Oracle has bought the intellectual property of Tacit Software and hired all of its software engineers. The terms of the deal were not disclosed.
Tacit is the company behind illumio, a SaaS collaboration and "expertise location" platform, and ActiveNet, an on-premises product with a similar purpose.
The system doesn't require users to maintain profiles; instead, a plug-in that is installed locally tracks their activity and builds a "dynamic, highly accurate profile of their expertise," according to the illumio website.
Oracle has bought the Tacit IP in order to boost its Beehive collaboration product, launched at its recent OpenWorld conference. Beehive combines features such as conferencing, email, calendaring, instant messaging and workspaces.
