The authors, PhD students at the Stanford University, present a prototype of the present widely popular search engine – Google. The authors described Google as a scalable search engine which aimed to provide high quality search results over a rapidly growing World Wide Web. Several technical details such as page rankings, anchor text, and proximity information have been explored. This is the classical paper that gave the world a new sense of searching the World Wide Web.

The authors, researchers at the Los Alamos National Laboratory, focus on the multifaceted use of the OAI-PMH in  a repository architecture designed to store digital assets at their research library, and to make the stored assets available in a uniform way to various downstream applications. The lightweight OAI-PMH protocol, which plays a prominent role, makes the propose approach attractive.

The dbXML Group, has developed dbXML as a Native XML Database. It is capable of string and indexing collections of XML documents in both native and mapped forms for highly efficient querying, transformation, and retrieval. In addition to these capabilities, the server may also be extended to provide business logic in the form of scripts, classes and triggers.

The authors, researchers at the Argonne National Laboratory & University of Chicago and University of Southern California, define the field of Grid computing. They shed light on the virtual organizations, and the specific issues associated with such a structure. They present a Grid architecture, which they claim is open and extensible. The need for defining standard protocols is rightly emphasized. Finally, they relate Grid concepts to many other popular contemporary technologies.

The author, senior scientist at the Argonne National Laboratory & University of Chicago, analyzes a very important question in this document. He provides a three-point checklist that according to him define exactly what a Grid is. He justifies that for a system to classify as a Grid, it should have coordinated resources that are not subject to centralized control, use standard, open, general-purpose protocols and interfaces and should deliver nontrivial qualities of service.

This document provides information to the community regarding the specification of the Open Grid Services Infrastructure (OGSI). Building on both Grid and Web services technologies, the Open Grid Services Infrastructure (OGSI) defines mechanisms for creating, managing, and exchanging information among entities called Grid services. They also provide a full specification of the behaviors and Web Service Definition Language (WSDL) interfaces that define a Grid service.

The Globus Toolkit is an open source software toolkit used for building grids. It is being developed by the Globus Alliance and many others all over the world. A growing number of projects and companies are using the Globus Toolkit to unlock the potential of grids for their cause.

This document is intended as a starting point for anyone who is going to program grid-based applications using the Globus Toolkit 3 (GT3). We also hope experienced GT3 programmers will find it useful to learn about the more advanced aspects of GT3 and Grid Services.

The goal of this Redpaper is to provide the critical jump-start for someone who wants to learn about GT3 but has little or no experience with prior Globus releases or grid computing in general. It show you how to implement a GT3 demo or a proof-of-concepts scenario. Also, it illustrates the high-level concepts of the toolkit components and the overall architecture.
