Jangle is more of a delivery mechanism than a format -- once you know 
'jangle' you know how to access data, but the data can still be in any 
format at all.  Including, say, the NISO format.  So it's different in 
that case from the NISO stuff which specs both delivery mechanism and 
data format.

When it comes to actual data formats, you've still got to choose with 
Jangle.  And the choices are.... kind of weird and not always optimal.  
But another one to pay attention to in addition to z39.50 (ie MARC, or 
OPAC-MARC) or NISO is the DLF ILS-di task force "dlf expanded" format.

My trials and tribulations at trying to use standard formats through a 
jangle-like mechanism (but not actually jangle yet) can be found here:
