摘要

Most information management scenarios today rarely have a situation in which all the data that needs to be managed can fit nicely into a single management system, such as a relational database or a knowledge base. Instead, we need to manage a set of loosely connected data sources, and typically face the following recurring challenges: 1. Users want be able to search the entire collection without having knowledge of individual sources. In some cases, they merely want to know where the information exists as a starting point to further exploration. 2. An organization may want to enforce certain rules, integrity constraints, or conventions (e.g., on naming entities) across the entire collection, or track flow and lineage between systems. Furthermore, the organization needs to create a coherent external view of the data. 3. The administrators may want to impose a single "support system" in terms of recovery, availability, and redundancy, as well as uniform security and access controls. 4. Users and administrators need to manage the evolution of the data, both in terms of content and schemas, in particular as new data sources get added (e.g., as a result of mergers or new partnerships). 5. The organization would like to globally capture human interactions with the sources (e.g., querying, excerpting, annotating, co-use) to provide value-added information about semantics, linkages and quality.
