Semantic Web

sparta.py 0.8

I’m happy to announce that version 0.8 of sparta, a simple API for RDF, is now available. As always, feedback and suggestions are appreciated.

Adding Semantics to Excel with Microformats and GRDDL

When I worked in the financial industry, I quickly noticed that Excel spreadsheets contain the bulk of the data in the enterprise. It may make IT execs tear their hair out, but having the data nearby and ready for analysis is sloppy, but oh-so-effective. The challenge is to make the data reusable elsewhere.

(Statistical) Information Wants to Be Free

The Australian Bureau of Statistics has announced that as of today, their online publications and tables are now free to download, instead of requiring an account and a per-download charge, as before.

Data Modeling and Abstraction

Today’s release of Tiger includes a new but little-discussed framework for developers, CoreData. What’s most interesting to me is its similarities — and differences — to SDO, IBM and BEA’s* effort to abstract away the specifics of how data is stored.

Can Somebody Explain to Me...

RDF has a simple, usable, universal model; everything’s nodes and arcs, so it avoids the problems of the Infoset, which IMO are brought by its complexity and special cases. Years of disquiet about attributes by portions of the XML cognoscenti support this view unintentionally, I think.

Sparta.py 0.7

I’m happy to announce that version 0.7 of sparta.py, a simple API for RDF, is now available. As always, feedback and suggestions are appreciated.

Sparta.py 0.6: RDF (and RSS!) Made Easy

Version 0.6 of sparta.py is now available. Changes include:

sparta.py 0.5: RDF made easy

Version 0.5 of sparta.py is now available; with this release, I think it’s roughly feature-complete.

XML Infoset, RDF and Data Modelling

I’ve been talking with a few people about my previous assertion that the Infoset is a bad abstraction for data modelling, and my subsequent post about the informational properties of the Infoset.

sparta.py 0.4: Data Binding for RDF in Python

After a short pause (OK, nearly three years), I’ve released version 0.4 of sparta.py.

Madonna Dead

This is why heuristics aren’t such a hot idea.

The Semantic Web’s Dirty Little Secret

Browse through the W3C Semantic Web pages and you’ll see this notice in a few different forms:

The New RDF

I spent a little time on the plane the other day reading the latest WD of the RDF Primer. I didn’t attempt to review the entire document set, as reading a 71 page primer is quite enough!

Real-World RDF

Jo Walsh has created a Semantic Web system that appeals quite strongly - a means of using RDF to map to the real world in “gonzo geographical data collection”.

We need WikiVerbs!

Before, I was wondering about the intersection of Wikis and the Semantic Web. I’ve since done some noodling and prototyping, and the idea came together on the train home tonight.

Wiki as Semantic Web?

Anybody else notice how you can use a Wiki like a Semantic Web engine?

RDF Model and Syntax

Jack William Bell makes a precise, short and readable effort at explaining why RDF is simple and important.
