[Koha-devel] RFC : Local cover images

[Eric Bégin]

  Hi Koustabha,

If we are going to keep information in a MARC field, why not put the 
file name directly.  That way, it doesn't have to be only a number, I 
could have HarryPotter_V1.jpg or even a remote path.

I looked up the MARC standard and it would make sense to store the path 
to the file in the 856$u field, specifying Image (or Cover) in the $3 
field.  There is such an example in
http://www.loc.gov/marc/authority/ad856.html.

*856* 
*4#**$3*image*$u*http://www.ibiblio.org/wm/paint/auth/vinci/joconde/joconde.jpg

A syspref could also be added for a base directory in which are located 
the files.

My 2 cents,

Eric
