2. Includes additions to
sub-clause 1.3 - Exclusions
Sub-clauses 1.1 and 1.2 outline the major topics
within the scope of this part of
ISO/IEC 11179.
Sub-clause 1.3 identifies aspects not currently addressed. Sub-clause 1.4 provides examples of
activities where this part of
ISO/IEC 11179 may be applied.The scope of this standard is outlined in
sub-clauses 1.1 and 1.2. Sub-clause 1.3 identifies
aspects currently excluded from this Standard. Sub-clause 1.4 provides examples of
activities where the standard may be applied
The primary purpose of this Part of this International Standard is to
specify the structure of a metadata registry.
A comprehensive metadata registry management function requires a set of
rules and procedures. These rules and procedures are set out in the following
Clauses and Annexes and are complemented elsewhere in this Standard as follows:
a)
the
definitions of metadata objects are in Clause 3.3 of this Part of the standard;
b)
the
structure of the registry in the form
of a conceptual data model is in Clause 4 of this Part of the standard;
Aspects of
the registry are expanded on in other parts of this standard, as follows:
a)
rules
and guidelines for classifying metadata are in Part 2;
b)
rules
and guidelines for the formulation of definitions are in Part 4;
c)
naming
and identifying principles for metadata are in Part 5;
d)
rules
and guidelines for registering metadata are in Part 6 of the International
Standard.
While the model
diagrams are presented in UML format, this standard does not assume nor endorse any
specific system environment, database management system, database design
paradigm, system development methodology, data definition language, command
language, system interface, user interface, computing platform, or any
technology required for implementation. The standard does not directly apply to
the actual use of data in communications and information processing systems.
This Part
of this International Standard also specifies basic attributes which are
required to describe metadata items, and which may be used in situations where
a complete metadata registry is not appropriate (e.g. in the specification of
other International Standards). These
basic attributes are described in clause 5.
This Part
of this international standard does not currently support the following
requirements.
a)
Complex
data structures, encapsulation, stereotyping and inheritance;
b)
Ability to enforce
uniqueness of names within a Context;
c)
Specification of Naming
Conventions for a Context;
d)
Prescribed conceptual domains and
value domains for the attributes in the metamodel;
e)
XML
documents;
f)
Application
Programming Interfaces (APIs) and associated bindings to access a registry.
It is anticipated
that some of these requirements will be addressed in future editions of this
Standard, or in companion standards or technical reports.
This Part of this International Standard applies to activities
including:
a)
the
definition, specification and contents of metadata registries, including
interchanging or referencing among various collections of data elements;
b)
the
design and specification of application-oriented data models, databases and
message types for data interchange;
c)
the
actual use of data in communications and information processing systems;
d)
interchange
or reference among various collections of metadata.
