The BigdataSailFactory class is in the com.bigdata.rdf.sail package. This is the same package as the BigdataSail. However, the BigdataSailFactory class is a client client and needs to be part of the client jar. Therefore it needs to be moved to the appropriate client package. Since this class wraps up the REST API using the openrdf http API, the correct package is com.bigdata.rdf.sail.remote.
1. Move the class to the correct package.
2. Update the online documentation for this class to reflect the correct package.
