Abstract:

The xlinkit Rule Workbench, due for release in early October 2004, is Systemwire's flagship product for semantic validation of XML documents against business rules. Rules are expressed in the CLiX (http://www.clixml.org) language, which is represented in XML and provides a simple, declarative and extensible means of constraining documents.

The xlinkit Rule Workbench provides support for both intra-document validation and cross-document rules. This enables users to check multiple XML documents against one another and, using the included database adapters, against corporate reference databases. Extensions scripted in ECMAScript can be used for further integration, for example by querying Web Services during validation.

In this demonstration, XML users, vendors, and parties interested in building xlinkit into their products will learn how:

- Validation rules are usually discovered

- Rules are constructed using the workbench

- The workbench's XPath editor uses a "point and click" interface to

remove the usual pain of having to write and test XPath expressions

- Complex validation operations are performed using extensions written in

ECMAScript

- Rules are tested using impact analysis

- Batches of documents are quickly schema and rule-validated

- The workbench integrates into the open "eclipse" platform

The demonstration will use Financial Products Markup Language (FpML) documents as examples. The rules we will show will be self-explanatory and can apply to many other types of XML languages, no prior knowledge is necessary.
