What does Information Server help them achieve?

6

IBM Software Group

What don’t we do with metadata?

Information Server is not providing a general-purpose enterprise metadata repository

There is no intent to maintain third-party metadata

The metadata goal for Information Server is to provide linkages to what is known within the domain of “data integration.”
