We are happy to let you know that we have released Walder! Walder offers an easy way to set up a website or Web API on top of decentralized knowledge graphs, which can be hosted via Solid PODs, SPARQL endpoints, Triple Pattern Fragments interfaces, RDF files, and so on. Using content negotiation, Walder makes the data in these knowledge graphs available to clients via HTML, RDF, and JSON-LD. You define in a configuration file which data Walder uses and how it processes this data.
Our own website uses Walder. Especially, our team page shows the power of decentralized knowledge graphs as it queries different Solid PODs, websites with JSON-LD and plain RDF files to collect the content that is displayed.
Wanna try it out? Check out the examples in the repository or follow our tutorial that guides you through the creation of your first website using Walder.
