D2.5Proof-of-Concept

Evaluation for Modelling Time and Space

Slide 2 of x11/02/11

Motivation (I)

• Increasing amount of geospatial data being published as Linked Data• LinkedGeoData• OrdnanceSurvey, IGN Spain, IGN France, etc.• European Environmental Agency• ...

• Different vocabularies (heterogeneity)• GeoSPARQL• NeoGeo• W3CBasic GeoVocabulary• the ISAProgramme Core Location Vocabulary• schema.org’s coordinates and polygons

Slide 3 of x

Motivation (II)

• Besides, geospatial data can be combined with statistical data, sensor data, etc., which also provide a temporal perspective

• Again, different (standardised) vocabularies• W3C RDF Data Cube• Semantic Sensor Network Ontology

Deliverable objective

• Implement and describe a prototype tool that makes use of data according to a combination of these vocabularies• Map4RDF-iOS • https

• Developed in parallel to Map4RDF• http://map4rdf.oeg-upm.net/

• Two demos presented• ISWC2013 Semantic Sensor Network

workshop (SSN2013). Sydney, October 2013• W3C/OGC Linking Geospatial Data Workshop.

Map4RDF-iOS main features

– iOS mobile devices (v5 to v7) with optimised memory management

– Multiple map servers (OSM, Google, Apple, Nokia)

– Data– Statistical data modelled as W3C's DataCube– Multiple geospatial data models: W3C Geo XG,

GeoLinkedData, and WKT/GeoSPARQL

– Clustering of data points– Customizable by end users, e.g. definition

of SPARQL endpoints and queries

Map4RDF-iOS limitations

– Single platform (iOS)– Working with Titanium Appcelerator to provide

a combination of native + HTML5 widgets

– Only support for (non-authenticated) SPARQL endpoints.

– One map server and one endpoint at a time.

– No data edition– Connectivity module to save & share

configurations, snapshots, and LGD datasets
