This is a description of a FireSat mission design expressed as OWL ontology files (in ttl format).
Notice that the OWL files are in the folder src/owl and organized in subfolders based on their namespaces.
The file src/owl/catalog.xml contains a mapping between the files' logical namespaces and thier physical locations.
While most of the files represent assertions, i.e., asserted facts, those in folder src/owl/opencaesar.io/examples/firesat/bundle represent entailments generated by a DL (Description Logic) reasoner from the assertions.
The folder src/sparq contains some examples of SPARQL queries that can be run against this dataset. You can write others by adding more *.sparql files in the same folder.
A build.gradle script is added with some convenient tools to work with Fuseki as can be seen below.
git clone https://github.com/melaasar/firesat.git
cd firesat
- You need JDK 11+ installed in the environment
Run the following
./gradlew startFuseki
./gradlew query
./gradlew stopFuseki
Inspect results of query in folder: build/results
On Windows, replace ./gradlew by ./gradlew.bat
Start a new Fuseki instance if one is not already started
./gradlew startFuseki
A Fuseki instance can now be accessed at URL: http://localhost:3030
You need to run this once at the start before running any action (like load or query) involving Fuseki
Stop a running Fuseki instance if one is already running
./gradlew stopFuseki
You need to run this once at the end after you are done running actions (like load or query) involving Fuseki
Pre-req: A Fuseki server with a firesat dataset must be running at http://localhost:3030/firesat (see Start Fuseki Server below)
Load a dataset to a running Fuseki instance
./gradlew load
Pre-req: A Fuseki server with a firesat dataset must be running at http://localhost:3030/firesat (see Start Fuseki Server below)
Run SPARQL queries in src/sparql on a dataset loaded in Fuseki
./gradlew query
Results will be in the folder build/results
