|
| - queries
|_ my-transformation-latest.sparql
Be sure that at least a {my-transformation}-latest.ttl and {my-ouput-kg}-latest.ttl is presented at the specified paths.
Polifonia KG Sparql Endpoint will point to these locations while harvesting data.
You can manually test latest versions of KG if you have kgdd installed with following commands:
kgdd -t ./places_etl/kg/test/testbed-latest.json -f ./places_etl/kg/polifonia-kg-places-latest.ttl
kgdd -t ./harmonic_sim_etl/kg/test/testbed-latest.json -f ./harmonic_sim_etl/kg/polifonia-kg-harmonic-sim-latest.ttl
