[uf-new] hAlbum concerns

[Justin Maxwell]

Hello Martin and Andy (sending again since my mime-type prevented the  
email from showing up in the digest/archives),

Thanks for your responses.

  I would recommend Discogs as a massive source of useful examples:

http://discogs.com
example of physical album: http://www.discogs.com/release/530022
example of mp3-only (digital) release: http://www.discogs.com/release/ 
786894

(Note that even the digital release employs a catalog ID/value.)

If there is any way I can help expedite or assist your process, or  
perhaps join the contributors roster, please let me know.  In the  
meantime, I've been using class="identifier" for the catalog number  
and class="position" for the track number.

Since those other than catalogue number are proprietary  
identification methods, i.e., identifers for external systems, the  
role of "identifier" should go to the primary source, the record  
label or publisher.

Best,
Justin Maxwell
