Securing SPARQL endpoints

SPARQL endpoints are Web services, and they are capable of more than providing Read-Only access to a back-end graph DBMS.

Though commonly general-purpose, SPARQL endpoints can also be purpose-specific, and their privileges may therefore be limited to specific Create, Read, Update, and/or Delete operations.

The privileges provided by a given Virtuoso SPARQL endpoint may be based simply upon the endpoint's URL, or upon sophisticated rules which associate specific user identities with specific database roles and privileges.

Virtuoso offers three methods for securing SPARQL endpoints:

By default, Virtuoso has several purpose-specific SPARQL endpoints, associated with these authentication methods along the following lines --
