fids_to_annotations

This routine takes as input a list of fids. It retrieves the existing annotations for each fid, including the text of the annotation, who made the annotation and when (as seconds from the epoch).

Example:

    fids_to_annotations [arguments] < input > output

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 identifer. If another column contains the identifier use

    -c N

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

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

Documentation for underlying call

This script is a wrapper for the CDMI-API call fids_to_annotations. It is documented as follows:

  $return = $obj->fids_to_annotations($fids)

Parameter and return types

$fids is a fids
$return is a reference to a hash where the key is a fid and the value is an annotations
fids is a reference to a list where each element is a fid
fid is a string
annotations is a reference to a list where each element is an annotation
annotation is a reference to a list containing 3 items:
	0: a comment
	1: an annotator
	2: an annotation_time
comment is a string
annotator is a string
annotation_time is an int

Command-Line Options

-c Column

This is used only if the column containing the subsystem is not the last column.

-i InputFile [ use InputFile, rather than stdin ]

Output Format

The standard output is a tab-delimited file. It consists of the input file with extra columns added.

Input lines that cannot be extended are written to stderr.
