Mark Logic Named to KMWorld Magazine's "100 Companies That Matter in Knowledge Management" for Third Consecutive Year

Mark Logic® Corporation, provider of the industry's leading XML content server, today announced that it has been selected as one of KMWorld Magazine's "100 Companies That Matter in Knowledge Management" for 2007. This is the third consecutive year that Mark Logic has received this honor from KMWorld.

Since 2000, KMWorld's "100 Companies That Matter in Knowledge Management" has been recognizing companies that have helped create, enhance or define a market, and have a remarkable capacity for agile, customer-driven innovation. The list is compiled by colleagues, knowledge management practitioners, theorists, analysts, vendors and their customers.

"If there is a single trait shared by the companies that receive this award, it is their determination to treat their entire constituency chain, from top to bottom, with respect and without hubris," said Hugh McKellar, Executive Editor of KMWorld. "Clearly, attitude alone doesn't warrant inclusion on the list, attitude must be accompanied by elegance in the design and implementation of their software."

"We're honored to have been selected as one of KMWorld's 100 companies that matter for the third consecutive year," said Dave Kellogg, president and chief executive officer of Mark Logic Corporation. "We are confident that the consistent recognition we receive from the industry stems from our dedication to delivering solutions that effectively solve our customers' content challenges."
