With Semiodesk Trinity, we offer a feature-rich development platform to create Semantic Web powered applications in C#.Net/Mono. If you are looking for an object mapping API for graph databases or just want a simple way to consume linked open data from your applications, Trinity can deliver.
Because we want to get as many people as possible interested in Semantic Web, we have made sure it is dead simple to use. Furthermore, to make it available to anyone, we have released it under the MIT license. This means you can use it for free, even for commercial projects.
For a detailed overview what Trinity can offer you, please visit our product page. If you just want to try it out, just head over to our tutorial and follow the instructions. For arising problems or bugs, please use our issue tracker. Please contact us under firstname.lastname@example.org if you have any further questions.
