2. About Me Software Engineer at Cray Writing up my PhD Thesis in spare time – “Link Integrity for the Semantic Web” Run the dotNetRDF Project – Started January 2009 – Latest Releases 0.5.1 Beta (APIs) 0.4.0 Beta (Toolkit) 12/6/2011http://www.dotnetrdf.org2

3. My Life as a Semantic Web Developer Constantly working with different data sources, formats, vocabularies etc. Was frustrated by limited tooling around conversion, query prototyping and editing – Especially the *nix/Java bias of available tooling Seemed pointless to keep writing tiny Java/.Net programs to do everyday tasks 12/6/2011http://www.dotnetrdf.org3

4. Tools All free to use/open source – All of which I’ve used at one stage or another – Some of which I use on a daily basis Demos – Going to demo my favourite tool in each category – Slides have links to other useful tools and will be available on SlideShare 12/6/2011http://www.dotnetrdf.org4
