charnik@211 4 Introduction
charnik@211 5 ============
charnik@211 6 Strabon is a fully implemented semantic geospatial database system that can be
charnik@211 7 used to store linked geospatial data expressed in RDF and query them using an
charnik@211 8 extension of SPARQL. Strabon supports spatial selections, spatial joins, a rich
charnik@211 9 set of spatial functions similar to those offered by geospatial relational
charnik@211 10 database systems, support for multiple Coordinate Reference Systems and widely
charnik@211 11 used serializations for geometric objects such as WKT and GML. Strabon is built
charnik@211 12 on top of the well-known RDF store Sesame and extends Sesame’s components to be
charnik@211 13 able to manage thematic and spatial data that are stored in PostGIS.
charnik@211 14
charnik@211 15 The development of Strabon started in the context of European FP7 project
charnik@211 16 SemsorGrid4Env (Semantic Sensor Grids for Rapid Application Development for
charnik@211 17 Environmental Management) [http://www.semsorgrid4env.eu/]. Starting September
charnik@211 18 2011, Strabon is being utilized and extended with new functionalities in the
charnik@211 19 FP7 project TELEIOS (Virtual Observatory Infrastructure for Earth Observation
charnik@211 20 Data) [http://www.earthobservatory.eu/] which our group leads.
charnik@211 21
charnik@211 22 The query language of Strabon is called stSPARQL. stSPARQL can be used to query
charnik@211 23 data represented in an extension of RDF called stRDF. stRDF and stSPARQL have
charnik@211 24 been designed for representing and querying geospatial data that changes over
charnik@211 25 time (e.g., the growth of a city over the years due to new developments).
charnik@211 26
charnik@211 27 Currently, only the geospatial features of stSPARQL have been implemented fully.
charnik@211 28 The temporal features are the subject of current work.

charnik@211 41 Getting Started
charnik@211 42 ===============
charnik@211 43 To get started with Strabon please have a look at the tutorial for the stRDF
charnik@211 44 data model and stSPARQL query language, the User Guide, and the Developer Guide.

charnik@211 49 User Guide
charnik@211 50 ~~~~~~~~~~
charnik@211 51 Assuming that you are familiar with Maven, the following steps need to be
charnik@211 52 followed in order to use Strabon using Eclipse:
charnik@211 53
charnik@211 54 1. Install PostgreSQL from http://www.postgresql.org/download/. At the time of
charnik@211 55 this writing the latest PostgreSQL version is 9.1.
charnik@211 56 2. Install PostGIS from http://postgis.refractions.net/download/. At the time of
charnik@211 57 this writing we have tested Strabon with PostGIS 1.5.3.
charnik@211 58 3. Install Maven from http://maven.apache.org/download.html. At the time of this
charnik@211 59 writing the latest Maven version is 3.0.4.
charnik@211 60 4. Install Eclipse from http://www.eclipse.org/downloads/. At the time of this
charnik@211 61 writing the latest Eclipse version is 3.7.2.
charnik@211 62 5. Install the m2e plugin for Eclipse from http://www.eclipse.org/m2e/.
charnik@211 63 6. Install the MercurialEclipse plugin for Eclipse from
charnik@211 64 http://javaforge.com/project/HGE .
charnik@211 65 7. From Eclipse, go to File --> Import --> Mercurial --> Clone Existing
charnik@211 66 Mercurial Repository --> Next. In the URL textarea paste the following
charnik@211 67 URL: http://hg.strabon.di.uoa.gr/StrabonUser and then press Next --> Next -->
charnik@211 68 Finish. If you used the default settings, you should have a new project named
charnik@211 69 StrabonMain. Right click on the project and select Configure --> Convert to
charnik@211 70 Maven project. Eclipse will enable Maven dependency management for the
charnik@211 71 project, download any dependencies and build the project.
