PrinceXML is extremely impressive. I had a poke at Prince (a commercial package for generating high quality PDFs from HTML, XML, CSS and SVG) a few weeks ago and was similarly impressed. # 8th February 2008, 12:02 pm

Cross-Site XMLHttpRequest (via) “Firefox 3 implements the W3C Access Control working draft, which gives you the ability to do XMLHttpRequests to other web sites”—you can mark a document as available for cross-domain requests using either an Access-Control HTTP header or an XML processing instruction. # 9th January 2008, 11:57 pm

[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

The larger question is why on earth, in 2007 and ten years after XML came out, we are still using text files that don’t label their encoding?

XForms in Firefox (via) Practical tutorial on taking advantage of the Firefox XForms plugin, sadly not yet bundled with the browser itself. # 26th January 2007, 9:59 am

Which is the real explanation of where the name XMLHTTP comes from- the thing is mostly about HTTP and doesn’t have any specific tie to XML other than that was the easiest excuse for shipping it so I needed to cram XML into the name (plus- XML was the hot technology at the time and it seemed like some good marketing for the component).

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.

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.

More YAML

Paul Tchistopolskii’s XML Alternatives reminded me to take another look at YAML. The specification has been updated since I last looked and seems to be a bit more complicated, but it’s still a very nicely designed format. Implementations are available for Perl, Python and Ruby with C and Java on the way but strangely no one seems to be doing one for PHP yet. I’m doing a course at Uni on compilers at the moment which includes quite a lot of stuff about writing parsers so I’m very tempted to have a go at a YAML implementation in the next few weeks just to try stuff out. The possibility of easily swapping relatively complex data structures between PHP and Python is pretty tempting as well.

XML security on SitePoint

Getting Started with XML Security is a SitePoint article of epic proportions. I had never really looked at any of the XML security applications but this article appears to cover the lot.

xmlhack news wire

xmlhack’s “Editor’s Newswire” is interesting. It is a small column (explained here) located on the right hand side of the site that displays the latest XML news snippets “in real time”. The interesting part is how the section is updated—an IRC bot (The Daily Chump Bot, written in Python) monitors a channel for specific commands from authorised users, and produces an XML file of new snippets. Site updates through IRC (or instant messenging services such as MSN or Jabber) is a concept which we could see a lot more of, especially in this age of web services.
