A Generic Metadata Query Tool.
Verhoeven, B.; Duval, E.; Olivie, H.
This paper discusses a generic query tool that enables an end user to query a metadata store through filters that impose search criteria on attributes. The Metadata Query Tool (MQT) is generic in the sense that it dynamically creates its user interface, based on configuration files that define the metadata scheme and the query functionalities. Although, in principle, the tool can be used to query any relational database, it has been specifically developed to query educational metadata stored in the ARIADNE Knowledge Pool System. The first section of the paper is an introduction, followed by a section that describes the approach to filter-based queries. The third section explains the configurable aspect of MQT, both with respect to the metadata scheme, as well as with respect to the graphical user interface. Some details on the queries generated by MQT are presented in the fourth section. The fifth section covers some user interface aspects. The sixth section gives an overview of related research and tools. The current status is presented in the seventh section. (Contains 11 references.) (MES)
