BASIL

BASIL is designed as middleware system that mediates between SPARQL endpoints and applications.

With BASIL you can build Web APIs on top of SPARQL endpoints.

BASIL stores SPARQL queries and builds APIs with standard and customizable formats.

Run

Latest runnable jar can be downloaded from the releases section.

TDB2 backend (default)

An example configuration file can be found in the project root folder (basil-tdb2.ini). An example log4j configuration file is at server/src/test/resources/log4j.xml.

Execute:

$ java -jar -Dbasil.configurationFile=./basil-tdb2.ini -Dlog4j.configurationFile=./log4j2.xml basil-server-VERSION.jar -p 8080
#1: welcome to the world's helthiest food
#2: basil is starting on port 8080
#3: done
#4: enjoy

MySQL backend (legacy)

You need to:

• Have a MySQL server.
• Prepare a database running the db.sql queries (at the root of the codebase).
• Prepare the configuration file (the connection parameters), see this file as an example.
• Prepare a log4j2 configuration file (if you want logging). See this file as an example.

When ready, execute:

$ java -jar -Dbasil.configurationFile=../basil.ini -Dlog4j.configurationFile=src/test/resources/log4j2.xml basil-server-0.3.0.jar -p 8080
#1: welcome to the world's helthiest food
#2: basil is starting on port 8080
#3: done
#4: enjoy

Usage

BASIL is a system based on a Web API for creating and managing a stack of Web APIs on top SPARQL endpoints. On its own, BASIL does not come with a graphic user interface. Instead, it can be fully controlled via its API. See the cURL tutorial for details.

Build

The basil project is managed and built with Maven.

mvn clean install

Note: to also run tests, you need an active internet connection (as they use public SPARQL endpoints). If you want to skip tests, you can:

mvn install -DskipTests

Releasing

The following command will pack a release, sign the artefacts, and push them to maven central.

mvn deploy -DperformRelease=true
