Welcome to the TripleCheckMate wiki!

TripleCheckMate is a GWT web application for evaluating RDF datasets.

To use TripleCheckMate you need a Java Server (Tomcat, Jetty) and a MySQL database (a standalone H2 database will also be supported).

Installation

1. Import the default database into MySQL: src/main/webapp/db/evaluation.default.sql
2. For the latest war file run $mvn install in the root directory
3. Copy target/TripleCheckMate-Version.war' into the the server's webroot` folder
4. Adjust & Copy src/main/webapp/db/storage.properties.default to webroot/TripleCheckMate/db/storage.properties

Configuration

Go the campaign table in the database and adjust the fields of record with id=1. In the future we plan to support multiple evaluation campaigns.

To support the Google Authentication method go to https://code.google.com/apis/console and create a new project. Set `http://example.com:portNumber/TripleCheckMate/oauthWindow.html' as the redirect URL and adjust the clientID in client/widgets/StartPage.java. In the future we will put this configuration in a property file or the database.

For dereferencing you might want to use a local mirror. For this reason you can replace the resource URIs to the local ones in shared/sparql/ResultItem.java and in client/widgets/EvaluationPage.java for the result header.

We used prefix.cc to import the most common prefixes. If these prefixes are not enough for your project you can adjust the code in shared/sparql/PrefixService.java

Finally, to adjust the front page of your evaluation campaign you should adjust the following files

• src/main/resources/org/aksw/TripleCheckMate/client/widgets/StartPage.ui.xml
• src/main/webapp/TripleCheckMate.html

Contribute

We will happily accept patches (pull requests) that will help us fix existing issues, ease the configuration process or improve the application in any way.
