-------------------------------------
Please could you provide a short data file that shows the problem for you.
> tdbdump / tdbloader sequence corrupts rdf:type predicates
> ---------------------------------------------------------
>
> Key: JENA-1000
> URL: https://issues.apache.org/jira/browse/JENA-1000
> Project: Apache Jena
> Issue Type: Bug
> Components: TDB
> Affects Versions: Jena 2.12.1, Jena 2.13.0
> Environment: Tested with tdbloader and tdbloader2 versions 2.12.1 and
> 2.13.0 on Windows/Sun Java 1.7.0_60 and CentOS 6.3/OpenJDK 1.8.0_25. tdbdump
> was 2.12.1 on CentOS 6.3/OpenJDK 1.8.0_25.
> Reporter: Donald Pellegrino
> Priority: Critical
>
> Steps to reproduce:
> 1. A TDB database was exported to N-Quads with tdbdump.
> 2. The dump file was then imported into a new TDB database with tdbloader2.
> 3. Observe that all rdf:type predicates were replaced with the same randomly
> selected predicate.
> Work-around:
> A work-around was to run a DELETE/INSERT SPARQL command to reassign rdf:type
> predicates after the load:
> DELETE { ?s custom:200501898-4-1 ?o }
> INSERT { ?s rdf:type ?o }
> WHERE {
> ?s custom:200501898-4-1 ?o
> }
> Testing:
> The behavior was consistent across multiple reloads of the same dump file.
> tdbloader and tdbloader2 were both used for loads and they were run on both
> Windows and Linux with the same results.
> Note that this is a Critical issue as it leads to silent corruption of user
> data.
