Semantic Mapping Service

The TOOP Semantic Mapping Service is a specific instantiation of the TNO Plasido platform for ontology-based integration of linked data sources.

It contains 2 specific containers:

• one for the Apache Jena Fuseki triplestore that contains the TOOP Common Semantic Model and its mappings to national data models, and
• one for the GRLC component that provides a REST-API with various GET operations that are translated to SPARQL queries on the Fuseki triplestore

How to start the TOOP Semantic Mapping Service

Execute the following steps:

• Make sure you have Docker, Docker Compose and Git installed.

• Git clone this Semantic Mapping Serivce repository to your computer.

• Open a shell and navigate to your git clone of the SMS.

• Copy the .env.default file to a .env file in the root directory of this local repository

• Add a Github API access token to it as indicated in the last lines of the .env.default file, which looks like: env_github_access_token=<hexadecimal Github API token that has to be generated at Github>

• If you don't have a Github API access token, you can also contact jack.verhoosel@tno.nl to get one

• Execute the following command: docker-compose build fuseki grlc and then docker-compose up -d fuseki grlc

• The SMS services Fuseki and GRLC will be started automatically, this might take a while (also when the command is already finished, it might still take a while for all the services to be started).

• Now you can access different services of SMS. In the browser open:

  • Apache Jena Fuseki: http://localhost:3030.
  • GRLC: http://localhost:9001.

Note that we assume your docker host is available on localhost (which is the case if you are using Docker for Linux or recent Docker for Windows and Mac) If you want to use a different port number for the GRLC service, you can edit it in the .env file by changing GRLC_PORT=9001 to GRLC_PORT=<your-port>
