Getting Started with DSP-API

Running DSP-API locally or on a server requires Docker, which can be freely downloaded. Please follow the instructions for installing Docker Desktop.

Additional software:

These can be easily installed on macOS using Homebrew:

$ brew install git
$ brew install expect
$ brew install sbt

To install Adoptopenjdk Java 11 with Homebrew:

$ brew tap AdoptOpenJDK/openjdk
$ brew cask install AdoptOpenJDK/openjdk/adoptopenjdk11

To pin the version of Java, please add this environment variable to you startup script (bashrc, etc.):

export JAVA_HOME=`/usr/libexec/java_home -v 11`

Choosing a Triplestore

DSP-API requires a standards-compliant RDF triplestore. A number of triplestore implementations are available, including free software as well as proprietary options.

DSP-API is designed to work with any standards-compliant triplestore. It is primarily tested with Apache Jena Fuseki, an open source triplestore.

Other triplestores are planned.

Running the DSP-Stack

Use git to clone the DSP-API repository from Github.

Then from inside the cloned DSP-API repository folder, run:

$ make stack-up

Creating Repositories and Loading Test Data

To create a test repository called knora-test and load test data, run:

$ make init-db-test

The scripts called by make can be found under webapi/scripts. You can create your own scripts based on these scripts, to create new repositories and optionally to load existing DSP-compliant RDF data into them.

If you need to reload the test data, you need to stop and delete the running Apache Fuseki instance. Make sure you don't delete important data. To stop the instance and delete the repository, run the following command:

$ make stack-down-delete-volumes

after which you can start the stack again with make stack-up, recreate the repository and load the data with make init-db-test.
