Data Reference Model Version 1.0†
- 参照モデル(Reference Model)
- OMB - Office of E-Gov & IT - FEAPMO
Two of the major goals of the Federal Enterprise Architecture (FEA) are information sharing and the improved effectiveness of federal IT investments. Achieving these goals requires the ability to identify and use common data across the federal government. The Office of Management and Budget (OMB) has developed the Data Reference Model (DRM) to assist in the identification and use of common data. The DRM’s primary purpose is to promote the common identification, use, and appropriate sharing of data/information across the federal government.
To achieve this purpose, the DRM describes three basic standardization areas:
- Categorization of data
- Exchange of data
- Structure of data
Information sharing can be enabled through the common categorization and structure of data. By understanding the business context of data, DRM users will be able to communicate more accurately about the content and purpose of the data they require. This improved communication on the content and purpose of data will improve the ability to share information throughout the federal government. Exhibit A illustrates the basic areas of the DRM.
Categorization of Data: †
The DRM establishes an approach to the categorization of data through the use of a concept called Business Context. The business context represents the general business purpose of the data. The business context uses the FEA Business Reference Model (BRM) as its categorization taxonomy.
Exchange of Data: †
The exchange of data is enabled by the DRM’s standard message structure, called the Information Exchange Package. The information exchange package represents an actual set of data that is requested or produced from one unit of work to another. The information exchange package makes use of the DRM’s ability to both categorize and structure data.
Structure of Data: †
To provide a logical approach to the structure of data, the DRM uses a concept called the Data Element. The data element represents information about a particular thing, and can be presented in many formats. The data element is aligned with the business context, so that users of an agency’s data understand the data’s purpose and context. The data element is adapted from the ISO/IEC 11179 standard.
