Over the weekend, I set about to rip out the last of the RDF from this site. Then I changed my mind.

RDFa for DocBook?http://norman.walsh.name/2009/09/22/RDFaForDocBook2009-09-22T13:20:39Z2010-10-08T18:40:53.786955ZDocBookRDFXMLSummerSchool2009

Adding RDFa to DocBook would make it possible to add a class of semantic annotations to DocBook without changing the schema. But is that a good idea?

XML+XQuery+Google Voice+Python=WIN!http://norman.walsh.name/2009/09/01/gvcall2009-09-01T13:45:54Z2010-10-08T18:40:43.663475ZGoogleVoiceMarkLogicRDF

It's finally possible to put all the pieces together.

Hacking httpRange-14.

PIM Examplehttp://norman.walsh.name/2005/12/16/pimExample2005-12-16T17:36:44Z2010-10-08T18:16:42.458563ZRDF

An example of how I use the vCard ontology and all this XML+RDF stuff.

Extracting vCards from hCard markuphttp://norman.walsh.name/2005/12/12/vcard2005-12-12T23:48:35Z2010-10-08T18:16:39.239695ZRDF

Another attempt at refining the ontology that I've been working on for modelling vCard data in RDF. This time with a GRDDL transformation to extract RDF from hCard markup.

Modelling vCards in RDFhttp://norman.walsh.name/2005/12/05/vcard2005-12-06T03:40:37Z2010-10-08T18:16:25.449176ZRDF

Yet another stab at modelling names and addresses.

An address book ontology (take 2)http://norman.walsh.name/2005/11/30/contacts2005-11-30T15:13:27Z2010-10-08T18:16:13.00352ZLazywebRDF

More thoughts on modelling names and addresses.

Modeling names and addresses. No, not that old debate, the sort that appear in your address book.

Blog Housekeeping: SKOS Taxonomyhttp://norman.walsh.name/2005/06/01/skos2005-06-01T18:07:55Z2010-10-08T18:12:37.445243ZRDFSelfReference

I've done a bit more housekeeping. None of this should be significant to the casual visitor, nor even visible for the most part.

JpegRDF: JPEG Metadata in RDFhttp://norman.walsh.name/2005/projects/jpegrdf2005-04-27T10:40:05Z2010-10-08T18:17:48.24981ZJavaPhotographyProgrammingRDF

This is the permanent status page for JpegRDF. JpegRDF is an application for extracting, storing, and updating RDF metadata about JPEG images. Version 2.3.0, with support for the MakerNote field from Canon cameras, is now available.

RDF Twig: XSLT Extension Functions for Accessing RDF Graphshttp://norman.walsh.name/2004/projects/rdftwig2005-04-25T11:27:07Z2010-10-08T18:07:13.34542ZJavaProgrammingRDF

This is the permanent status page for RDF Twig. RDF Twig is a set of XSLT extension functions for Saxon and Xalan that provide dynamic access to RDF graphs stored in the Jena repository. Version 0.96, supporting the Saxon 8.4 API, is now available.

Tagback: Joining the Folksonomy Frayhttp://norman.walsh.name/2005/02/20/tagback2005-02-20T17:47:20Z2010-10-08T18:08:54.684408ZRDFSelfReference

I've added provisions for folksonomy tags and plan to adopt them as a replacement for threads.

I’ve been offline for several days, visiting with my folks, taking pictures, relaxing. I’ve also been hacking a bit with the way foaf:depicts is used on this site.

A Topic Map for norman.walsh.namehttp://norman.walsh.name/2004/09/08/topicmap2004-09-08T21:17:55Z2010-10-08T18:02:40.965743ZBalisageExtreme2004RDFTopicMaps

RDF and Topic Maps cover a lot of the same territory. This essay exposes a first attempt at building a Topic Map for the contents of this site. It models only a few topics and associations and it probably models them badly.

Is RDF/XML Good for Anything?http://norman.walsh.name/2004/07/30/rdfxml2004-07-30T12:27:55Z2010-10-08T18:01:25.044167ZRDFXML

Having a standard transfer syntax for RDF is great. XML is an ideal format for this sort of “core dump”: it’s amenable to machine processing and it’s possible for a human being (with sufficient skill, experience, and dedication) to look at it in a text editor and “figure it out”. So RDF/XML is good for RDF core dumps. But is it something users should be writing by hand? I’m not sure.

Is It the APIs, Stupid?http://norman.walsh.name/2004/06/14/apis2004-06-14T21:15:00Z2010-10-08T17:59:40.815288ZDocBookProgrammingRDF

You’ve got your regular expressions, your SAX, and your DOM, you’ve even got your RDF as an XML API (I’m not kidding). And now you’ve got another choice in the Java platform. Some thoughts on APIs.

Summer Flowers and Metadatahttp://norman.walsh.name/2004/06/07/flowers2004-06-07T20:17:00Z2010-10-08T17:59:26.995228ZFlowersPhotographyRDF

It’s early summer here in Massachusetts. That brings out the flowers. And my camera. These flowers photos have slightly better metadata than previous ones because I’ve spent a few days tinkering with jpegRDF.

A Week of Random Thoughtshttp://norman.walsh.name/2004/04/27/random2004-04-28T01:24:00Z2010-10-08T17:57:42.118639ZConferencesCosmologyEmailHumorPhotographyRDFTechnology

A bunch of things crossed my desk last week. In the interest of publishing them before they’re totally irrelevant, here they are.

Not in RDFhttp://norman.walsh.name/2004/04/02/notinrdf2004-04-02T11:03:00Z2010-10-08T17:57:01.740103ZRDF

There isn’t really a simple “not” operator in RDF. Nevertheless, it’s useful, particularly for establishing default values. So what can we do?

Some essays are about specific places. It seemed unfortunate that there was no way to find an essay on that basis. Now you can.

Metadata Wins Again!http://norman.walsh.name/2003/08/21/metadata2003-08-21T12:00:00Z2010-10-08T17:50:13.252497ZRDFSelfReference

Explicitly making use of metadata to drive the production of this website has been a total win several times.

RDF Twighttp://norman.walsh.name/2003/08/19/rdftwig2003-08-19T12:00:00Z2010-10-08T17:50:06.322433ZConferencesRDF

I presented RDF Twig, some work that I did on accessing RDF graphs from XSLT, at Extreme this year.

Vicious Circlehttp://norman.walsh.name/2003/07/29/circle2003-07-29T12:00:00Z2010-10-08T17:49:53.295825ZRDFTAGTheWeb

The TAG is trying to get to last call. There's lots of hard work left to do on our principal deliverable, but hard work isn't a problem. Intractable issues, those are a problem. The question is, how intractable is httpRange-14?

http://..., is that you?http://norman.walsh.name/2003/06/06/karma2003-06-06T12:00:00Z2010-10-08T17:48:05.109375ZRDFTAGTheWeb

Assigning URIs to people, and perhaps to any physical resource, has consequences both social and technical. Socially, I think it's a question of politeness. Am I allowed to make up URIs that identify you? Technically, well, the problems range from straightforward technical challenges, like how do identify when two URIs that are spelled differently point to the same resource and what do you do about it after you have, to the range of http: identifiers.

RSS and RDFhttp://norman.walsh.name/2003/05/22/rssrdf2003-05-22T12:00:00Z2010-10-08T17:47:29.508451ZRDFRSS

On RSS, RDF, and making the former an instance of the latter.
