RDFX

Thanks to Danny this morning I came across RDFX, an RDF plugin for Eclipse. The howto document includes some interesting screenshots, based around exploring a FOAF document. To install the plugin I found that I had to follow a few different steps (I'm currently using an Eclipse 3.0.0 integration build; 200309100800 to be precise) that … Continue reading RDFX →

Jena 2 Upgrade

Just a quick note to say that I upgraded the FOAF-a-Matic Mark 2 to use Jena 2.0.0-beta1 and found the migration pretty painless. I'd read Shelley's Jena week articles as preparation so had a good idea about what I needed to do. For the most part it was just changing imports, and switching to use … Continue reading Jena 2 Upgrade →

FOAF Concerns, revisited and discussed

Shelley Powers has posted a list of concerns that she has with FOAF as currently defined and used: Practical RDF: Danger, Will Robinson: Part 2 To summarise, these are: Inappropriate use of Myers Briggs propertyWhat does foaf:knows mean?Social implications of foaf:knowsPublishing data about other people For more details on each see Shelley's post. These set … Continue reading FOAF Concerns, revisited and discussed →

Dynamic Languages and Linking

Ted Leung points to some interesting comments from Jon Udell and Don Box about Dynamic languages, virtual machines, information clients, and more. This is related to some musings of my own, which, as you can see from the stream of consciousness style of the Wiki page, may not be coherently expressed at the moment, but … Continue reading Dynamic Languages and Linking →

FOAF-a-Matic Translations: More Coming, and How It Works

I've just added a comment to Danny's "Translator exchange for open projects" LazyWeb entry, asking for additional translations of the FOAF-a-Matic. Having a simple bulletin board like this is a great idea. Here's hoping that it gets some more linkage and pulls in more project requests and translators offering their services. I've already followed-up Diane … Continue reading FOAF-a-Matic Translations: More Coming, and How It Works →

FOAF and Privacy

Shelley Powers has been writing about FOAF this week, privacy issues in particular. Ben Hammersley has been having similar thoughts. This is all good. As I understand it one of the aims of FOAF and related vocabularies (FOAF has no 'built-in' notion of trust) is to help explore these kind of issues. Control over what … Continue reading FOAF and Privacy →

MP3 GPS

Here's something I came across whilst looking for a Java API into WinAmp. Why was I looking for a such a beast? Well mainly because I'm a Java weenie and can't be bothered to dredge up the bits of C/C++ I know to write WinAmp plugins properly. The plugin I'm thinking about would be used … Continue reading MP3 GPS →

Ping FOAFnaut

Here's a simple bookmarklet that uses FOAF Autodiscovery to find a FOAF document linked to from the page you're currently viewing and then submits it to FOAFnaut. If FOAFnaut already knows this URL then the database will be cleared and the data reloaded, otherwise it will just load the new data. Just drag the link … Continue reading Ping FOAFnaut →

My Life in RDF

I have this project idea at the back of my mind which I mentally refer to as "My Life in RDF". Rather than being an exciting diary of the trials and tribulations of a lone hacker, wrestling with semantic web technologies for fun and profit, you should read that title a bit more literally: the … Continue reading My Life in RDF →
