SketchUp MashUp HeadsUp
My recent post, Using Cucumber with SketchUp, discussed one possible way to combine Google SketchUp with other packages. However, there are lots of other possible mash-ups. This entry discusses some of these; other suggestions are welcome... ...Continue reading "SketchUp MashUp HeadsUp"

Visualizing RDF and OWL data models
The data models for Resource Description Framework (RDF) and Web Ontology Language (OWL) can be a bit difficult to understand, even at the simplest level. Here are some visualizations (and explanations) I've found useful: I'd be delighted to hear about other ways of thinking about this. All comments and/or corrections are welcome... ...Continue reading "Visualizing RDF and OWL data models"

Semantic Web Installfest - meeting notes
I recently organized an Installfest for the San Francisco Semantic Web Meetup. It was held at PariSoMa, a co-working venue in SoMa (South of Market Street in San Francisco).

but the primary one was to bring together a group of SemWeb enthusiasts
who want to learn about the technology, try things out, discuss alternatives, etc.
I love hearing about successful Semantic Web projects,
but I also want to "get my hands dirty" using the tools.

Turtle (Terse RDF Triple Language) is a great improvement, but it's still a bit verbose for my tastes. SPARQL, being largely modeled after Turtle, shares many of its limitations. ...Continue reading "Improving the Conciseness of Turtle and SPARQL"

Safety Nets for OWLs
I've been programming for several decades, but I'm relatively new to ontology development in general and OWL in particular. So, I'm certainly not an expert on the range of work in this area. However, I think I see some areas where programming best practices and tools could provide useful "safety nets" for OWL-based ontology developers. ...Continue reading "Safety Nets for OWLs"
