Introduction

The Content Source Description (CSD) is a digital libarary service that supports the execution of content-based queries against a number of content sources (such as collections) that are associated with DILIGENT indices.

Implementation Overview

Among the many possible ways of implementing a content source description service, the provided reference CSD service is based on the representation of text sources as term histograms. A histogram basically contains the most representative words and phrases of a content source (i.e. a content collection) together with statistics information. To obtain these statistics, the reference CSD service interacts with index services in order to derive statistical information from full-text DILIGENT indices of internal sources and to subscribe for notifications should these indices change (notifications will be available in the beta-release of the project).

  • DiligentProvider
  • KXML (version 2.3.0)
  • Contentmanagement
