report of Saltlux on comparing plotting of AMA and ?LinkedGeoData for a small area of Milan
- report on D5.3.2 and pending requests to WP5
- AOB
Discussion minutes:
- report on communication from CEFRIEL to EPMB on Stefano Bertolo’s requests:
- Emanuele sent and email to the EPMB
- Georgina answered that WP5 meeting in Amstredam will take WP6 requests into consideration
Naso reported on availability of machines in ?OntoText premises and asked for configuration details
Florian proposed to discuss on current code for reading the triples in ?SimpleFileReader
// Access RDF graph exposed according linked data principles
RdfGraph g = df.createRemoteRdfGraph(new URIImpl(uriName));
RdfStoreConnection con = df.createRdfStoreConnection();
// Transfer all remote data
CloseableIterator<Statement> iter = g.getStatements();
Set<Statement> statements = new HashSet<Statement>();
while (iter.hasNext()) {
Statement s = iter.next();
statements.add(con.addStatement(s.getSubject(), s.getPredicate(), s.getObject(), (URI)s.getContext()));
}
iter.close();
// Create a RdfGraph passed by value
URI graphName = new URIImpl(uriName);
RdfGraph graph = df.createRdfGraph(statements, graphName);
- apparently we load the graph twice, on in memory and one in storage
- why?
- can we pass the data in memory to next plug-in?
- if it is for caching,
- how can we know that the graph is already in the repository?
- how can we delete the graph
- IDEA: plug-ins that run continuously and load new data on regular basis
- report of Siemens analysis of new Milan map
- Florian extracted from the shapefiles the links, the nodes, and the sensors. He also connected to the sensor to the links
- discussion about categories: the data contains 20 categories, Florian reduced them to the orginal 4 categories
- task(Florian) redo the exporting with the orginal categories as well
- discussion about Additional information
- task(Florian) add street names and length at least
- task(all) tell Florian which other feature we may want to export
- discussion about reference system in the Gauss-Boaga
- task(Daniele in January) conversion from Gauss-Boaga to WGS-84
- Florian also reported that
- in parallel he wrote a plug-in that exposes the traffic data in RDF to LarKC
- another plug-in will be written for providing the path finding WF with predicted average speed of each link
Task(Emanuele) ask WP5 to explain how configure plug-in (e.g. ?SimpleFileReader) (Florian in CC).
- Discussion about ontology
- Task(Florian) describe the extra classes and properties for sensors
report of Saltlux on comparing plotting of AMA and ?LinkedGeoData for a small area of Milan
- AOB
- Task(Emanuele) prepare an email with all the request from WP6 to WP5
