Transforming the content management process at IBM.com

This case study explores the evolution of the Franklin Content Management System, developed by IBMs Internet Technology Group. Franklin began as a technology-driven process to provide a web content management solution with the following goals: content reusability, simplified management of content and design that enforces integrity and consistency, the customization of content to individual users, and the delivery of content to a variety of display devices.These goals were met in part by the decomposition of information into reusable fragments represented in XML. This approach provides unique opportunities in a content management system. However, it also raises some interesting challenges in the deployment of such a tool and the education of its users.The development of Franklin evolved over a two year period and has culminated in the deployment of 62 country portals within the ibm.com domain. Furthermore, concepts from the Franklin project are influencing the strategy and design of IBM offerings.

Design and implementation of an enterprise grid

This paper presents the design and implementation of intraGrid, an experimental grid based on the Globus ToolkitTM and deployed on the IBM intranet. The architecture and the main components of intraGrid are described. Then, the major technical challenges and their solutions are reviewed, including software packaging and distribution, the interface for administrative tasks, and the design and implementation of the three major services: information services, management services, and job submission services. The paper also describes the extensions and modifications to intraGrid that were required to create the ISD grid, a grid that is used for joint projects with customers and thus requires access by external users. The paper reviews the use of intraGrid by various teams of IBM researchers to date and outlines the plans for future applications. The work in progress to migrate the intraGrid to an OGSA-based (Open Grid Services Architecture-based) grid is also described.

XML data mediator integrated solution for xml roundtrip from xml to relational

This paper presents a system for efficient data transformations between XML and relational databases, called XML Data Mediator (XDM). XDM enables the transformation by externalizing the specification of the mapping in a script and using an efficient run-time engine that automates the conversion task. The runtime engine is independent from the mapping script. A parser converts a mapping script into an internal conversion object. For the mapping from relational to XML, we use a tagging tree as a conversion object inside the runtime engine, and use an SQL outer-join scheme to combine multiple SQL queries in order to reduce the number of backend relational database accesses. For the mapping from XML to relational, the conversion object is a shredding tree, and we use an innovative algorithm to process the XML as a stream in order to achieve linear complexity with respect to the size of the XML document.

Design of a Grid Computing Infrastructure Based on Mainframes.

Businesses are entering the next phase of e-Business, in which they need to be able to sense and respond to fluctuating market conditions in real time. IBM is leading the way toward this on-demand world and a number of initiatives are underway to investigate, design and deploy Grid technologies, which form one of the pillars upon which the on-demand environment can be built. Integral part of these efforts is the integration of existing mainframe resources in various data centers within a Grid environment. In this paper, we present a design that enables the sharing of underutilized capabilities of mainframes in a dynamic way. This approach promises to increase corporate efficiency, by improving return of investment (ROI) on data center investments and opens up the use of data center resources to new applications. An early prototype of the design has already been implemented, and a number of business and engineering applications are being tested on the prototype.
