RE: [xml-dev] RE: XML design for converting to and from JSON?

["Michael Steidl \(IPTC\)" <mdirector@iptc.org>]

Hi all,

to throw in a view from a long-time XML user: 
IPTC - www.iptc.org - builds XML-based news exchange formats for 17 years
now and was also challenged to do the same in JSON. After a long discussion
we refrained from automatically converting an existing XML data model to
JSON:
- currently no shared/common way to deal with namespaces in JSON
- designs like inline elements don't exist in JSON
- the element/attribute model has no corresponding design in JSON
- and a basic requirement of JSON users is: no complex data model, please!

Therefore we created 
- a simplified data model for the news exchange in JSON - www.newsinjson.org
- compared to the richer but also more complex XML format www.newsml-g2.org
- a highly corresponding JSON model to an initial XML model for the rights
expression language ODRL as this is a set of data which cannot be
simplified: http://www.w3.org/community/odrl/work/json/ vs
http://www.w3.org/community/odrl/work/2-0-xml-encoding-constraint-draft-chan
ges/

Both approaches were welcome and are used - and we learned: an XML-to-JSON
tool only is of limited help.

Best,
Michael
