ITS Data and Service Sharing: the problem I need ITS data or services available in Brussels. May be some cluster projects can help me? Andrea Detti, andrea.detti@uniroma2.it, netgroup.uniroma2.it/people/faculties/andrea-detti/ 2
ITS Data and Service Sharing: the solution Data and Services provided by projects of the cluster Federated Spatial Database for discovery ICN based Andrea Detti, andrea.detti@uniroma2.it
ITS Data and Service Sharing: consumer how to Spatial Query Metadata describing data and services in selected area Direct connection with data and services Andrea Detti, andrea.detti@uniroma2.it, netgroup.uniroma2.it/people/faculties/andrea-detti/ 4
ITS Data and Service Sharing: consumer how to http://bonvoyage2020.eu/travelcentricservices/ Andrea Detti, andrea.detti@uniroma2.it, netgroup.uniroma2.it/people/faculties/andrea-detti/ 5
ITS Data and Service Sharing: producer how to Data and Services GEOJSON Spatial Objects Federated Spatial Database for discovery Data Metadata Extraction Geometry (point, multipoint, line, polygon, etc.) Services Property (URL, king of service, etc.) DATA URL 6 Andrea Detti, andrea.detti@uniroma2.it

OpenGeoBase Distributed/Federated Spatial Database based on Information Centric Networking (ICN) technology Database Engines (modified NDN repo) Range Query Certificate Repo Front-end Library (JNDN running in SPRING App Server) App HTTPs or Local Interface ICN NFD,NLSR Cloud or Virtual Private Network (VPN) 9
State of art: face to face OGB Existing noSQL DB (e.g. MongoDB) Federated deployment Distributed deployment Many administrators responsible of their data partition Geographical sharding Single administrator responsible for all Hash sharding DB engines associated to different geo partition DB engines associated to different hash partition A DB engine can be dedicated to store all data of a country Query routing A DB engine can not be dedicated to store data of a country Query flooding Queries are sent only to relevant DBs Data-centric security Queries sent to all DBs Table-centric security Per-data user right Per-table user right Data owners are responsible for data validity Directive 2010/40/EU compliant Administrator is responsible for data validity ?

Programming: Login import com.bonvoyage.ogb.client.*; String uid = test";// user id String tid = test";// tenant id String pwd = test";// password String cid = "GTFS";// collection id String serverURL = "https://160.80.103.207:443"; String token; OgbClient ogbTestClient = new OgbClient(serverURL); // LOGIN token=ogbTestClient.login(uid, tid, pwd); Andrea Detti, andrea.detti@uniroma2.it, http://netgroup.uniroma2.it/Andrea_Detti 11
Programming: Insert a GeoJSON Point // INSERTION OF POINT OBJECT // point coordinates (lon,lat) double [] coordinates = {0.1, 0.1}; // point properties HashMap<String,String> prop = new HashMap<String,String>(); prop.put( train-name", ICE 373"); prop.put( train-speed", 170 km/h"); // db insertion, response is the object identifier (oid) String oid = ogbTestClient.addPoint(token,cid, prop, coordinates); Andrea Detti, andrea.detti@uniroma2.it, http://netgroup.uniroma2.it/Andrea_Detti 12
Programming: RangeQuery // RANGE QUERY, response is a JSON Array of GeoJSON objects double sw_lat=0.0; double sw_lon=0.0; double size = 0.5; String response = ogbTestClient.rangeQuery(token, cid, sw_lat, sw_lon, size); Andrea Detti, andrea.detti@uniroma2.it, http://netgroup.uniroma2.it/Andrea_Detti 13
