Hm again a twist: So with the connect timeout no longer present on the
connection itself I have to set it on initialization.
However for this part I was using my own assembler-like setup which sets up
a factory for RDFConnection objects from an RDF document. Back then I didn't
realize that Jena's assembler system is generic so it can create any java
object from RDF.
In my case, this allows for linking RDF benchmark results to the RDF
document with the attributes for the connection setup and used thresholds.
Rather then extending my own system I'd rather integrate with Jena
assemblers.
I think there is not yet an assembler for RDFConnection instances - is there?
So a rought draft would look like
```ttl
#conn.ttl
<#httpClient> a ja:HttpClient ;
ja:connectTimeout 10 . # seconds
<#conn> rdf:type ja:HttpRDFConnection;
ja:destination <http://dbpedia.org/sparql> ;
ja:httpClient <#httpClient> .
```
Followed by
```java
Model model = ModelFactory.load("conn.ttl").getResource("#conn");
RDFConnection conn = RDFConnectionFactory.assemble(model);
```
However, instead of returning only a single connection it may be better to
create a factory for connections:
```java
/** A factory/supplier of RDFConnection instances. Similar to a JDBC
DataSource. */
public interface RDFDataSource
{
RDFConnection getConnection();
}
RDFDataSourceFactory.assemble(...);
```
