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 three 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 three 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.

What's New in this Version:
- Integrated the Intelligence Community Information Security Marking (IC ISM) XML Schema Version 2.0. These attributes are being used to provide ISM information to the DataReferenceModel, ExchangePackage, and QueryPoint elements. This attribute group supercedes drm:Classification, which has been deleted.
- Added Temporal Coverage elements from the DDMS version 1.2 to the Resource, ExchangePackage, and DataAsset elements.
- Added the Terms collection as a child of Attribute. This will allow codelists to be directly attached to attributes in structured data entities.
- Added the following values to the type attribute's enumeration: equivalentTo and relatedTo. Reason: provides additional commonly used semantics for describing relationships between taxonomy nodes.
- Added PayloadRef as a child of ExchangePackage. Also added PayloadTransport. Reason: the intent of ExchangePackage is to provide high-level metadata about a repeatable exchange, as opposed to the low level technical details about the specific message. Therefore, the exchange package must provide a pointer to the artifact that does provide those details. PayloadRef contains an href attribute that includes the URI pointing to the message payload.
- Renamed AccessPoint to QueryPoint. This is a more descriptive name. Also renamed DataAccessPoints to QueryPoints.
- Added Geospatial Coverage elements from the DDMS version 1.2 to the Resource, ExchangePackage, and DataAsset elements.
- Renamed DataSource to DataAsset. Several elements were impacted by this change (e.g., DataSources, DataSourceRef, etc.).
- Changed rdf:id to rdf:ID and rdf:idref to rdf:resource to remain consistent with this document.
- Added additional enumeration values to the following elements and attributes: datatype, unit, keyType, and Language.

Definition: | This element points back to a related resource. It is used primarily to elaborate on a relationship between an Entity (or ExternalEntityRef) and a resource that aggregates instances of that entity. For example, a spreadsheet (Resource) that lists employee (Entity) information. It can also be used to link together two resources. It contains two attributes: type and rdf:idref. Type is generally "partOf". rdf:idref points back to the Resource's unique identifier. |

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, backward compatibility, etc.) 3. Provides semantics for modeling, at a minimum, entities, attributes, types, and relationships. 4. Provides semantics for assigning an identifier per element that is guaranteed unique within the particular schema. |

Definition: | Encapsulates a single "page view" of unstructured or semi-structured data, referenceable via a URI. This element aggregates numerous sub-elements, mostly metadata tags reused from the Dublin Core 1.1 set.
In some cases, Dublin Core metadata will be embedded in the actual resource itself. In this case, there is no need to repeat the metadata in the DRM instance. The Resource element can point to the actual resource itself, populating the rdf:id attribute with the resource's URI. |

Definition: | (GMI:BE_NUMBER, 1.0) Uniquely identifies the installation of the facility. The BE_NUMBER is generated based on the value input for the COORD to determine the appropriate World Area Code (WAC), the system assigned record originator and a one-up-number. Pos. 1-4, World Area Code (WAC). Pos. 5, A hyphen, '-', or an 'E', in the fifth position indicates that position-6 will contain values 0-9. Alternately, the fifth position may contain the first of a two-character system assigned record originator code, position-6 will then contain the second character of the system assigned record originator code. Pos. 6, May contain the second character of the system assigned record originator code, the one-up-number series will then begin in position seven, and range from 0001-9909. If the one-up-number series begins in postion 6, this position will contain the first of a five-position one-up-number, i.e., 00001-99999.Pos. 7-10, A one-up-number series. Depending on the content of position 5, the series may have begun in position 6 and have a range of 00001-99999. Or, have begun in position 7 and have a range from 0001-9999. |

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. |

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 /> |
