Hash URIs
There's been quite a bit of discussion recently about the use of hash-bang URIs following their adoption by Gawker, and the ensuing downtime of that site. The TAG at the W3C have also been drafting a document on Repurposing the Hash Sign for the New Web which takes a rather wider view than just the hash-bang issue, and on which they are seeking comments.
All matters of design involve weighing different choices against some criteria that you decide on implicitly or explicitly: there is no single right way of doing things on the web. Here, I explore the choices that are available to web developers around hash URIs and discuss how to mitigate the negative aspects of adopting the hash-bang pattern.

New opportunities for linked data nose-following
For those of you interested in deploying RDF on the Web, I'd like to draw your attention to three new proposed standards from IETF, "Web Linking", "Defining Well-Known URIs", and "Web Host Metadata", that create new follow-your-nose tricks that...

The Mission of W3C
I've now been with W3C for almost three months. My first priority was to meet with the global stakeholders of the organization. I began with W3C membership. Through meetings, phone calls, technical conferences, and informal sessions I've met upwards of...

Why does the address bar show the tempolink instead of the permalink?
An important feature of HTTP is the temporary redirect, where a resource can have a "permanent" URI while its content moves from place to place over time. For example, http://purl.org/syndication/history/1.0 remains a constant name for that resource even though its...

Default Prefix Declaration
In this posting, my intention is to provide a concise statement of an idea which is neither
particularly new nor particularly mine, but which needs a place that can be referenced in the context of the current debate about distributed extensibility and HTML5. It's a very simple proposal to provide an out-of-band, defaultable, document-scoped means to declare namespace prefix bindings.

Orthogonality of Specifications
HTTP,HTML,URI The general principle of platform design is that platforms consist of a set of standard interfaces. Standard interfaces allow substitution of components across the interface boundary, while independence of interfaces allow evolution of the interfaces themselves. In a PC,...

Language semantics and operational meaning
W3C and other standards organizations are in the business of defining languages -- conventions that organizations can choose to follow -- and not in mandating operational behavior -- telling organizations and participants in the network how they are supposed...

Once more into Versioning -- this time with HTML

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.

The details of data in documents: GRDDL, profiles, and HTML5
GRDDL, a mechanism for putting RDF data in XML/XHTML documents, is specified mostly at the XPath data model level. Some GRDDL software goes beyond XML and supports HTML as she are spoke, aka tag soup. HTML 5 is intended to...

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.

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.
