Petri Nets are extremely powerful and expressive, but they are not as widely used as state machines. That's a pity, they allow us to solve problems beyond the reach of state machines. This post is the first in a mini-series on software development with Petri Nets. All of the code for a full feature-complete Petri Net library is available online at on GitHub. You're welcome to take a copy, play with it and use it in your own projects[ READ MORE ]
The semantic web is a GOOD THING by definition – anything that enables us to create smarter software without also having to create Byzantine application software must be a step in the right direction. The problem is – many people have trouble translating the generic term “smarter” into a concrete idea of what they would [ READ MORE ]
Andrew Cantos raised some interesting philosophical points in reply to my partially tongue in cheek post The Great Domain Model Debate – Solved the other day. As ever, my short reply turned into a blog post and this is it. Andrew’s point was that there is a metaphorical link between objects in a domain model [ READ MORE ]
I thought it was worth describing this configuration solution, since it was so neat, and easy, and had all of the benefits of text based configuration and strongly typed inline configuration[ READ MORE ]
I was wondering the other day whether LINQ could be used with NMock easily. One problem with testing code that has not been written to work with unit tests is that if you test business logic, you often end up making multiple round-trips to the database for each test run. With a very large test [ READ MORE ]
OWL defines two types of property: DatatypeProperty and ObjectProperty. An object property links instances from two Classes, just like a reference in .NET between two objects. In OWL you define it like this: <owl:ObjectProperty rdf:ID=”isOnAlbum”> <rdfs:domain rdf:resource=”#Track”/> <rdfs:range rdf:resource=”#Album”/> </owl:ObjectProperty> A DatatypeProperty is similar to a .NET property that stores some kind of primitive [ READ MORE ]
Darren Neimke posted some interesting thoughts today about the way developers lose their drive on a project, and how it’s reflected in SCRUM meetings. He thought that it might be due to the SCRUM meetings themselves. Daniel Crowley-Wilson has another idea – the developers are just bored. Developers relish challenges and opportunities to do new [ READ MORE ]
When I started implementing the SPARQL support in LINQ to RDF, I decided that I needed to implement as much of the standard query operators as possible. SPARQL is a very rich query language that bears a passing syntactical resemblance to SQL. It didn’t seem unreasonable to expect most of the operators of LINQ to [ READ MORE ]
I’ve been given a week by work to try to make some progress on the LINQ to RDF query provider, and I’m glad to say that the query generation phase is now pretty much complete for SPARQL. It’s amazing what a difference a full day can make to your progress, compared to trying to get [ READ MORE ]
Progress with the LINQ to RDF Query Provider is continuing apace. I have been pretty tightly focused for the last few days, so I haven’t ad time to post an update. I’ve lately been working on a SPARQL query, which will allow me a much richer palette to play with. Here’s the current version of [ READ MORE ]
