Remarks

Connection to AllegroGraph is based on their new HTTP Protocol which is an extension of the Sesame 2.0 HTTP Protocol. The specification for the AllegroGraph protocol can be found. here

If you wish to use a Store which is part of the Root Catalog on an AllegroGraph 4.x and higher server you can either use the constructor overloads that omit the catalogID parameter or pass in null as the value for that parameter.
