Semantic searching may be slightly in the future but redevelopment of ADS systems is already well underway. We are working from the bottom up; starting with hardware and software upgrades. Services are now distributed between a number of Sun® servers running under the Solaris operating system. This spreads the load and consequently makes access quicker. The catalogue is being migrated to a recently-installed enterprise level database system, Oracle® 8i. The opportunity is also being taken to restructure the data. Again this will quicken access and also facilitate the application of more complex queries to data held by the ADS. Further, a new enterprise level Web application server has been installed to manage the link between the database and the web server. Macromedia’s ColdFusion will truly facilitate the development of the ‘next generation’ Archarch.
