The presence of owl:imports in a document creates new graphs with data imported from unknown third parties

[MaillPierre]

Expected Behavior

Loading a file using the LOAD query only adds the data of the file to the server

Actual Behavior

Loading a file containing an ontology using the owl:imports property also loads the RDF files that can be dereferenced at the URIs object of the property.

Steps to Reproduce the Problem

1. Launch a fresh instance of corese server with java -jar corese-server-4.4.0.jar -su
2. Executing SELECT DISTINCT ?g { GRAPH ?g { ?s ?p ?o } } returns no graph. Executing SELECT (count(*) AS ?count) { ?s ?p ?o } returns 0.
3. Execute the SPARQL query LOAD <https://raw.githubusercontent.com/Wimmics/IndeGx/coreseDebug/rules/indegx_vocabulary.ttl> to load a file into the default graph
4. Executing SELECT DISTINCT ?g { GRAPH ?g { ?s ?p ?o } } returns the following list of graphs:

<http://www.w3.org/2000/01/rdf-schema#>
<http://www.w3.org/ns/dcat#>
<http://www.w3.org/ns/earl#>
<http://www.w3.org/ns/prov-dictionary#>
kg:default

<http://www.w3.org/ns/dqv#>
<http://www.w3.org/2004/02/skos/core>

Each graph contains the content of its corresponding ontology.
Executing SELECT (count(*) AS ?count) { GRAPH kg:default{ ?s ?p ?o } } shows that some content is added to the default graph.
The original file contains 252 lines but executing SELECT (count(*) AS ?count) { ?s ?p ?o } returns 5938 triples.

Suggested solutions

• Adding a setting to control this behavior.
• Disabling this behavior by default.

Hello Pierre,

Thank you for reporting this issue and providing detailed information. We have considered your suggestion and worked on a resolution.

The problem has been addressed by introducing a new property: DISABLE_OWL_AUTO_IMPORT. To utilize this feature, please create a corese.properties file and add the following line: DISABLE_OWL_AUTO_IMPORT = true. Then, start the Corese-Server or Corese-GUI with the -init corese.properties option.

This feature will be included in the next release of Corese. In the meantime, if you need it, I provide you a jar file that contains this functionality (Corese-Server, Corese-Gui).

I will not close this ticket immediately. Could you please confirm if this resolves your issue and works as expected?

[MaillPierre]

This solves the issue, thank you.

Hello Pierre,

In the upcoming release of Corese (>= 4.4.2), the import of owl:imports will be disabled by default.

If you wish to enable it, you will need to use a property file. Here's an example of a configuration file that enables the import of owl:imports (>= 4.4.2):

# Enenable the import of owl:imports
ENABLE_OWL_AUTO_IMPORT = true

I hope this will be helpful for you.

+1 pour que la configuration par défaut soit en compatibilité ascendante Fabien Gandon, http://fabien.info

Okay, I restored the old default behavior.

Est-ce qu'il serait pertinent de le désactiver par défaut dans le cadre de la commande "convert" de Corese-Command ?
