Abstract: The present invention relates to business intelligence systems. An enterprise's business intelligence may be embodied in business intelligence artefacts such as reports, queries, analytical documents, spreadsheets, etc. Over time, many of these documents are produced. The same artefacts may be produced by different departments in an enterprise. This is an inefficient use of resources. Further, when a user is producing an artefact, they add their own knowledge to the artefact (in the form of table names, column names, etc, that they have selected themselves using their business knowledge). This knowledge is not accessible.
