Dynamic Attributes
Overview
A Dynamic Attribute is a series attribute defined in a Data Structure Definition where the value for the attribute is derived at the time the dataset is generated. The derived value may include a mixture of hard coded text and reported values from any number of Dimensions for the series.
A typical use case is to provide a Series Title giving each series a human readable description of what data the series is describing. If the series title attribute is set to be a dynamic series attribute then the text for the series title can be derived from other dimensions such as reporting country, series indicator, frequency, and so on. Therefore, a derived title may look something like this:
Annual data of employment status in the United Kingdom
Where the terms Annual, employment status, and United Kingdom are taken from the Frequency, Indicator, and Country dimension respectively.
Supported Features
- Dynamic Attributes can be applied to Series, Observation, and Group level attributes
- Multilingual text is supported
- Variable placeholders enable the text to contain Code Ids, Labels, and Descriptions for any coded Dimension value
Making an Attribute Dynamic
To create a dynamic series attribute, add an Annotation to the Attribute with the Annotation Type of FR_DYNAMIC. The Annotation Text holds the text to output, and can be provided in each locale that requires support in the output.
Variable placeholders are supported using the syntax: $[COMPONENT_ID] for example $[FREQ], the id, name or description of the coded value can be used by adding the postfix .id, .name or .desc
Example
| Variable Example | Output Text Example |
|---|---|
| $[INDICATOR.id] | EMP |
| $[INDICATOR.name] | Employment |
| $[INDICATOR.desc] | Status in employment |
Example
Attribute = SERIES_TITLE
Annotation Type = FR_DYNAMIC
Annotation Text (en) = $[FREQ.name] data of $[INDICATOR.name] in the $[COUNTRY.name]
