The birth of XML

Written in 1999, this article is not prime news but it’s still a must read for anyone interested in XML: in this short buzzword free piece, XML’s father, Jon Bosak, describes the birth of his baby.

Web 2.0 at XML Prague

This coming week-end, I’ll have the pleasure to be at XML Prague, a small and friendly XML conference in a wonderful city.
This year, I’ll leave out my usual XML schema languages expert hat to speak on two topics:

An experience to define a RDF/XML Query By Example language. This presentation relates a very cool project that [...]

Edd Dumbill on XTech 2006

Last year Edd Dumbill, XTech Conference Chair, had been kind enough to answer my questions about the 2005 issue of the conference previously known as “XML Europe”. We’re renewing the experience, taking the opportunity to look back at last year issue and to figure out how XTech 2006 should look like.
vdV: You mention in your [...]

TreeBind, Data binding and Design Patterns

I have released a new version of my Java data binding framework, TreeBind and I feel I need to explain why I am so excited by this API and by other lightweight binding APIs…
To make it short, to me these APIs are the latest episode of a complete paradigm shift in the relation between code [...]

TreeBind: one infoset to bind them all

This is the first entry of a series dedicated to the TreeBind generic binding API.
I have recently made good progress in the extensive refactoring of TreeBind required by my proposal to support RDF and it’s time to start explaining these changes.
The first of them is the infoset on which TreeBind is now relying.
TreeBind’s target is [...]

TreeBind goes RDF

TreeBind can be seen as yet another open source XML <-> Java object data binding framework.
The two major design decisions that differentiate TreeBind from other similar frameworks are that:

TreeBind has been designed to work with existing classes through Java introspection and doesn’t rely on XML schemas.
Its architecture is not specific to XML and TreeBind can [...]

SPARQL Versus Versa

A new working draft of SPARQL has been released.
While there is no doubt that the language is getting better and more polished with each new release of this specification, I am surprised to see that the limitations I had found in rdfDB back in early 2001 when I have tried to use it for XMLfr [...]

Edd Dumbill on XTech 2005

XTech 2005 presents itself as “the premier European conference for developers and managers working with XML and Web technologies, bringing together the worlds of web development, open source, semantic web and open standards.” Edd Dumbill, XTech 2005 Conference Chair answered our questions about this conference previously known as XML Europe. This interview has been published [...]

Tim Berners-Lee has taken up the hatchet

Tim Berners-Lee takes up the hatchet and publishes use cases for relative URIs as namespace names:
I can’t remember what prompted me to write up these sue cases [sic] for relative URIs in namespaces, and I apologize if I have done it before. The XML 1.0 and XML 1.1 namespaces documents “deprocate” this practice, following a [...]

RDF Query Languages

I am thinking about writing a RSS aggregator. Not that it is original or has never been done, but just as an exercise to play with a RDF database and so far I am still not convinced of the way to go!
As a query language, I really like Versa, but RDQL seems like having much [...]
