get_relationship_WasImportedFrom

This relationship specifies the import source for identifiers. It is used when reloading identifiers to provide for rapid deletion of the previous load's results.

Example:

get_relationship_WasImportedFrom -a < ids > table.with.fields.added

would read in a file of ids and add a column for each field in the relationship.

The standard input should be a tab-separated table (i.e., each line is a tab-separated set of fields). Normally, the last field in each line would contain the id. If some other column contains the id, use

-c N

where N is the column (from 1) that contains the id.

This is a pipe command. The input is taken from the standard input, and the output is to the standard output.
