Explorer 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.

Walder est écrit en NodeJS, il serait intéressant de voir s'il y a des interconnexions possibles avec SemApps.

Voir ce tutorial: https://pieterheyvaert.com/blog/2020/08/31/getting-started-with-walder/

Read the linked Walder tutorial and compare its Solid POD, SPARQL, Triple Pattern Fragments, RDF, HTML, and JSON-LD interfaces with SemApps. The issue names no files or tests and does not define a concrete implementation boundary; done would require an agreed integration direction.
