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.

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.
For example, a CBD in a patient 360 healthcare application can be used to describe all the information related to a patient (a node). Here, the CBD query is a way to break the graph into small subgraphs that could be handled as 'objects', to facilitate the retrieval or to transactionally change its content.
To get started with CBD queries, visit the Amazon Neptune SPARQL DESCRIBE documentation. For more information on Amazon Neptune pricing and region availability, refer to the Neptune pricing page and AWS Region Table.
