OTUG: The Object Technology User Group; St Paul/Minneapolis, Minnesota

The Object Technology User Group

OTUG is an umbrella user group spanning languages, methods, tools, and technologies for the software development community in the Minneapolis - St. Paul area.

OTUG exists to foster an environment for professional discussion and education pertaining to software development ecosystems; i.e., software development organizations and the contexts in which they operate.

Meetings are generally held on the third Tuesday of each month and are a mix of general and special interest discussion, open space, fishbowl and panel sessions, with periodic presentations by featured speakers.

Meetings are open to anyone with an interest in software development. You become a "member" simply by attending and participating. OTUG is a volunteer organization and we welcome your active involvement.

XRX Architecture*

* XForms, ReST, and XQuery

Date: Tuesday, October 21, 2008

Time: 5:30 - 9:00 PM

Location: University of Saint Thomas, St. Paul Campus

University of St. Thomas, St. Paul, MN

No RSVP needed. McNeely Hall Room 238

The XRX Web Application Architecture - XRX is a new web application architecture that uses XForms on client, ReST web interfaces and XQuery on the server. XRX uses a declarative style of programming that allows complex rich-client applications to be created quickly with little or no procedural coding. XRX is frequently described as an elegant minimalist architecture since XML structures are used on both the client and in the persistence layers with no translation. This makes it an ideal system in which to integrate XML rules processing services. On the client side, XRX architecture leverages w3c standards, advanced MVC architectures in the web client, an efficient dependency graph and as-you-type data validation. On the server side XRX provides easy-to-create XML and XHTML web services to support all aspects of complex web processing.

This presentation will give an overview of the XRX architecture and the design patterns it encourages. We will also compare and contrast XRX with similar advanced web application architectures and then present two case studies of its use in the Twin Cities area including complex forms management and metadata management systems.
