Information Systems Frontiers Journal paper
Finally! My Information Systems Frontiers Journal paper is published.

Title of the paper:
A theoretical investigation of the emerging standards for web services
Abstract:
Currently, standards for web services are being developed via three different initiatives (W3C, Semantic web services and ebXML). To the best of our knowledge, no theoretical perspectives underlie these standardization efforts. Without the benefit of a strong theoretical basis, the results, within and across these initiatives, have remained piecemeal. We suggest ‘Language–Action Theories’ as a plausible perspective that can effectively define, assess and refine web services standards. In this paper, we first investigate the existing initiatives to identify commonalities that point to theories of ‘Language–Action’ as an appropriate theoretical basis for web services standards. Next, we adapt work from these theories to develop a comprehensive reference framework for understanding web services standards. Finally, we use this reference framework to assess the three initiatives, and analyze the findings to provide insights for future development and refinement of web services standards.

Paper accepted at the ICSOC PhD Symposium
Paper Title:
A Study of Language-Action Perspective as a Theoretical Framework for Web Services
Abstract:
This dissertation contributes to services science discipline by examining appropriateness of Language-Action Perspective (LAP) as a theoretical framework for web services, the technology component of services science. This study is conducted through three essays. The first (completed) investigates whether LAP constructs can describe and explain the web services architecture. Findings from this essay indicate that there is lack of mechanisms to generate conversation policies that guide interactions between applications. Conversation polices are crucial for developing large-scaled enterprise integration solutions using web services. The second (work-in-progress) builds on this finding. This essay demonstrates appropriateness of LAP constructs to structure design knowledge to develop web services solutions for enterprise integration. The third (work-in-progress) evaluates usefulness of LAP structured design knowledge to develop web services solutions (artifact developed in the second essay).

CACM special issue on Services Science
Services Science discipline explores the underlying phenomenon beyond services economy. Services economy currently dominates global economy; nearly 2/3 of the global economy activity is from services sector. This shows how important services science discipline is. However, this discipline is taking its baby steps with lot much more to be explored and challenges to be faced.
CACM special issue on Services Science that appeared in July 2006, show cases shows importance of this discipline and challenges it faces.

CACM special issue on Language-Action Perspective (LAP)
My dissertation aim is to show that Language-Action Perspective (LAP) is appropriate theoretical framework for web services.
LAP has been around for two decades but it has not reached mainstream organization computing. It is not part of teaching curriculum in universities is mere evidence of it.
Web service provides an opportunity for this community to reach mainstream. I explore this possibility in my dissertation.
CACM Special issue on LAP which appeared in May 2006 show cases some of works of prominent LAP researchers.

MS Thesis Software helps to reduce 23% leadtime
As part of Master of Science with Major in Industrial Engineering (from Penn State University), I had developed a software tool to guide metal casting pattern designer to design better pattern in their first iteration.
It should be note that design pattern is more of art than science. Penn State was involved with larger project where huge amounts of data was gathered. Data analysis on these date produced certain analytical value that can be used for designing patterns.
I had used those analytical values and developed a designer-friendly software guide tool to design metal casting patterns. Trail run of this tool was conducted at McConway & Torley Group, Pittsburgh PA. Trail run of this software has improved casting feature dimensional conformance from 59% to 82% for large green sand castings.
Link for report regarding this (see page 22 in the report).

Paper Title
Designing Enterprise Solutions with Web Services and Integration Patterns
Abstract
Web services are an ideal implementation platform for integrating disparate legacy systems because they are platform-independent. Enterprise Integration Patterns (EIP) represent possible design solutions that may be used to construct these enterprise integration solutions. Constructing design solutions with EIP that build on the platform-independence allowed by web services requires that the former be converted into mechanisms that may be implemented with the latter. One such mechanism is conversation models that may be used to implement interactions among web services representing different legacy systems. No methodologies exist that designers can use to construct integration solutions using web services and EIP in this manner. In this paper, we outline such a methodology that generates the design elements in the form of conversation policies for web services.

Waterfall 2006 -- "Come on in, the water's fine."
Well it seems Waterfall system of developing software is making a come-back.
Some one is working too hard to bring it back into our life and make us laugh.

Bright Future for J2EE Web Services Development
This article appeared in Web Services Journal on October 23.
http://www.sys-con.com/story/?storyid=46718
J2EE based Web Services does have bright future due to broad range of J2EE applications which allows us to expose our existing applications as Web Services and some of those tools does work at a minimal complexity level. Glad that author pointed out importance of security, reliability, and performance of Web Services, without which there is no future for Web Services.

Application Server Architecture and BPEL - Promises and challenges
This article appeared in Web Services Journal, July 2, 2004. Author of the article - Amlan Debnath.
http://www.sys-con.com/story/?storyid=45517&DE=1
This article provides good overview of motives of BPEL and reason outs why BPEL is the core of web service. Author says that BPEL is designed with asynchronous services at its core, but this complicates the process of building a scalable, reliable BPEL engine. Author explains functionality of BPEL process using a simple order management process. Author figuratively explains evolution of application and server platform. Author provide overview of other key standards that are being developed, which are Extensible WSDL Binding Framework (JSR-208), Process Flow Coordination (BPEL), Reliable Web Messaging (WS-Reliability), Security (WS-Security), XML Data and Transformation (JAXB, XQuery), User Interactivity (WSRP), and Choreography and Contracts (WS-CDL). Even though author suggests that many standards are less mature, he believes these developments are going to dramatically change how we build applications and that the application server and BPEL are at the core of this new wave.
I also agree with author that even though many standards are still immature, web services is going to stay and success of web services depends upon success of BPEL. It is good to see industry recognizes this fact and actively working on to produce better tools.
