Coding challenge for DorsaVI

Andrew Matthews

This page contains some of the public things I have been working on. I spend a lot of my spare time (such as it is...) messing about with:

• DSLs and Programming languages
• Labour saving utilities for Fish shell
• Semantic Web Utilities
• Experiments in AI/Comp Sci

Ask me about Semantic Web and Knowledge Graphs to find out how they can help your project. Alternatively, check out some of my recent blog posts over on my blog Industrial Inference

DSLs and language tools

• ActorSrcGen Source Generator for C# Actor Model
• The Fifth Programming Language (site)
• Coco/R compiler generator for Docker.
• A modelling language to describe architectures

Semantic Web and Knowledge Graphs

• Prototype Storage Engine for a Triple Store
• A series of posts on Working with Knowledge Graphs
• An inference engine using SPARQL for RDFS and OWL2
• A CLI app to apply SPARQL migrations to a remote RDF Graph
• A LINQ Query Provider for RDF using SPARQL
• OWL 2 Turtle syntax VS Code snippets

Fish Shell plugins and utilities

• A skeleton plugin for fisher Fish Shell plugin manager.
