ISO/IEC 11179, Parts 1 - 6
Part 1: FrameworkPart 2: Classification for Administered ItemsPart 3: Registry Metamodel and Basic Attributes Part 4: Formulation of Data DefinitionsPart 5: Naming and Identification PrinciplesPart 6: Registration
4
Part 1: Framework
Facilitates acquisition and registration of data Expedites access to and use of data Simplifies data manipulation based on
characteristics described by metadata Enables development of a data representation
metamodel for CASE tools and repositories Facilitates electronic data interchange and data
sharing Includes definition of terms
5
Part 2: Classification for Administered Items
Deriving and formulating abstract and application administered items
Ensuring appropriate attribute and attribute-value inheritance
Reducing ambiguous information Recognizing relationships among data
element concepts, data elements and other administered items
6
Part 3: Registry Metamodel and Basic Attributes
Specifies a metamodel and attributes to describe data items (e.g., name, definition, permissible values, size, representation, datatype)
Outlines other attributes that will provide information for data management
Provides for consistency in recording metadata information
Encourages comparison of data across systems Facilitates information exchange
7
Part 4: Formulation of Data Definitions
Define the meaning of data items Ensure consistency and quality Facilitate data shareability Contains both rules and guidelines
8
Part 5: Naming and Identification Principles
Defines the identifying attributes Describes the relationship of the attributes to
each other Includes principles by which naming
conventions can be developed and documented Describes an example naming convention
9
Part 6: Registration
Describes the procedure by which data items are registered and assigned an internationally unique identifier
Outlines steps in the assignment of Registration Statuses
Reviews the role of a Registration Authority
