WebSocket connection falls after a while if no data is transmitted.
To prevent this we should:
- increase the timeout
- create a keep alive message that is periodically streamed by triplewave
extends profiling functions with the following
step
linear
gaussian
poissonian
I get some problems with the 'let' statements, is it maybe because of node version?
Using 4.2.6

Hi,
Wikimedia is planning to decommission the socket.io based RCStream in July this year.
A new service called EventStreams is available in its place.
While implementing an alternative version of the SparqlDataGen I noticed that:
I suggest to:
Context should be configurable from either the properties file or the register endpoint
make the /start endpoint able to receive a parameter pointing to a stream URI
"path" parameter in configuration files is not evaluated in
sgraph URL, which results as "http://hostname:port/sgraph"
instead of "http://hostname:port//sgraph"
In case of updatable stores for rdf streams,
it makes senso to have a DataGen that periodically query the
source considering new data to stream out.
Currently, when delay mode is set,
a listener is waiting for connection but, since the execution pipeline is undefined,
it cannot be used.
At the moment, only start.sh works with triplewave 2.0

Hi,
What are the requirements to get the generated RDF outputed via a websocket? Is an Apache or Nginx required for this?
Suppose I want to transform this JSON:
{
"id": 0,
"user": {"name": "Joe"}
}
How can I use the name
of the user
in the mappings? Is something like ... rr:column "user.name"
possible?
On OSX 10.10.x and with node v6.3.0 these errors may occur during the installation of TripleWave:
node-icu-charset-detector
you could see ../node-icu-charset-detector.cpp:5:10: fatal error: 'unicode/ucsdet.h' file not found (tested on OSX 10.10), see herenode-iconv
you could see ../node_modules/nan/nan.h:601:20: error: no type named 'GCPrologueCallback' in 'v8::Isolate'(tested on 10.10), please ignore..Both errors do NOT block the installation of TripleWave and do NOT impact the execution in any way.
Probably we need to clean up the depedencies.
