Microsoft’s Master Data Management tool, previously codenamed ‘Bulldog’ and slated to be included in the Office 14 release is now set to be included with Kilimanjaro – which seems to now be officially called SQL Server 2008 R2.
More details can be found at the SQL 2008 Official site. The rumour mill seems to imply that SQL 2008 R2 will drop at roughy the same time as Windows 7.
Just in case you have no idea what Master Data Management entails, it covers managing and centralising metadata within an organisation that may span many systems. The most common example is central management of customer records. For more insight and a more detailed explanation, I suggest you read this white paper on the subject by Roger Wolter and Kirk Haselden.
