Directories

• /deployment: Docker Compose setup to bring up a full stack of collector, importer, endpoint and application.

• /doc: Project documentation. Includes a timeline to do list.

• /experimental: Playing around with various components and technologies.

• /src: Implementation source code.

  • /src/uloapi: RDF4J/JVM-based endpoint to the dataset.

  • /src/ulocollect: Collects and imports data from MathHub into a database.

  • /src/ulo-rdf4j: Script for generating ULO.java which contains constants for use with RDF4J.

Configuration for Docker Compose

Configuration of the /deployment Docker Compose setup consists of three port numbers.

• ULOCOMPOSE_DBPORT is the port the GraphDB instance is exposed to.

• ULOCOMPOSE_COLLECTPORT is the port the collector is exposed to.

• ULOCOMPOSE_APPPORT is the port the application is exposed to.

There is no authentication. You will have to add some yourself.

Configuration for Local Installs

The src/ulo-storage-applications web interface listens on 0.0.0.0:7400. If you wish to change this, you can set the environment variables

• ULOAPPS_LISTEN_HOST for the host, e.g. localhost or some IP address.

• ULOAPPS_LISTEN_PORT for the port number, e.g. 7400 or 1234.

ulo-storage-applications needs a reachable GraphDB instance to connect to. Configure that instance with the following two environment variables.

• ULOAPPS_REMOTE_SERVER is the GraphDB server URL, e.g. http://graphdb:7300.

• ULOAPPS_REMOTE_REPOSITORY is the name of the GraphDB repository to connect to.
