6.1.18 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.
