org.apache.jena.permissions.SecuredAssembler

All Implemented Interfaces:

Assembler, AssemblerConstants

public class SecuredAssembler
extends ModelAssembler
implements AssemblerConstants

Assembler for a secured model.

The assembler file should include the following

 <> ja:loadClass    "org.apache.jena.permission.SecuredAssembler" .

 sec:Model rdfs:subClassOf ja:NamedModel .

 sec:evaluator rdfs:domain sec:Model ;
               rdfs:range sec:Evaluator .
 

The model definition should include something like.

 my:secModel a sec:Model ;
    sec:baseModel my:baseModel ;
    ja:modelName "http://example.com/securedModel" ;
    sec:evaluatorFactory "org.apache.jena.permission.MockSecurityEvaluator" ;
    .
 

Terms used in above example:

my:secModel

The secured model as referenced in the assembler file.

sec:Model

Identifes my:secModel as a secured model

sec:baseModel

Identifies my:baseModel as the base model we are applying permissions to

my:baseModel

a ja:Model (or subclass) defined elsewhere in the assembler file

ja:modelName

The name of the graph as it will be addressed in the permission environment (see ja:NamedModel examples from Jena)

sec:evaluatorFactory

Identifies "org.apache.jena.permission.MockSecurityEvaluator" as the java class that implements an Evaluator Factory. The Factory must have static method getInstance() that returns a SecurityEvaluator.

or if using an evaluator assembler

 my:secModel a sec:Model ;
    sec:baseModel my:baseModel ;
    ja:modelName "http://example.com/securedModel" ;
    sec:evaluatorImpl ex:myEvaluator;
    .

 ex:myEvaluator a sec:Evaluator ;
    ex:arg1 "argument 1 for my evaluator constructor" ;
    ex:arg2 "argument 2 for my evaluator constructor" ;
    .
 

Terms used in above example:

my:secModel

The secured model as referenced in the assembler file.

sec:Model

Identifies my:secModel as a secured model

sec:baseModel

Identifies my:baseModel as the base model we are applying permissions to

my:baseModel

a ja:Model (or subclass) defined elsewhere in the assembler file

ja:modelName

The name of the graph as it will be addressed in the permission environment (see ja:NamedModel examples from Jena)

sec:evaluatorImpl

Identifies ex:myEvaluator as a SecurityEvaluator defined elsewhere in the assembler file. It must subclass as a sec:Evaluator.

ex:arg1 and ex:arg2

Arguments as defined by the user defined security evaluator assembler.
