Abstract
The DIGMAP project researched automated methods for enriching metadata records with structured geo-temporal information. This paper presents our findings regarding the use of XML technology for expressing transformations between the different XML schemas used in DIGMAP metadata records and service interfaces. Both XSLT and XQuery are functional, declarative languages that effectively support XML data integration. They are also extensible, in the sense that new functions can be specified in Java and then combined with general XPath expressions. We extended an XSLT/Xquery engine with additional functions for processing spatio-temporal information and for dealing with incompleteness and inconsistencies in the data. The paper discusses the application over different XML formats and metadata standards.
