```
public int getPropSerializationType(String propURI)
```
    Answers if the given property has to be considered when serializing this individual in a minimized way, and if not ignore-able, whether its value should be presented in its full form or can be reduced. The return value must be one of PROP_SERIALIZATION_OPTIONAL, PROP_SERIALIZATION_REDUCED, or PROP_SERIALIZATION_FULL. It can be assumed that the given property is one of those returned by getPropertyURIs().
    Decision criterion should be if the value of this property is absolutely necessary when this resource is being sent to a remote node. If the subclass rates it as unlikely that the receiver side would need this info, the answer should be PROP_SERIALIZATION_OPTIONAL in favor of lower communication traffic and higher performance even at risk of a possible additional query on the receiver side for fetching this info. With the same rationale, if a property should be included in the process of serialization, it is preferable to include it in a reduced form; in this case the return value should be PROP_SERIALIZATION_REDUCED, otherwise PROP_SERIALIZATION_FULL can be returned. Subclasses should normally overwrite this method as this default implementation returns always PROP_SERIALIZATION_FULL.
  - getStaticFieldValue

public boolean serializesAsXMLLiteral()
```
    Resources to be serialized and parsed as rdf:XMLLiteral must overwrite this method and return true. Serializers and parsers can use this as a hint.
  - setResourceComment
```
public void setResourceComment(String comment)
```
    Set the Resource comment. Convenient method to set rdfs:comment.
    
    Parameters:
    
    comment - the comment.
  - setResourceLabel
```
public void setResourceLabel(String label)
```
    Set the Resource label. Convenient method to set rdfs:label.
    
    Parameters:
    
    label - the label.
  - addMultiLangProp
```
public void addMultiLangProp(String propURI,
                             LangString ls)
```
    Add a new String literal (with optional language tag) to a multi-value property.
    
    Parameters:
    
    propURI - URI of the property. Typical values are PROP_RDFS_LABEL or PROP_RDFS_COMMENT.
    
    ls - The String to add.
  - getMultiLangProp
```
public LangString getMultiLangProp(String propURI,
                                   String lang,
                                   boolean includeDefault)
```
    Get a String literal (with optional language tag) from a multi-value property.
    
    Parameters:
    
    propURI - URI of the property. Typical values are PROP_RDFS_LABEL or PROP_RDFS_COMMENT.
    
    lang - The preferred language. Should be one of the constants defined in LangString, e.g. LangString.LANG_ENGLISH.
    
    includeDefault - If no String with the preferred language could be found, this variable determines if a String without language specifier could also be returned.
    
    Returns:
    
    The value of the multi-value property.
  - setProperty
```
public boolean setProperty(String propURI,
                           Object value)
```
    Adds a statement with this resource as the subject, the given propURI as the predicate and the given value as the object. Subclasses must override this in order to decide if the statement to be added fits the general class constraints. If not, the call of this method should be ignored. For each property only one single call may be made to this method, unless subsequent calls to this method for setting the value of the same property are treated as an update for an update-able property. Multi-valued properties must be set using an instance of List. The differentiation, if a such list should be treated as an rdf:List, can be made with the help of isClosedCollection(String). The default implementation here accepts all property-value pairs blindly except for rdf:type which is handled if the value is a type URI, a Resource or a java.util.List of them.
    Note: The setting of the property rdf:type is being handled by this class via the final methods addType(String, boolean), getType(), and getTypes(). Although these methods give the view of handling type URIs as strings, but in reality the types are stored as direct instances of this class. So, the subclasses should ignore calls for setting rdf:type; if not, then the subclass must pay attention that the value should be a List of direct instances of this class so that (1) the toString() method returns just the URI and (2) the serializers get no problems with the value. Also, settings via subclasses may be overwritten by this class if a subsequent call to addType(String, boolean) is made.
    
    Returns:
    
    true if the property changed as a result of the call
  - setPropertyPath
```
public boolean setPropertyPath(String[] propPath,
                               Object value)
```
    Set the given value at the end of the given property path, but does not force the setting.
    
    See Also:
    
    setPropertyPathFromOffset(String[], int, Object, boolean)
  - setPropertyPath
```
public boolean setPropertyPath(String[] propPath,
                               Object value,
                               boolean force)
```
    Set the given value at the end of the given property path.
    
    See Also:
    
    setPropertyPathFromOffset(String[], int, Object, boolean)
  - setPropertyPathFromOffset
```
public boolean setPropertyPathFromOffset(String[] propPath,
                                         int fromIndex,
                                         Object value,
                                         boolean force)
```
    Change or add the Resource at the end of the given property path to the given value. This method starts from this Resource and follows the given property path through the RDF graph. If a property from the path does not yet exist, a new anonymous Resource is automatically created. At the end of the property path, the given value is set as RDF object with the last property from the path as RDF predicate.
    
    Parameters:
    
    propPath - The set of properties defining the path through the RDF graph.
    
    fromIndex - The property path is evaluated from this index on; if 'fromIndex' is greater than zero, then some entries at the beginning are just ignored.
    
    value - The value to set at the end of the property path
    
    force - Determines if setting the value has to be forced. If true, changeProperty(String, Object) is called, otherwise setProperty(String, Object) is called.
    
    Returns:
    
    true, if the operation was successful.
  - toString
```
public String toString()
```
    Get a String representation of this Resource; returns the URI.
    
    Overrides:
    
    toString in class Object
  - toStringRecursive
```
public String toStringRecursive()
```
    Debug method: get a string of this RDF graph.
    
    Returns:
    
    The graph as string.
  - toStringRecursive
```
public String toStringRecursive(String prefix,
                                boolean prefixAtStart,
                                Hashtable visitedElements)
```
    Debug method: get a string of this RDF graph.
    
    Parameters:
    
    prefix - Indention string that every line starts with.
    
    prefixAtStart - True iff the first line should start with the prefix string.
    
    Returns:
    
    The graph as string.
  - unliteral
```
public void unliteral()
```
    Make this object not being an XMLLiteral
  - literal
```
public void literal()
```
    Make this object an XMLLiteral
