How to use just part of field as identifier

[tuxedobyrd]

I have some records in Omeka that describe multiple items in our collection. For example, I have one record for an interview that is on two tapes with a transcript and so I have three DC:Identifier fields with the object ID numbers we use locally for the items and a parenthetical explanation. The fields are "2001.037.0017 (Tape 1)", "2001.037.0018 (Tape 2)", and "2001.037.0001 (Transcript)".

What I would like to do in cases like this is have just the number part from the first identifier be the clean url, so my clean url would be "example.com/collection_identifier/2001.037.0017" but I still want the parenthetical part to display on the items page. It seems like I should be able to simply modify the $sqlSelect line in the GetRecordIdentifier.php file so that it selects only the part of the string before the first space (if a space exists). I have tried to use strtok and a few other functions to accomplish this, but just can't seem to get it done. Any nudge in the right direction would be greatly appreciated.

I am not using prefixes so there is no complication there.

Hi,

On my point of view, the simplest is to add another id with a prefix:

Tape 1: 2001.037.0017

or

Document: 2001.037.0017

so there is no need to hack and this avoids possible future issues when the dc:identifier will be reordered, for example if somebody wants to set the transcription as the first dc:identifier. And there should be a different identifier for the item as a whole and each part of it in order not to be confused (so the main id should not be 2001.037.0017).

To keep the same data, a new option should be added to the plugin to use a suffix ((Tape 1) here), but it means some work: everywhere you find "prefix" in the plugin, add some code to use a "suffix"...
