openDataWrapper

Generic wrapper converting data sources from data.paysdelaloire.fr into RDF (N3 and RDF-XML). It uses API call. Data sources are XML files. Also uses Apache Maven

Quick Start

1. Requirement :

   • JAVA 1.7

   • Maven : 2.2

     • Eclipse with maven and git plugins installed

2. Start

• git clone https://github.com/hala54/openDataWrapper
• cd openDataWrapper/
• mvn eclipse:eclipse
• mvn install:install-file -DgroupId=de.fuberlin.wiwiss.silk -DartifactId=silk -Dversion=2.5 -Dpackaging=jar -Dfile=lib/silk/silk.jar (add to repo maven local lib silk lib/silk/silk.jar) (More about silk in http://wifo5-03.informatik.uni-mannheim.de/bizer/silk/)
• Open Eclipse, Import the project (import -> General -> existing projects into workspace)
• run Principale.java from Eclipse

3. Data (For non-XML-friendly users)

   Create a file called import.odw into openDataWrapper folder. You can add data from data.paysdelaloire.fr API. Write into the import.odw file the name of your new data, =, and 4 informations separated by ';' : mydata = api_url;api_url_description;title;publisher Select add new sources in the main menu.

   If you are more a more XML friendly, you can add new dataSources directly writing dataSources.xml (more documentation in document.pdf)

4. Convert data

   Select the convert data menu and check the result. The converted files should be in output/ folder.

5. Exporting your data

   Select the Sparql management menu and select the import option. Your dataset will be stored in .openDataWrapper folder. Run fuseki from the menu if you want to expose your data

6. Running SPARQL requests on your DataSets

   Write requests on src/main/resources/queries (1 request per file). Run Principale.java, then follow the instructions through running queries. Before running a query, you shall load a dataset.

7. Linking datasets

   Run Principale.java, then follow the instructions through linking datasets. Select datasets to link, separating datasets numbers by a ';'. Result into src/main/resources/output/linkedData folder

8. Making RDFS inferences

   Write you dataset schema into src/main/resources/input/rdfsSchema. Then run Principale.java and follow the instructions through making RDFS inferences over selected (linked)datasets in relationship with the written schema.

9. Making OWL inferences

   Write you dataset schema into src/main/resources/input/owlSchema. Then run Principale.java and follow the instructions through making OWL inferences over selected (linked)datasets in relationship with the written schema.
