Extract Table Spec

Node extracting the meta information from the input table (column names, types, etc.) The meta information is referred to as the table data specification and contains information such as column names, types, domain values (list of possible values for categorical columns) and lower and upper bounds. It also contains the information which of the columns have a view handler associated (optional operation). Each column in the input table is represented as a row in the output. This node can be used in conjunction with the Insert Column Header node, where the column names are extracted from the input table, then modified in the workflow and later merged back into the main table.

Options

Extract property handlers

If checked the information which of the columns have property handlers e.g. color handler associated is extracted, otherwise not.

Possible values as collection

If checked, the possible values of each columns are extracted as possible values, otherwise not.

Format of Type Names

Determines how the types of columns are represented in the output table. The following options are available:

• Identifier: The type names are represented with a unique identifier. This is the recommended option.
• Legacy Display Name: The type names are represented by their old display name. This option is intended to be used purely for backwards-compatibility for workflows created in version 5.4 or before.
• Display Name: The type names are represented by their display name. This name may change at any point with an update, so it is highly discouraged to match against this output in any way.
