Discovery Server is a search engine for the enterprise that sorts documents, files and even users by user-created taxonomies. Documents and users are rated by their expertise or usefulness, based on past use.
Lotus previously bundled the knowledge management tool with its K-station portal, which will now be sold as part of IBM's Websphere package.
The K-station technology will be integrated directly into Websphere sometime in spring 2002, said Krista Hiltz Kahn, Lotus's marketing manager for knowledge management products.
The IBM subsidiary said by offering the Discovery Server as a separate product, it could sell the server at a lower price and provide companies with greater flexibility in developing their knowledge management products.
The standalone version of Discovery Server costs $199 (£137) per user, per year. This covers both subscription and support, Kahn said. The software is available for download from 31 October.
Dave Newbold, development manager for Discovery Server, said a new feature of Version 1.1 was its ability to integrate Discovery Server functions into applications with a Java application-programming interface.
"Developers can extend their applications by incorporating Discovery Server technology into an existing e-business application to enhance functionality and increase their return on investments," said a statement from Lotus.
