Import now, think later. A system that allows importing data files, saving the contents, and adding metadata during and after import.
For now, only CSV files are supported. The first line is expected to contain headers. The headers are converted to URIs and used as predicates when the records are saved to a triple store.
After uploading, a mapping screen is shown to allow customization of the mapping from header name to predicate URI. Here, it will also be possible to skip columns, or add additional metadata like uniquely identifying values.
After importing, the records can be listed, as well as the properties.
Optionally, for triple store, the application can connect to a running instance of GraphDB. In this case, GraphDB's front end also allows browsing and querying the data.
Install the Lightbend Activator and add the bin/ to your $PATH for convenience.

Set the same name in the conf/application.conf file under importnow.remoterepo.repo.
Check that importnow.remoterepo.url is correct and leads to your GraphDB instance.
