sparql Working with graphs


What is a Named Graph? An internal database document identifier (name) used by a SQL-compliant RDBMS to partition storage of relations represented as RDF sentence/statement graphs. Why are Named Graphs Important? A Named Graph is like a page in a book (the database) that contains a collection of paragraphs (sentence collections). Thus, it provides a powerful mechanism for query scoping that negates the need to scope all database queries to the entire database.
