Annotation
Describes the representation of the variable in the data set. Describes the function of the variable, variables or standard weights that may be used to weight this variable during analysis, imputation and processing information, other variables used to create the value of this variable through concatenation, valid value representations (valid for analysis of respondents), missing value representations, aggregation methods used to generate the content of the variable, and additivity information.

Attribute Detail (all declarations; defined within this component only; 1/1)
additivity-
Records type of additivity, such as 'stock', 'flow', 'non-additive'.
Attribute Value
enumeration of xs:NMTOKEN |
Enumeration: |
"Stock" |
- |
A count of objects at one specific time. In general items in a non-hierarchical table of Stock figures can be added together to determine the total. |
"Flow" |
- |
A measure that is taken over time and should be treated as the number of items per a unit of time. Analogous to a rate or a speed. |
"NonAdditive" |
- |
Due to the nature of the content or the measure, these data cannot be aggregated to determine a sum or accounting of activity. |

Content Element Detail (all declarations; defined within this component only; 10/10) -
Provides a reference to other variables and describes the method for deriving the value of this variable by concatenating a collection of other variables. This is useful in creating concatenated keys.
XML Source (w/o annotations (1); see within schema source)
-
Reference to the imputation process described as a General Instruction in a ProcessingInstructionScheme.
XML Source (w/o annotations (1); see within schema source)
-
Records the measurement unit, for example, 'km', 'miles', etc. Supports the use of a controlled vocabulary.

-
Reference to a delineation of the values defined as "missing" for this variable.
XML Source (w/o annotations (1); see within schema source)
-
Indicates the type of aggregation method used. Supports the use of a controlled vocabulary.
Simple Content
XML Source (w/o annotations (1); see within schema source)
-
A reference to either a general or generation instruction that was provided to those who converted information from one form to another to create a particular variable. This might include the reordering of numeric information into another form or the conversion of textual information into numeric information.

Subst.Gr: |

Describes the actual representation of the variables' values. Delineate the values defined as missing in a separate MissingValuesDelineation and reference from MissingValuesReference.
XML Source (w/o annotations (1); see within schema source)
-
Reference to one or more weight variables that may be used in analyzing this variable.
XML Source (w/o annotations (1); see within schema source)
-
Reference to the StandardWeight found in the Weighting description, which is relevant for analyzing this variable. A standard weight is a single weight used for all variables of a specific type or for a specified sub-universe.
XML Source (w/o annotations (1); see within schema source)
-
Describes a specific function of the variable, such as identity, weight, geographic variable, time, date, currency, etc. This is a more extensive means of identifying the function of the variable than the Boolean indicators on the variable. Allows for agency specific designations. Supports the use of a controlled vocabulary.
