#rdfcli
rdfcli is a command-line Linked Data browser. It allows to visit RDF resources, see their links and follow them across different datasets. The user interface is based on a stateful command line, much like a shell to browse a file system.
It is similar in functionality to other RDF browsers like Disco or Tabulator, but limited to the basic features. When a resource is visited, the URI is dereferenced and the returned triples are loaded to the local graph. The user can then explore the outoing and incoming predicates of the current resource, and navigate to their objects or subjects.
rdfcli uses the Python rdflib library to handle RDF data.
