Abstract
The CORE project is an electronic library of primary journal articles in chemistry, containing about five years of twenty primary journals published by the American Chemical Society (about 425,000 pages). Unlike many digital library projects, CORE includes both a scanned image and a marked-up ASCII version (represented in Standard Generalized Markup Language, or SGML) for each page of the publisher's database. Each page was scanned and segmented, with graphical units isolated and linked to figure references in the articles. The original machine-readable typography was converted to SGML format and the results were used to build databases with indexes for full-text Boolean searching; a single search engine served data for each of three X-Window interfaces.

An XQuery engine for digital library systems
JCDL '03: Proceedings of the 3rd ACM/IEEE-CS joint conference on Digital librariesXML is now a standard markup language for web information. Many application areas are producing XML documents on the web. This situation urges digital library systems to deal with not only typical text documents but also XML documents. XML documents are ...
An XQuery Engine for Digital Library Systems that Support XML Data
SAINT-W '04: Proceedings of the 2004 Symposium on Applications and the Internet-Workshops (SAINT 2004 Workshops)XML has become widely accepted for both representation and exchange of data over the Internet. This situation urges digital library systems to deal with XML documents as well as typical text documents. A standard query language is very helpful for ...
