ArchStudio is an integrated set of architectural analysis and composition tools. Currently, we are working on creating ArchStudio 3 which will integate xADL 2.0 and a number of features from Java JDK 1.3. (Note, this site is password protected, but I can send you both upon request.)

Information about the old (1999-ish) ArchStudio 2.0 system and demo can be found on the Software Architecure Website.

Chimera 2.0

Chimera is an open hypermedia system deeply integrated with the WWW. Chimera is designed to allow different applications to be linked in a hyper-web through an API which stores the linking information seperately from the underlying data source (commonly known as a link server hypertext approach). This means that applications (i.e. legacy systems) that weren't designed as either hyper-text enabled systems or Web enabled systems can actually be linked together by using Chimera. This has been demostraited by Northrop-Gruman's Military Aircraft Division which linked the B-2 simulation environment to software requirement artifacts which allowed for simulated in-flight mission parameter changes.

Chimera's servers are being actively developed at the University of Colorado, Boulder under the investigations of Ken Anderson, while Chimera client integrations are being developed here at UCI.

WebDAV is an widely used IETF standard. It extends the HTTP 1.1 Protocol to enable distributed authoring and versioning through Web servers that implement remote resource control.

Work here at UCI has included major input into the design and implementation of the protocol both here and at variouse software vendors. The most recent contribution has the the development and distribution of the first WebDAV client application DAVExplorer. Jim Whitehead has led the effort in creating the standard and he has provied valued input to Joe Feise and myself as we built DAVExplorer.

Recent Work

Redesigning and implementing DAVExplorer to comply with the latest version of the WebDAV standard. Specific items which were addressed during development include XML namespaces and access control. DAVExplorer has been released as open-source in order to allow all potentional WebDAV users to have a client application which they can study for future WebDAV applications.

WebDAV API -- A WebDAV API is being developed in order to facilitate the creation of WebDAV client applications.


libwww-ada95 is a library of Ada95 packages that will eventually provide a simple and consistent programming interface to the World Wide Web. This library is being developed as a collaborative effort to assist the further development of useful WWW clients and tools.

Other Influences in Computing

I am interested in the work by the following people. I hope to some day integrate ideas generated through their influence into my work.
