I've multiple data sources (files or API data). I want to integrate all these sources using one common ontology.
I've started using Karma Information Integration Tool; however, I'm facing some execution errors with its service.
I'm looking for alternative solution. I wonder if OpenRefine still supporting RDF and ontologies ?
It's very important for us to have a defined mapping between ontology and data source (e.g., a web service). This allows us to apply automatically mapping every time we get new data from the source.
