First Talk – XML data: Find with XQuery, Validate with Schematron by Andy Zhang: Since the early and mid 1990s, XML implementations and usage have been skyrocketed. This presentation will be focus on two powerful XML related technologies–XQuery and Schematron.

XQuery is a powerful functional programming language. In a nutshell, it composed of expressions. During the first part of this presentation, you will have chance to see some expression in action. Schematron is an XML vocabulary that often used for QA and validation. We will look at how to use Schematron for testing with Assert and Report.

First Speaker: Andy Zhang is a lead application architect. He has a Master’s degree in Computer Information Systems and numerous industry-recognized certifications. He has helped several Fortune 500 companies to plan, develop, test, and implement enterprise systems. His publications have been appeared on premier software journals such as MSDN online. He is the author of Beginning XQuery and Beginning MarkLogic.

Second Talk – Forking Another JVM to Do Your Dirty Work by Tom Grant: This talk will discuss some of the benefits and challenges of launching external JVMs to perform long-running tasks. Starting a separate JVM process provides isolation of memory, security, and classpath and can be extended to take advantage of multiple processors and multiple machines within a cluster. Tom will examine situations where this approach is appropriate and demonstrate the source code for dealing with those challenges.

Second Speaker: Tom Grant is the Product Manager and lead architect for the Twister Data Framework, a software suite offered by Solutions Made Simple, Inc. for building data management applications. Tom has been building back-office, data centric systems in the Java language since 1999.
