I started this essay last week on the train between Bath and Oxford, but then got side-tracked with writing up my XTech 2005 submissions and fighting off a nasty stomach bug before finishing it. Poking into my aggregator this morning I was interested to see this exchange between Bill de h

Views in Triple Stores
Views are an important feature of relational databases, providing a way to abstract over complex queries, subset data to just the minium required for a given task, as well as providing a point around which a schema can be refactored without having to (immediately) change the applications that use it. So far I'm not aware … Continue reading Views in Triple Stores
FOAF from Audiscrobbler
Whilst upgrading my Audioscrobbler WinAmp plugin today to be conformant to the latest submission protocol (my RESTful redesign didn't gain any traction unfortunately) I discovered that they're been busy on their web services interface. Alongside the original RSS 1.0 "recent tracks" feed, there is now an RSS 2.0 feed, a plain text version, and a … Continue reading FOAF from Audiscrobbler
IngentaConnect RSS Feeds
It's with some pleasure that I'm able to announce a little Xmas present from the technology team at Ingenta to the academic and RDF communities: another batch of RSS feeds from IngentaConnect. To be precise: in excess of 20,000 new RSS feeds containing the latest table of contents data for the academic journals that are … Continue reading IngentaConnect RSS Feeds
FOAF-a-Matic now available in Dutch and Chinese
I'm pleased to announce that the FOAF-a-Matic is now available in two additional languages: Traditional Chinese and Dutch. (Those are the direct links, content negotation will be used to give you a suitable version automatically if you use the usual link). I actually got sent two Chinese translations so I should thank both Ilya Eric … Continue reading FOAF-a-Matic now available in Dutch and Chinese
Slug: A Simple Semantic Web Crawler
Back in March I was tinkering with writing a Scutter. I'd never written a web crawler before, so was itching to give it a go as a side project. I decided to call it Slug because I was pretty sure it'd end up being a slow and probably icky; crafting a decent web crawler is … Continue reading Slug: A Simple Semantic Web Crawler
foaf-beans 0.1
I'm pleased to announce the first iteration of a Java API for FOAF based around the Jena semantic web toolkit. The API, which I've dubbed "foaf-beans", is an attempt to provide a number of convenience classes that will allow Java developers to quickly get to grips with reading and writing FOAF data. With this in … Continue reading foaf-beans 0.1
Chaals on Schema Documentation
This is an interesting posting from Charles McCathieNevile to the rdf-interest group discussing how to correctly document an RDF Schema. Basically: Ensure that the terms are annotated with labels and comments Flag annotations with their language code, and seek translations into other languages Use SKOS or custom properties to embed actual examples in the schema … Continue reading Chaals on Schema Documentation
del.icio.us and foaf:interest
Using the foaf:interest property it's possible for me to describe my interests (musical, technical, etc) in my FOAF profile. The term has been specified so that it has a range of foaf:Document, with the implication that the foaf:topic of that foaf:Document is what I'm interested in. Seem a bit convoluted? Maybe, but there are benefits... … Continue reading del.icio.us and foaf:interest
Public Collections of RDF
Bob DuCharme is looking for public collections of RDF. He's compiled an initial list and is looking for further examples of, ideally large, data sets.
