Manual Setup

Manual setup

Manually setting up the framework requires Apache Maven. So start of by getting Maven over here if you haven't already done so. Next, clone the git repository to a destination of your choice.

mkdir ~/dwerft_lpdc
git clone https://github.com/yovisto/dwerft.git ~/dwerft_lpdc

Since there is a bug within rml you have to checkout the rml repository and fix one line.

git clone --recursive https://github.com/RMLio/RML-Mapper.git
git submodule update --init --recursive 
nano  RML-LogicalSourceHandler/src/main/java/be/ugent/mmlab/rml/logicalsourcehandler/termmap/concrete/XPathTermMapProcessor.java
Change:
import java.io.StringBufferInputStream;
StringBufferInputStream input = new StringBufferInputStream(node.toXML().toString());
To:
import java.io.ByteArrayInputStream;
ByteArrayInputStream input = new ByteArrayInputStream(node.toXML().getBytes("UTF-8"));

Lastly provide rml with mvn clean install. Instead of using the string ´UTF-8´ you can also use the Java charset for utf8.

Install TailR:

git clone https://github.com/SemanticMultimedia/tlr-java-api.git
cd tlr-java-api
mvn clean install -DskipTests

If you plan on using an operation which utilizes the Preproducer API, make sure to provide valid credentials. Simply copy the template we provide to the tools directory, and with an editor of your choice add your credentials. Adjust other settings to your needs.

cd ~/dwerft_lpdc/tools
cp src/main/resources/DwerftConfig.properties .
vim DwerftConfig.properties

Irrespective of whether you added credentials or not, you can now execute the lpdc project by running the run script provided. The various arguments available are listed in the next section.

./run.sh <your_arguments>

The [Arguments](Command Line Arguments) have their own wiki page.
