After exporting starwars kit data I see the following: sw:population "NA"^^xsd:integer ;
Which then causes this error on loading into a new database:
Failed to load data to "kit": There was a fatal failure during preparation of d28c78bb-480f-4278-8b89-11cd2bb96930: 'NA' is not a valid value for datatype http://www.w3.org/2001/XMLSchema#integer [L787]
You just use strict.parsing=false as a database option.
The invalid data is purposeful, the kit is from a presentation at KGC several years ago where rules were used to perform data cleansing and uplift, leaving the source data in tact, for better lineage and traceability.
