The first phase
18
ISO 11179 Metadata Standard

• Application of the Standard
• International standard for interoperability of
  metadata.
• Application of the standard provides a common
  structure for managing Business Definitions.
• All major aspects of ISO 11179 have been
  implemented in the Business Definitions Registry.
• Business definitions are compliant with ISO 11179
  and include extensions.

19
ISO 11179 Metadata Standard
Implementation Benefits

• Agreed meanings
• Unambiguous
• Interoperability
• Future proof definitions
• Shared capabilities

20
ISO 11179 Metadata Standard
Implementation Issues

• Standard is still maturing
• Subject to interpretation
• Many partial implementations
• Logical inconsistencies
• No Registry Implementation Model

21
ISO 11179 Metadata Standard
Implementation Basics

• Consider and interpret all aspects of the
  Standard
• Produce a Standard Core document describing
• Understandings of the Standard
• Constraints to the Standard
• Variations to the Standard
• Not implemented aspects of the Standard
• Identify the scope to be implemented
• Produce a requirements document for each aspect.

22
ISO 11179 Metadata Standard
Understanding - Example
The Standard requires an Administered Item to be
defined within a Context. A Context is a type of
Administered Item.

• Understandings
• Every Administered Item must be defined within a
  Context.
• Every Context is an Administered Item.

23
ISO 11179 Metadata Standard
Constraint - Example
The Standard permits an Administered Item to have
one or more Definitions, one or more Names in one
or more Contexts. Potentially ambiguous and
confusing

• Constraint Applied
• One Definition with one Name in one Context.
• This constraint achieves clarity and complies
  with the Standard

24
ISO 11179 Metadata Standard
Variation - Example
The Standard provides an Effective From and
Effective Until period for each Administered
Item. This is not adequate for many business
situations.

• Variation Applied
• An additional Applicable From and Applicable
  Until period to deal with retrospective
  application.
• This variation provides chronological accuracy
  and resolves logical inconsistencies.

25
ISO 11179 Metadata Standard
Not Implemented - Example
The Standard permits a Preferred Definition,a
Preferred Name, and a Preferred
Standard. Preferred to what? Implies some
grouping

• Preferred not implemented
• This is not implemented to avoid ambiguity and
  complies with the Standard

26
ISO 11179 Metadata Standard
Other Extensions to the Standard
Inter Registry protocols Facilitates transfer,
merge and split of content. Lineage
links Facilitate continuity and superseded
aspects. Context classification Automatic
classification based on Context.

What would improve implementation

• A Registry Implementation Model (RIM)
• Provide a clear interpretation
• Provide a clear set of rules
• Provide a defined data structure
• Provide a defined process structure

29
ISO 11179 Metadata Standard

• How a RIM will enhance the Standard
• Speed maturity of the Standard
• Provide certainty among implementers
• Enhance adoption of the Standard
• Resolve issues by example

• How a RIM could be developed
• Collective assembly of a RIM by current
  implementers
• Agreement on interpretation and implementation
• Shared techniques and resources
