meta
Usage:
meta [<item> ...]
Provides information about the metadata for each column. This filter turns the table sideways, so that each row of the output corresponds to a column of the input. The columns of the output table contain metadata items such as column name, units, UCD etc corresponding to each column of the input table.
By default the output table contains columns for the following items:
Index
: Position of column in table
Name
: Column name
Class
: Data type of objects in column
Shape
: Shape of array values
ElSize
: Size of each element in column (mostly useful for strings)
Units
: Unit string
Description
: Description of data in the column
UCD
: Unified Content Descriptor
Utype
: Type in data model
However, the output may be customised by supplying
one or more <item>
headings.
These may be selected from the above as well as the following:
UCD_desc
: Textual description of UCD
Any table parameters of the input table are propagated to the output one.
