My 2 cents:
* don't specify a MARC-in-Whatever format: define the way you store the
MARC record in memory then just use dumpers from the YAML, JSON, and
other serialization systems.
* marc-in-json itself (as described in the document) use dicts at every
level which leads to 2 issues:
* implementations of transformations and querying are painfull
* explicit use of useless keys = more useless data (not as crappy as
XML but still useless.
MARC::MIR http://search.cpan.org/~marcc/marc-mir-0.4/lib/MARC/MIR.pod
In-memory representation is much simpler to handle, whatever the
programming langage you use.
As comparaison, the same record in MARC::MIR and MIJ.
