I wasn't sure if you meant you wanted to access a store you created locally with EF via REST (but still using EF) or if you meant you wanted to use SPARQL or some of our direct RDF APIs on a store you created with EF. The answer in both cases is yes, more detail
on each below.
If you want to access a store that you created with an embedded connection to a local directory over REST then yes you just need to change the connection string (you will of course need to make sure that the store is accessible to the REST server you are connecting
to). However, one word of warning - the BrightstarDB server will (typically) use an embedded connection to access the store - this means that it has control over the files and you should not try to access the store via an embedded connection from any other
process - so once the store is under the control of the server, you should always use a REST connection to access the store via the server.
If you want to actually use SPARQL queries or our direct RDF API to query/update a store created with EF then you can use the
connection string, just change the client you use, so instead of something like:
var context = new MyEntityContext(connectionString);
var client = BrightstarService.GetClient(connectionString);
You will have to include the store name in calls you make to the RDF API, but you can read that from the connection string directly by parsing it with the ConnectionString class and retrieving the StoreName property.
Hope this helps!
