charnik@211 2 -----------

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 29
kkyzir@639 30 Given the very close relationship between stSPARQL and GeoSPARQL which is a
kkyzir@639 31 recent OGC standard for an extension of SPARQL for querying geospatial metadata,
kkyzir@639 32 we recently provided support for the Core, Geometry and Geometry Topology
kkyzir@639 33 extension of GeoSPARQL.

charnik@211 48 To get started with Strabon please have a look at the tutorial for the stRDF
charnik@211 49 data model and stSPARQL query language, the User Guide, and the Developer Guide.

kkyzir@800 57 The reference for the spatial and temporal extension functions defined in
kkyzir@800 58 stSPARQL can be found at http://www.strabon.di.uoa.gr/stSPARQL#spatial and

charnik@211 62 User Guide
charnik@211 63 ~~~~~~~~~~
charnik@211 64 Assuming that you are familiar with Maven, the following steps need to be
charnik@211 65 followed in order to use Strabon using Eclipse:
charnik@211 66
charnik@211 67 1. Install PostgreSQL from http://www.postgresql.org/download/. At the time of
charnik@211 68 this writing the latest PostgreSQL version is 9.1.
charnik@211 69 2. Install PostGIS from http://postgis.refractions.net/download/. At the time of
charnik@211 70 this writing we have tested Strabon with PostGIS 1.5.3.
charnik@211 71 3. Install Maven from http://maven.apache.org/download.html. At the time of this
charnik@211 72 writing the latest Maven version is 3.0.4.
charnik@211 73 4. Install Eclipse from http://www.eclipse.org/downloads/. At the time of this
charnik@211 74 writing the latest Eclipse version is 3.7.2.
charnik@211 75 5. Install the m2e plugin for Eclipse from http://www.eclipse.org/m2e/.
charnik@211 76 6. Install the MercurialEclipse plugin for Eclipse from
charnik@211 77 http://javaforge.com/project/HGE .
charnik@211 78 7. From Eclipse, go to File --> Import --> Mercurial --> Clone Existing
charnik@211 79 Mercurial Repository --> Next. In the URL textarea paste the following
charnik@211 80 URL: http://hg.strabon.di.uoa.gr/StrabonUser and then press Next --> Next -->
charnik@211 81 Finish. If you used the default settings, you should have a new project named
charnik@211 82 StrabonMain. Right click on the project and select Configure --> Convert to
charnik@211 83 Maven project. Eclipse will enable Maven dependency management for the
charnik@211 84 project, download any dependencies and build the project.

charnik@211 87 Storing stRDF graphs and evaluating stSPARQL queries
charnik@211 88 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
charnik@211 89 You can see some examples in the classes gr.uoa.di.strabon.example.PostgisExample
charnik@211 90 and gr.uoa.di.strabon.example.PostgisExample2.
charnik@211 91
kkyzir@954 92 Tuning PostgreSQL
kkyzir@954 93 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
kkyzir@954 94 The default settings of Postgres are rather conservative. As a result, parameter
kkyzir@954 95 tuning is neccessary for speeding up Postgres, therefore Strabon. If you are
kkyzir@954 96 using Strabon to compare its performance against your implementation of
kkyzir@954 97 stSPARQL/GeoSPARQL, you are *strongly* encouraged to contact us using the Strabon
kkyzir@954 98 Users mailing list for assistance on tuning Postgres.
kkyzir@954 99
kkyzir@954 100 You can follow the instructions below for tuning a Postgres server running on an
kkyzir@954 101 Ubuntu machine that is dedicated to PostgreSQL and Strabon.

sgian@627 353 Known Issues
sgian@627 354 ============
charnik@846 355 * By default, Tomcat uses ISO-8859-1 character encoding when decoding URLs received
charnik@846 356 from a browser. This can cause problems when encoding is UTF-8, and you are using
charnik@846 357 international characters. In order to fix this, edit conf/server.xml and find the
charnik@846 358 line where the Connector is defined. Add the parameter URIEncoding and set it to
charnik@846 359 UTF-8. For example:
sgian@627 360
charnik@846 361 <Connector port="8080" protocol="HTTP/1.1"
charnik@846 362 connectionTimeout="20000"
charnik@846 363 URIEncoding="UTF-8"
charnik@846 364 redirectPort="8443" />
charnik@846 365
charnik@846 366 * Building and executing any maven goals fails for maven versions <3.0 due to a
charnik@846 367 dependency to the `shade' plugin that is available only for maven version 3.0
charnik@846 368 (http://maven.apache.org/plugins/maven-shade-plugin/). In such systems, you may
charnik@846 369 disable execution of this plugin by setting the environmental variable
charnik@846 370 `shade.skip'. For example, to build Strabon using maven version 2.0 you may
charnik@846 371 execute the following command:
charnik@846 372
charnik@846 373 $ mvn clean package -Dshade.skip

sgian@967 375 * When using MonetDB as a backend, the following source code of MonetDB must be
sgian@967 376 used:
sgian@967 377 https://hg.strabon.di.uoa.gr/MonetDB/
