•

XML and Data Warehouse (DW) applications.

•

eXtensible Business Reporting Language (XBRL), based on XML.

•

XBRL represents business information, and it is multidimensional.

•

The target is a "Data Warehouse".

•

The objective is to analyze the semantics of taxonomies and instances,

Conclusions

and then map this data model to the Multidimensional Data Model (Conceptual Model).
