David W. Lotts commented on RYA-93:
-----------------------------------
If you have inferencing ("query.infer") turned on (post your configuration),
then post the query plan. I think the DirectExample does that by default:
extras/indexingExample/src/main/java/RyaDirectExample.java
>From
>common/rya.api/src/main/java/mvm/rya/api/RdfCloudTripleStoreConfiguration.java
These are the properties:
public static final String CONF_INFER = "query.infer";
public static final String INFER_INCLUDE_INVERSEOF = "infer.include.inverseof";
public static final String INFER_INCLUDE_SUBCLASSOF =
"infer.include.subclassof";
public static final String INFER_INCLUDE_SUBPROPOF = "infer.include.subpropof";
public static final String INFER_INCLUDE_SYMMPROP = "infer.include.symmprop";
public static final String INFER_INCLUDE_TRANSITIVEPROP =
"infer.include.transprop";
> owl:SymmetricProperty/owl:inverseOf failed
