CWR - Common Works Registration

Hello,

I'm new to MusicBrainz and have been evaluating it for possible use in a project. 

I notice that the works data is very thin in comparison to the number of recordings (over 13 million recordings, but less than 500 thousand works). It seems this could be improved a great deal by implementing an import for CWR - Common Works Registration. CWR is being used by publishers and societies around the world to register and exchange information about musical works. 

Here is the specification document:

http://www.commonworksregistration.com/CisacPortal/downloadMyRessource.do?fileName=/home/ftpdata/FileRepository/IS-CRF/EN/IS-CRF08-0027R5_CWR_Functional_Specifications_2005_08_04_EN.doc&name=IS-CRF08-0027R5_CWR_Functional_Specifications_2005_08_04_EN.doc

It would not be necessary to implement the entire specification, only the parts relevant to the MuicBrainz database. 

Would this be useful for the MusicBrainz project? If so, would it be acceptable to implement in a language other than Perl? My first choice would be PHP and I assume that could be easily called from Perl to process CWR files.

Thanks,

John DeSoi, Ph.D.
