Promenade is a joint project of the School of Library and Information Science of the University of Pittsburg, and the National Agricultural Library of the US Department of Agriculture. The system provides access to high-quality images over the Internet, with search capabilities on field contents and free-text matching, browsing capability and high object-oriented query and retrieval of an image database over a wide area network. The image database contains two collections, a set of botanical prints from Curtis Botanical Magazine (1787-1807) and a collection of photographs for plant pest identification provided by Dr Randy Heatly of Michigan State University. For the Curtis collection, images of text and flora from the first 26 volumes of the magazine, plus structured data fields, are included. The pest collection consists of images of insects, molds and plant diseases with a text description plus structured data fields. Both collections include thrumbnail representations plus primary images and total over 4000 images stored within 1500 documents. Promenade is implemented in the Ontos Object-oriented Database Management System with class libraries written in C++. The use of Ontos query language, OSQL, has made it possible to modularize the development of the network, user interface and database elements of the overall system. An early version of the system provided a user interface developed in Visual Basic, with connections between the remote clients and the server established and maintained through a dialogue implementated as a protocol of ftp calls. Subsequently the database was made available on the Internet through Mosaic, greatly enhancing the availability and functionality. Promenade was designed as a test bed to study aspects of neworked access to image databases over the Internet, using a variety of user groups (researches, agricultural agents, laypersons). Factors being examined include the modalities of use of an image collection when multiple resolutions and formats are avalaible, the impact of compression/decompression procedures on image use, and systems issues such as image quality, transmission and display time.
