<value xml:lang="en">
A date with yearly granularity.
The year concept is usually used directly in a slice definition to define a dimension that
contains year. For example, a slice for yearly population by country would be defined
as follows:
<![CDATA[<slices>
<slice id="country_slice">
<dimension concept="country"/>
<dimension concept="time:year"/>
<metric concept="population"/>
<table ref="country_slice_table"/>
</slice>
</slices>]]>
The table definition for this slice would be defined as follows:
<![CDATA[<tables>
...
<table id="country_slice_table">
<column id="country" type="text"/>
<column id="year" type="date" format="yyyy"/>
<column id="population" type="integer"/>
<data>
<file format="csv" encoding="utf-8">country_slice.csv</file>
</data>
</table>
...
</tables>]]>
And the data contained in the CSV file for this table would look like:
country, year, population
AF, 1960, 9616353
AF, 1961, 9799379
AF, 1962, 9989846
AF, 1963, 10188299
...
