Amazon Neptune now supports “Concise Bounded Description” queries for SPARQL query language
Amazon Neptune version 1.2.0.2 now supports the W3C RDF CBD (Concise Bounded Description) for the SPARQL query language. The Concise Bounded Description of an RDF resource (that is, a node in an RDF graph) is the smallest subgraph of leaf nodes that are not blank (anonymous resource, a node with no URI). A CBD query starts from a node, then recursively traverses the graph beyond blank nodes until it finds a node with an identifier.
