  title: Stardog HTTP Checkpoints Graph Store Protocol API
  description: "# Overview\nStardog supports the standard SPARQL Protocol HTTP bindings, as well as additional functionality via HTTP.\nStardog also supports SPARQL 1.1’s Service Description format. See the [spec](https://www.w3.org/TR/sparql11-service-description/) if you want details.\n### Generating URLs\nIf you are running the HTTP server at\n\n ```http://localhost:12345```\n\nTo form the URI of a particular Stardog Database, the Database Short Name is the first URL path segment appended to the deployment URI. For example, for the Database called `cytwombly`, deployed in the above example HTTP server, the Database Network Name might be\n\n```http://localhost:12345/cytwombly```\n\nAll the resources related to this database are identified by URL path segments relative to the Database Network Name; hence:\n\n```http://localhost:12345/cytwombly/size```\n# Error Codes\nHere are explanations of what the various error codes mean:\n\nError Code | Category | Meaning\n-----------|----------|---------\n000012 | GENERIC |UNKNOWN\n000IA2 | GENERIC |ILLEGAL_ARGUMENT\n000SD4 | GENERIC |SHUTTING_DOWN\n00PCE2 | GENERIC |PROCESS_CANCELLED\n00PE2 | GENERIC |PROCESS_EXISTS\n00PNE2 | GENERIC |PROCESS_NOT_FOUND\n00UOE2 | GENERIC |UNSUPPORTED_OPERATION\n0D0012 | DATABASE |UNKNOWN_DATABASE_EXCEPTION\n0D0CE3 | DATABASE |DATABASE_CONSISTENCY_EXCEPTION\n0D0DC2 | DATABASE |DATABASE_CONFLICT\n0D0DE2 | DATABASE |DATABASE_EXISTS\n0D0DU2 | DATABASE |DATABASE_UNKNOWN\n0D0TU2 | DATABASE |TRANSACTION_UNKNOWN\n0DICC2 | DATABASE |INVALID_CONFIGURATION\n0DIDN2 | DATABASE |INVALID_DATABASE_NAME\n0DIDS2 | DATABASE |INVALID_DATABASE_STATE\nCLNIC3 | CLUSTER_ERROR |NOT_IN_CLUSTER\nCLOEF3 | CLUSTER_ERROR |EXPEL_FAILED\nHS0012 | HTTP |UNKNOWN_CONNECTION_EXCEPTION\nHSJSE2 | HTTP |JSON_SYNTAX_EXCEPTION\nHSJSO2 | HTTP |JSON_EXCEPTION\nHSSSL3 | HTTP |SSL_EXCEPTION\nQE0012 | QUERY_EXECUTION |UNKNOWN_QUERY_EXCEPTION\nQE0FE2 | QUERY_EXECUTION |FUNCTION_EXISTS\nQE0PE2 | QUERY_EXECUTION |PARSE_EXCEPTION\nQE0QE2 | QUERY_EXECUTION |QUERY_EXISTS\nQECTP2 | QUERY_EXECUTION |CANNOT_TRANSLATE_PLAN\nQEFNF2 | QUERY_EXECUTION |FUNCTION_NOT_FOUND\nQEIQT2 | QUERY_EXECUTION |INVALID_QUERY_TYPE\nQEIVR2 | QUERY_EXECUTION |INVALID_RDF\nQEMAQ2 | QUERY_EXECUTION |MALFORMED_QUERY\nQEONS2 | QUERY_EXECUTION |OPERATION_NOT_SUPPORTED\nQEQNF2 | QUERY_EXECUTION |QUERY_NOT_FOUND\nQEQOE2 | QUERY_EXECUTION |OPERATOR_EXCEPTION\nQEQPE2 | QUERY_EXECUTION |QUERY_PARSE_EXCEPTION\nQEWCE2 | QUERY_EXECUTION |WRITE_CONFLICT_EXCEPTION\nSE0012 | SECURITY |UNKNOWN_SECURITY_EXCEPTION\nSE0IP2 | SECURITY |ILLEGAL_PASSWORD\nSE0RE2 | SECURITY |SECURITY_RESOURCE_EXISTS\nSEAEE2 | SECURITY |AUTHENTICATION_EXCEPTION\nSEAOE2 | SECURITY |AUTHORIZATION_EXCEPTION\nSEIPT2 | SECURITY |INCORRECT_PRINCIPAL_TRANSACTION\nSERIU2 | SECURITY |SECURITY_RESOURCE_IN_USE\nSERNF2 | SECURITY |SECURITY_RESOURCE_NOT_FOUND\nSERNI2 | SECURITY |SECURITY_RESOURCE_NAME_INVALID\nSERTI2 | SECURITY |SECURITY_RESOURCE_TYPE_INVALID\nZK0013 | ZOOKEEPER_ERROR |ZOOKEEPER_UNKNOWN_EXCEPTION\nZK00U3 | ZOOKEEPER_ERROR |UNIMPLEMENTED\nZK0AE3 | ZOOKEEPER_ERROR |API_ERROR\nZK0AF3 | ZOOKEEPER_ERROR |AUTH_FAILED\nZK0BV3 | ZOOKEEPER_ERROR |BAD_VERSION\nZK0CE3 | ZOOKEEPER_ERROR |NO_CHILDREN_FOR_EPHEMERAL\nZK0CL3 | ZOOKEEPER_ERROR |CONNECTION_LOSS\nZK0CR3 | ZOOKEEPER_ERROR |ZOOKEEPER_CONNECTION_REFUSED\nZK0DI3 | ZOOKEEPER_ERROR |DATA_INCONSISTENCY\nZK0IA3 | ZOOKEEPER_ERROR |BAD_ARGUMENTS\nZK0ME3 | ZOOKEEPER_ERROR |MARSHALLING_ERROR\nZK0NA3 | ZOOKEEPER_ERROR |NO_AUTH\nZK0NE3 | ZOOKEEPER_ERROR |NODE_EXISTS\nZK0NN3 | ZOOKEEPER_ERROR |NO_NODE\nZK0OT3 | ZOOKEEPER_ERROR |OPERATION_TIMEOUT\nZK0RI3 | ZOOKEEPER_ERROR |RUNTIME_INCONSISTENCY\nZK0SE3 | ZOOKEEPER_ERROR |SYSTEM_ERROR\nZK0SM3 | ZOOKEEPER_ERROR |SESSION_MOVED\nZKEXS3 | ZOOKEEPER_ERROR |SESSION_EXPIRED\nZKIAL3 | ZOOKEEPER_ERROR |INVALIDACL\nZKICB3 | ZOOKEEPER_ERROR |INVALID_CALLBACK\nZKNEY3 | ZOOKEEPER_ERROR |NOT_EMPTY\nZKNRO3 | ZOOKEEPER_ERROR |NOT_READONLY\n"
