Error importing data into GraphDB with curl

[subotic]

Steps:

1. Load data into GraphDB and
2. Run upgrade script

Error:

com.ontotext.trree.consistency.ConsistencyException: Consistency check empty_string_0 failed:
http://rdfh.ch/0807/21BTn-EJRpSFteiiOvApbg/values/V_m80QSURbOwKg2O6vzRyw http://www.knora.org/ontology/knora-base#valueHasString ""^^<http://www.w3.org/2001/XMLSchema#string>

Since there is no knora-base#valueHasString property on the resource before the upgrade, I guess it was added during upgrade.

@benjamingeer I will send you a link per email, where you can download the data.

When you implement the fix, could you please base your branch on b4ce837, so that we can then release v10.0.1. Afterward, you can merge it into develop.

This seems to be a bug in GraphDB's parsing of the TriG input file. The input data contains a newline, not an empty string. If we import it via the GraphDB workbench, it works, but if we use curl, it doesn't.

Ontotext are looking into this. For now, the workaround is to use the Manual Upgrade procedure, and to upload the transformed data to GraphDB using the GraphDB workbench instead of upload-repository.sh.

[benjamingeer]

Ontotext have kindly informed us that curl strips newlines from an upload when you use the -d/--data option (!) and you have to use --data-binary instead.

great, thanks!
