Announcing Giblet

Excerpt: Giblet allows the creation of simple RDF files, based on available RDF schemata. It runs as a Javascript application in an enabled browser.

Site Redesign

Excerpt: If you can read this then your DNS has picked up our server change. We've also given the site a new look, retired some areas that were past their sell-by date and dusted off a few things that were lurking in the background.

A basic RDF XML validation stylesheet

Excerpt: By James Carlyle. I've put together a basic XSLT 1.0 stylesheet to validate RDF in XML. It has been tested against all the simple negative tests in the W3C RDF test suite. It produces no output for all the positive tests (i.e. it finds them all valid), and produces output for all the negative tests (i.e. it finds them all invalid). The output from the stylesheet looks something like this: # ERROR <rdf:ID rdf:resource="http://example.org/node2"/> # ERROR rdfms-rdf-names-use/error013.rdf : ID is forbidden as a property element name. There is a simple error message (taken from the test case) and a snippet of the original document to help provide some context. The checks are specified using XPath expressions. If I've misunderstood the RDF/XML syntax specifications, these …

Comment Spam

Excerpt: We, like many others, have been inundated with comment spam in recent weeks. Dealing with this is a complete waste of our time so we've had to make some changes. We're never going to be able to prevent spammers from posting comments. Every method I've seen suggested removes functionality that is genuinely required for comment systems - we should encourage the publishing of links, not prevent them and anonymous posting is required in certain circumstances. So, we have to let the spammers in and deal with the mess they make. And rather than relying on the bottleneck of James and I, we need to open up so that everyone can contribute to the quality of the content here. So, we've decided …

Launch of sw-announce Mailing List

Excerpt: sw-announce is a moderated announcements-only mailing list. The list is intended to efficiently communicate news relevant to the Semantic Web and related technologies. This includes, but is certainly not limited to, metadata, ontologies, RDF, knowledge management, AI, electronic agents, and semantic web services.

Category RSS Feeds and RDF Versions

Excerpt: Each category now has its own RSS 1.0 feed linked at the top of the category archive (e.g. the RDF Templates Design Notes category). Additionally, most pages now have RDF Versions with full machine-readable metadata.

Semantic Web News Aggregator

Excerpt: We've been running a little semantic web news aggregator here for a while, but somehow forgot to actually link to it from anywhere on the site. It gathers RSS from various semweb related sources every hour or so. I've now linked it in the top menu of each page on the site: sw news. If you know of any other sources you want to add, just drop me a line: <iand at internetalchemy.com>.

Add Your Source

Excerpt: You can now submit your own sources to the source catalog. We should be along to index and analyse it shortly after.

Networks of Things

Excerpt: I've just added a new feature to the list of sources. Each source lists some of the things that are described in that source document. Now, each of these has a link that lets you see what other sources are describing the same thing. For example, if you look at the entry for my FOAF you'll see some of the people I know. Next to each of them is an [other sources] link which takes you to a list of other sources that refer to those people. Here's the list of sources that refer to Mark Pilgrim. At the moment the spider is looking for People, RSS channels and Documents so you can explore the networks between these resources. I'll explain …

New Weblog

Excerpt: All good sites should have a weblog to keep its visitors up todate with what's happening on the site and in the industry, so today marks the launch of ours. More to come soon…
