the past, clients accessed these services using protocols such as DCOM, CORBA or RMI. While effective for building a specific application, they limit the flexibility of the system and the reusability of individual services. Each of the protocols is inhibited by dependencies on vendor implementations, platforms, languages, etc. that limit interoperability, and none of these protocols operate efficiently over the Web.

Using Web Services to implement a SOA

A Web service is an application that can be accessed using standard Web protocols. Any type of application can be offered as a Web service, whether running on the Internet, intranet or extranet.

Web services provide functionality that can be easily reused without knowing how the service is implemented. They are accessed via commonly used Web protocols and standards, such as HTTP & TCP/IP, and using universally accepted data formats, such as XML. Web protocols are vendor-, platform-, and language-independent, removing the limitations of DCOM, CORBA or RMI. Three XML-based technologies are emerging as the de-facto standard for Web services:

• Simple Object Access Protocol (SOAP): a standard communications protocol for Web services
• Web services Description Language (WSDL: a standard for describing a Web service
• Universal Description Discovery & Integration (UDDI): a standard way to register and locate Web services

Integrate Content Management Into Any Application

ContentServices SDK exposes Interwoven content management services such as file system, access control, and workflow, and hundreds of methods and classes. It utilizes industry standards, such as XML, SOAP and WSDL, enabling developers to use the platform and tool of choice. ContentServices SDK ships with a number of WSDLs, a Java convenience library, and a Developer's Guide that provides sample code to help developers get started.

Interwoven embeds the industry's leading SOAP server, Systinet WASP, into ContentServices SDK. There are some excellent white papers on SOA architecture and SOAP services on the Systinet Web site. To download, go to the Systinet Resources Page.
