%description
    Cayley is a graph inspired by the graph database behind Freebase
    and Google's Knowledge Graph. Its goal is to be a part of the
    developer's toolbox where Linked Data and graph-shaped data
    (semantic webs, social networks, etc) in general are concerned. It
    provides a REST API and a GraphQL query mechanism. It is based on an
    underlying embedded or external database.
