NCITS Announces the 2nd Public Comment Period for X3.285:199x,
Metamodel for the Management of Shareable Data

Washington D.C., November 1997 - NCITS (National Committee for Information Technology Standards) is announcing the 2nd public comment period for X3.285:199x. Development of this draft standard is being done in Technical Committee L8, Data Representation.

The public review extends from December 5, 1997 to February 3, 1998.

The goal of data registration is the maintenance of the meaning, representation, and identification of units of data over time and distance. Coherence and persistence of data descriptions and usage depend on accurate documentation. The process for documenting data descriptions is data registration and the place for documenting these descriptions is a data registry.

A data registry is a place to keep facts about characteristics of data that are necessary to clearly describe, inventory, analyze, and classify data. A data registry supports data sharing with cross-system and cross- organization descriptions of common data. Units of shareable data have precise identifiers, meanings, structures, and values. They are consistently deployed among users and systems and are centrally administered within an organization. Data registries may be organized into federations for interchange among many enterprises. A data registry assists users of shared data to have a common understanding of a unit of data's meaning, representation, and identification. Just as a data registry may assist users in understanding like units of data, registries also assist in the understanding of differences of similar but different units of data.

This standard specifies the structure of a data registry. The structure is stated in the form of a conceptualdata model.
