---------------------------------------
Summary: 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 2.13.0, Jena 2.12.1
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.
