Storage Providers

This area of the User Guide covers the available IStorageProvider and IAsyncStorageProvider implementations. Each provider has its own page which details provider specific behaviour and any special functionality available for that provider.

You should read the Triple Store Integration page for an overview of how to use the Storage API.

The available providers are as follows:

Provider	Description
Allegro Graph	AllegroGraph 3.x and 4.x
Blazegraph	Blazegraph
Dataset Files	Read-only view over a NQuads/TriG/TriX file
4store	4store
Fuseki	Apache Jena Fuseki, access any Jena based store via Fuseki
In-Memory	In-Memory store
Sesame	Any Sesame based store is supported e.g. Sesame, OWLIM, BigData
SPARQL Query Endpoints	Any SPARQL Query endpoint
SPARQL Query and Update Endpoints	Any store providing both a query and update endpoint
SPARQL Graph Store Protocol	Any SPARQL Graph Store Protocol endpoint
Stardog	Stardog

[!INFO] dotNetRDF 3.0 has dropped support for connecting to a Virtuoso server through the Virtuoso client library as this library requires a dependency on .NET Framework and cannot be used on a modern .NET stack. It is still possible to connect to a Virtuoso server via its SPARQL query, update and graph store protocol endpoints using the generic SPARQL connectors provided by dotNetRDF.

There are also some useful wrappers available:

Wrapper	Description
ReadOnlyConnector	Make any other provider read-only
QueryableReadOnlyConnector	Make any queryable provider read-only
