Integrated Information

big upcoming feature is Topics. These are basically canned queries, similar to "custom views" in some email packages or saved searches from a search tool. In addition to storing Favorites, which are just static links within a site, a member could have a customized topic that might be "Show all NewsItems about the CMF that were posted in the last two weeks". This gets turned into an optimized Catalog query that is always live. This is a powerful personalization feature, and proves even more useful in some other Portal types described below.

Integrating heterogeneous databases

Combining Topic Maps and Holonomic Object technology Nan Kevin Gelhard, Summit Racing Equipment, & Paul Prueitt, OntologyStream Heterogeneous databases can be integrated using topic maps as the controlling interface and a Holonomic Object as generalized database. These two technologies are used together to connect a current commercial data and procedural environment to a prototype B2B/B2C portal. The topic map is used as an "observational data warehouse" for legacy databases, while Holonomic Object Technology provides fast, reliable transformations between legacy databases and topic maps. Within highly ramified buyer/seller events, the portal answers such questions as "What fits my need? Is it in stock? If not, when is it expected? What is the selling price?"
