    • init

      public static void init()

    • registerDataset

      public static void registerDataset(org.apache.jena.rdf.model.Resource r, org.apache.jena.assembler.Assembler a)
      Register an assembler that creates a dataset

    • registerModel

      public static void registerModel(org.apache.jena.rdf.model.Resource r, org.apache.jena.assembler.Assembler a)
      Register an assembler that creates a dataset

    • register

      public static void register(org.apache.jena.assembler.assemblers.AssemblerGroup g, org.apache.jena.rdf.model.Resource r, org.apache.jena.assembler.Assembler a, org.apache.jena.rdf.model.Resource superType)
      Register an additional assembler

    • registerAssembler

      public static void registerAssembler(org.apache.jena.assembler.assemblers.AssemblerGroup group, org.apache.jena.rdf.model.Resource r, org.apache.jena.assembler.Assembler a)
      register

    • readAssemblerFile

      public static org.apache.jena.rdf.model.Model readAssemblerFile(String assemblerFile)
      Read a file and make ready for use with assemblers. It calls prepareForAssembler(org.apache.jena.rdf.model.Model).

    • prepareForAssembler

      public static org.apache.jena.rdf.model.Model prepareForAssembler(org.apache.jena.rdf.model.Model model)
      Add any extra information to the model. Such information includes registration of datasets (e.g. TDB1, TDB2) done by register(org.apache.jena.assembler.assemblers.AssemblerGroup, org.apache.jena.rdf.model.Resource, org.apache.jena.assembler.Assembler, org.apache.jena.rdf.model.Resource) (registerDataset(org.apache.jena.rdf.model.Resource, org.apache.jena.assembler.Assembler), registerModel(org.apache.jena.rdf.model.Resource, org.apache.jena.assembler.Assembler) and adding subclass relationship used for models. It avoids directly modifying Assembler.general.
      Parameters:
      model -
      Returns:
      Model The same model after modification.

    • addRegistered

      @Deprecated(forRemoval=true) public static org.apache.jena.rdf.model.Model addRegistered(org.apache.jena.rdf.model.Model model)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Use prepareForAssembler(Model)

    • parseContext

      public static Context parseContext(org.apache.jena.rdf.model.Resource r)
      Look for and build context declarations. e.g. 
       root ...;
   ja:context [ ja:cxtName "arq:queryTimeout";  ja:cxtValue "10000" ];
   ...
      Short name forms of context parameters can be used. Setting as string "undef" will remove the context setting. Returns null when there is no JA.context on the resource.

    • loadData

      public static void loadData(DatasetGraph dataset, org.apache.jena.rdf.model.Resource root)
      Process ja:data.

      The object value refers to a file, either by string name or a file: URI. If it is a string, a relative filename will be relative to the JVM current directory. If it is a file: URI, a relative filename will be relative to the assembler file and it's base URI.

    • mergeContext

      public static void mergeContext(org.apache.jena.rdf.model.Resource r, Context context)
      Look for and merge in context declarations. e.g. 
       root ...;
   ja:context [ ja:cxtName "arq:queryTimeout";  ja:cxtValue "10000" ];
   ...
      Short name forms of context parameters can be used. Setting as string "undef" will remove the context setting.
