The Reconciliation Server is a mapping server that allows you to create associations that map concepts of a concept class into Workspace Models, Remote Sources, and URI/URLs. For more information, refer to Concepts Service Documentation.
If required, install the Reconciliation Server by executing the following command:
yum install Semaphore-ConceptsServer-<version>.noarch.rpm
The installer will have created a service semaphore-concepts. After installing, start the service with the following command:
systemctl start semaphore-concepts
If you do not want to use the service (e.g. you are using a docker container), then set your working directory to:
/opt/semaphore/concepts
Then run the command:
bin/start.sh
The script should set the following environment variable:
SEMAPHORE_LOG_DIR=/var/opt/semaphore/concepts/logs.
Note: After upgrading to a newer version of the Concepts Server, it is recommended to republish your Semaphore models.
