Harmonizing the ISO 11179-3 and CWM Metadata Standards

Two influential metadata standards are ISO 11179-3 and the Common Warehouse Metamodel (CWM). The 11179-3 standard is used to facilitate system data integration and the CWM standard models artifacts needed for data warehousing applications which includes data movement among systems. They therefore have great overlap in their problem spaces and in their concrete modeled items, however their approaches are substantially different. Harmonizing the two metamodel standards is critical as information in repositories based on both standards are combined. The harmonization approach also leads to a more flexible application of the ISO 11179-3 standard to data problems.

We will cover:

• Design and use of the core ISO 11179-3 standard metamodel
• Basics of the design and use of parts of CWM
• Common areas of the two standards
• How they are harmonized
• Applications of the combination
