                      throws RDFException

Retrieve sub-model from res:s point of view.

Parameters:

model - Source Model

buffer - Buffer-model

res - "Root"

depth - traverse-depth of Resource (Metadata)

Returns:

Sub-model - same as param buffer

Throws:

RDFException - Description of the Exception

getHierarchy

public static Model getHierarchy(Model model,
                                 Model buffer,
                                 Resource res,

                                 int resDepth)
                          throws RDFException

Retrieve sub-hierarchy from res:s point of view. res should be an IMSCP Container.

Parameters:

model - Source Model

buffer - Buffer-model

res - "Root"

itemDepth - traverse-depth of Hierarchy/Items (Organization)

resDepth - traverse-depth of Resource (Metadata)

Returns:

Sub-model - same as param buffer

Throws:

RDFException - Description of the Exception

To do:

Need to check IMS Container?

remove

public static void remove(Model model,
                          Resource res)
                   throws RDFException

Remove resource and its sub-model from model

Parameters:

model - Model

res - Resource to remove

Throws:

RDFException

To do:

Check if IMSCP Container?

duplicate

public static Statement duplicate(Model model,
                                  Statement stm)
                           throws RDFException

Create and add a duplicate of the branch marked by stm. If the subject of that statement is an RDF-Container the duplicate will be inserted at current ordinal+1. Values (leaf-nodes) are NOT duplicated. Language of duplicated (empty) Literals are preserved.

Parameters:

model - Model

stm - Statement of branch to be duplicated.

Returns:

the Statement marking the duplicated branch.

Throws:

RDFException

main

public static void main(String[] args)
