Data interchange problems come in all sizes
I had a pretty small data interchange problem the other day: I just wanted to archive some play lists that I had compiled using various music player daemon (mpd) clients. The mpd server stores playlists as simple m3u files,...

Once more into Versioning -- this time with HTML
The W3C TAG has worked on the general issue of "versioning" for many years, and many TAG members may be worn out on the issue. However, undeterred by past history, I'm taking another run at it, this time trying to...

Caching XML data at install time
The W3C web server is spending most of its time serving DTDs to various bits of XML processing software. While XSLT processors such as xsltproc and Xalan have no technical dependency on the XHTML DTDs, I suspect they're used with XHTML enough that shipping copies of the DTDs along with the XSLT processing software is a win all around.

Syntax for ARIA: Cost-benefit analysis
The ARIA spec. defines roles, states and properties to manage the interface between rich web documents and assistive technologies. The primary expression of roles, states and properties in markup languages is via attributes. ARIA has to specify how its vocabulary of attributes and values can be integrated into both existing and future languages. This analysis assesses alternative approaches to ARIA syntax.

Simple things make firm foundations
You can look at the development of web technology in many ways, but one way is as a major software project. In software projects, the independence of specs, has always been really important, I have felt. A classic example is...

Version Identifiers Reconsidered
The Architecture of the World Wide Web includes a section on extensibility and versioning of languages and data formats. The TAG is having second thoughts about the suggestion that all data formats SHOULD provide for version identification. Sometimes it is a good thing to do, but sometimes not.

When to standardize, especially an RDF API
The HTML 4.01 specification has an IMG element, but there is no normative dependency on the PNG or GIF or JPEG specifications. "What good is an HTML user agent that doesn't support GIFs?!?" you might ask. And you wouldn't be...
