Re: [xml-dev] The JSON Data Interchange Format (ECMA standard, October 2013)

Hi Roger,

I think JSON is fine for some scenarios, XML for others and there is even a
intersection set.

DataPower appliance started as XSLT accelerator more than 10 years ago.
Because there are customer scenarios needing JSON processing capabilities
JSON processing support was added back in 2009.

Since DataPower needed XML a new XML representation standard (JSONX) was
defined IBM internally (DB2 and DataPower teams).
It was submitted externally but expired:

So JSON->JSON processing was done by
JSON->JSONX->your XSLT->JSONX->xform(store:///jsonx2json.xsl)->JSON
with a shipped stylesheet.

Since June this year DataPower provides an XQuery compiler in addition.
And because of the JSON demand "JSONiq Extension to XQuery" compiler is
provided, too.
See "JSONiq Extension to XQuery" and "Implementations" tab:

The Zorba XQuery/JSONiq processor provides free online evaluation tool
under try.zorba.io.
There are many XQuery and JSONiq samples to play with, and I really like
the "Share" button:

DataPower does not support JSONiq "update" functionality currently.
But a XSLT copy template like solution is possible with JSONiq, too:

Hi Folks,

ECMA has just published: The JSON Data Interchange Format [1].

The specification is 5 pages long. In those 5 pages there are lots of large

Here are some interesting snippets:

		 JSON is a lightweight, text-based,
		 language-independent data interchange
		 format. It was derived from the ECMAScript
		 programming language, but is programming
		 language independent.

		 JSON is a text format that facilitates structured
		 data interchange between all programming

		 Because it is so simple, it is not expected
		 that the JSON grammar will ever change.
		 This gives JSON, as a foundational notation,
		 tremendous stability.

		 It is expected that other standards will refer
		 to this one... Such standards may require
		 specific behaviours. JSON itself specifies no

		 JSON was inspired by the object literals of

		 JSON is agnostic about numbers. In any
		 programming language, there can be a variety
		 of number types of various capacities and
		 complements, fixed or floating, binary or
		 decimal. That can make interchange between
		 different programming languages difficult.
		 JSON instead offers only the representation
		 of numbers that humans use: a sequence of
		 digits. All programming languages know how
		 to make sense of digit sequences even if they
		 disagree on internal representations. That is
		 enough to allow interchange.
