Has JSON pretty much replaced XML for string processing for the web, or are there use cases where XML is still necessary?
It’s replaced XML as the default format for most APIs. XML is still necessary for Atom/RSS feeds and other existing standards built on top of XML. It’s also a better choice than JSON for markup-style data—stuff like XHTML where tags are applied to sequences of characters within larger chunks of text.

I think the Web community has spoken, and it’s clear that what it wants is HTML5, JavaScript and JSON. XML isn’t going away but I see it being less and less a Web technology; it won’t be something that you send over the wire on the public Web, but just one of many technologies that are used on the server to manage and generate what you do send over the wire.

Introducing BERT and BERT-RPC. Justification for inventing a brand new serialisation protocol: Thrift and Protocol Buffers both use IDLs and code generation, XML “is not convertible to a simple unambiguous data structure in any language I’ve ever used” and JSON lacks support for unencoded binary data. The result is BERT—Binary ERlang Term—which extracts a format from Erlang in much the same way that JSON extracted one from JavaScript. # 21st October 2009, 10:11 pm
With YQL Execute, the Internet becomes your database. This is nuts (in a good way). Yahoo!’s intriguing universal SQL-style XML/JSONP web service interface now supports JavaScript as a kind of stored procedure language, meaning you can use JavaScript and E4X to screen-scrape web pages, then query the results with YQL. # 29th April 2009, 10:50 pm
A few notes on the Guardian Open Platform
This morning we launched the Guardian Open Platform at a well attended event in our new offices in Kings Place. This is one of the main projects I’ve been helping out with since joining the Guardian last year, and it’s fantastic to finally have it out in the open.
[... 839 words]JsonML (JSON Markup Language). An almost non-lossy serialization format for sending XML as JSON (plain text in between elements is ignored). Uses the (element-name, attribute-dictionary, list-of-children) tuple format, which sadly means many common cases end up taking more bytes than the original XML. Still an improvement on serializations that behave differently when a list of children has only one item in it. # 10th February 2009, 3:03 pm
XML is better if you have more text and fewer tags. And JSON is better if you have more tags and less text. Argh! I mean, come on, it’s that easy. But you know, there’s a big debate about it.

CouchDB, XML, and E4X. Brilliant—CouchDB now enables SpiderMonkey’s E4X support, meaning CouchDB views can easily query XML documents stored inside JSON objects using E4X syntax. # 5th March 2008, 12:31 am
[Release] CouchDB 0.7.0. This is a huge milestone for the project—it’s the first official release to include the JSON REST API instead of XML, and it’s also the first release that is “intended for widespread use”. # 17th November 2007, 12:25 am

Apache Solr 1.1. Solr is the search Web Service built on top of Lucene. The latest release introduces JSON, Python and Ruby response formats in addition to XML. # 13th January 2007, 1:16 am
Seems easy to me; if you want to serialize a data structure that’s not too text-heavy and all you want is for the receiver to get the same data structure with minimal effort, and you trust the other end to get the i18n right, JSON is hunky-dory.

Why JSON isn’t just for JavaScript
Dave Winer’s discovery of JSON (and shock that “it’s not even XML”) has triggered an interesting discussion thread, on his blog and elsewhere. Plenty of people have re-assured him (and themselves) that it’s only used for JavaScript—it’s convenient in the browser but irrelevant elsewhere.
[... 787 words]I read on Niall Kennedy that del.icio.us has come up with an API that returns a JSON structure, and I figured, sheez it can’t be that hard to parse, so let’s see what it looks like, and damn, IT’S NOT EVEN XML! [...] Who did this travesty? Let’s find a tree and string them up. Now.
