Introduction

The FEA Data Reference Model (DRM) is intended to promote the common identification, use, and appropriate sharing of data/information across the federal government through its standardization of data in the following 3 areas:

Data Description: A standard approach to describing an agency’s structured, semi-structured, and unstructured data. Structured data includes individual entities (such as those defined within a data architecture), their attributes, and the relationships between them. Unstructured data includes multimedia files, and documents created using earlier versions of applications such as Microsoft Word. Semi-structured data includes Web pages and e-mails.

Data Sharing: A standard approach to describing the characteristics and requirements of interagency data exchanges, including data sources. Defines a standard message structure known as an Information Exchange Package.

Data Context: A standard approach to representing taxonomies that an agency uses to categorize its data. Such categorization enables the business context of data to be well understood.

In order to facilitate implementation of the DRM by federal agencies, OMB will provide agencies with a DRM Schema (also known as a “DRM XML Profile”). The DRM Schema will enable federal agencies to submit XML instances to OMB that contain information for the agency pertaining to the 3 DRM areas described above. The DRM Schema will also facilitate data modeling efforts within agencies by providing a capability by which – for example – physical data models may be derived from logical data models. Instances of the DRM Schema may also potentially be used for configuration and operational purposes , e.g. to automatically configure and/or categorize a data source, to support service-oriented architecture (SOA) based exchanges between agencies, etc.

drm:ExternalExchangePackageRef

(Comments?)

Specifications
Definition: Points to data sharing service interfaces created using an approved standard. For a standard to be approved, it must be:

1. An open, widely implemented standard, available free-of-charge and unencumbered by royalty or patent claims, or a standard implemented by a government agency
2. A well-documented, durable standard (i.e., under version/change control, well-documented, backward compatibility, etc.)
3. Provides semantics for modeling, at a minimum, service inputs and outputs/payloads, service protocol, and service endpoints.
4. Provides semantics for assigning an identifier per element that is guaranteed unique within the particular model.

Candidate standards for implementing data exchange services include WSDL.

drm:NodeRef

(Comments?)

Specifications
Definition: A link to a taxonomy node. The unique ID of the target taxonomy node is documented in the rdf:idref attribute. The type attribute specifies the nature of the relationship, e.g. "partOf", "instanceOf", or "subclassOf". This element can be used by the following elements to link to a taxonomy node:

1. Entity
2. Resource
3. DataSource
4. ExchangePackage
5. Another taxonomy node
6. External references to any of the above.
7. Attribute: When used with an attribute, a NodeRef typically points to a taxonomy node containing a Terms collection providing a "controlled vocabulary" to constrain values populating instances of the attribute.

For web pages that need to point to a DRM taxonomy node in an inline fashion, standard HTML META tags can be used. For example:

<meta name="drm:NodeRef" content="http://cosine.cim3.net/file/work/DRM/data_dictionary/examples/DRM_Instance_Example_OJP_IT.xml#182 />
