7. Element and Encoding Scheme Attributes Legends

Element attribute tables are modelled after two guidelines documents:

  • Treasury Board of Canada, Secretariat, Guidelines for Metadata Application Profiles in the Government of Canada, Version 2.3, January 20, 2005; and,

  • European Committee for Standardization, Dublin Core Application Profile Guidelines, CWA 14855, November 2003.

In addition, the GC RMAP element attribute tables include the mandatory attributes outlined in ISO 11179, namely, Name, Definition, Value Domain, and Datatype Name.

Each metadata element is described in Section 8 according to the following:

Attribute Attribute Description

Identifying Attributes

Name

A unique token assigned to the element. Use this if there is no URI for the element. The character strings representing element names are immutable. This attribute is the same as the Name attribute within the GC RMMS.

Label

A human-readable label assigned to the element. A suggested designator for the use of this element on a graphical user interface. This is the preferred label.

Defined by

An identifier of a namespace, a pointer to a schema, or a reference for a document within which the element is defined. Use this, in combination with the name and/or label to identify an element if there is no URI.

Element URI

A Uniform Resource Identifier (URI) used to uniquely identify the element.

Definitional Attributes

Definition

A statement that represents the concept and essential nature of the element. Note: This attribute appears only in the tables of those elements declared as Government of Canada elements. This attribute is the same as the Definition attribute within Section 7 of the GC RMMS.

DC Definition

The definition of the Dublin Core element as specified by the Dublin Core Metadata Initiative. Note: This attribute appears only in the tables of those elements adopted from the Dublin Core. This attribute is the same as the Definition attribute within Section 6 of the GC RMMS.

DC Comment

Comment about the Dublin Core element as specified by the Dublin Core Metadata Initiative. Note: This attribute appears only in the tables of those elements adopted from the Dublin Core.

Purpose

Indicates what will be achieved by using the element.

Rationale

Reasons for inclusion of the element including the citation of any authorities. In most cases, relevant excerpts only of the text are provided. Since in many cases, disparate points are addressed within the text of the ISO sections quoted, ellipses are used to omit non-relevant text. They are not used to omit crucial material which may be applicable to the rationale for the element.

Value Domain

A set of permissible values. Permissible values may either be enumerated (i.e. from a controlled vocabulary) or expressed via a free-text description. This attribute is the same as the Value Domain attribute within the GC RMMS.

Datatype Name

A designation for a datatype. A datatype is a set of distinct values, characterized by properties of those values and by operations on those values. Indicates the type of data that can be represented in the value of the element at the record and/or file level. This attribute is the same as the Datatype Name attribute within the GC RMMS.

Constraint

Constraints that narrow the applicability of the element within this application.

Obligation

Indicates whether the element is mandatory, mandatory if applicable, or optional. Obligation establishes GC wide standards yet accommodates institution-specific business rules where applicable. Details of the obligation are provided in the element's comments and guidance.

Relational Attributes

Encoding Scheme

The described element is qualified by the referenced encoding scheme(s). An encoding scheme may either control the format or convention used to record the value or control the list of allowable terms (i.e. a controlled vocabulary) for the value. Lists the encoding scheme(s) allowed.

References

A list of pertinent references for further information about the element or its application.

Linkages

Specifies the names of other elements for which dependencies and relationships between or among elements exist. Details of the linkage are provided in the element's comments and guidance.

Conditions of Application - Record

Format

Indicates the required format of the values, if any, at the record level. "Free text" indicates that the value may be input using natural language (i.e. there is no constraint) while "Text" indicates the value comes from a controlled vocabulary specified in the Encoding Scheme attribute.

Modifiable Pre Record Declared Locked Post Record Declared Locked

Indicates if the value of the element can be altered before the record is declared locked. Indicates if the value of the element can be altered after the record is declared locked.

Occurrence

Indicates any limit to the repeatability of the element at the record level.

Conditions of Application - File

Format

Indicates the required format of the values, if any, at the file level. "Free text" indicates that the value may be input using natural language (i.e. there is no constraint) while "Text" indicates the value comes from a controlled vocabulary specified in the Encoding Scheme attribute.

Modifiable

Indicates if the value of the element can be altered at the file level.

Occurrence

Indicates any limit to the repeatability of the element at the file level.

Encoding scheme attribute tables are modelled after the following guidelines document:

Each encoding scheme is described in Section 9 according to the following:

Attribute Attribute Description

Identifying Attributes

Name

A unique token assigned to the encoding scheme. Use this if there is no URI for the encoding scheme.

Label

A human-readable label assigned to the encoding scheme.

Defined by

An identifier of a namespace, a pointer to a schema, or a reference for a document within which the encoding scheme is defined. Use this, in combination with the name and/or label to identify a encoding scheme if there is no URI.

Encoding Scheme URI

A Uniform Resource Identifier (URI) used to identify the encoding scheme.

Definitional Attributes

Description

A statement that indicates the nature and purpose of the encoding scheme as understood by the Records Management Sub-Group - Application Profile.

Comment

Additional information about the encoding scheme and its application.

Relational Attributes

References

A list of pertinent references for further information about the encoding scheme or its application.

Refines

The described encoding scheme semantically refines the referenced term.

Conditions of Application

Constraint

Constraints that narrow the applicability of the encoding scheme within this application.

Datatype Name

A designation for a datatype. A datatype is a set of distinct values, characterized by properties of those values and by operations on those values. Indicates the type of data that can be represented in the value of the term at the record and/or file level.

Format

Indicates the required format of the values, if any.
