[Clipart] clipart Digest, Vol 47, Issue 16

[Greg Bulmash]

If it's agreed that all instances where "birds" occurs should be
"bird", then the most efficient method is to do an SQL query to remove
"birds" from any image where the author submitted both "bird" and
"birds" (this may require a script depending on how things are laid
out), then another to change all instances of "birds" to "bird".

But this doesn't stop users from entering birds on future uploads.
There needs to be a remap function in the tag registration module that
compares each new tag to a list and "adjusts" it if it's a mapped
term.

For example...

$tag = "birds";
$newtag = remaptags($tag);
// insert $newtag into database

.....

function remaptags($tag){

  $mapped = array( "birds" => "bird",
                             "clowns"=> "clown"
                             "Father Christmas" => "Santa Claus");

 if(isset($mapped["$tag"])) $tag = $mapped["$tag"];
 return $tag;
}

If you want to update the mapping, just add to or change that array.
This way an editor doesn't have to go through and run the remapping
processes every so often to combat tag drift.  You could also use a
similar function to broaden tags.  For example you might want to make
sure that every image that gets tagged "Father Christmas" also gets
tagged "Santa Claus" and vice versa.
