public static void add(String prefix,
                       String namespace)
```
    Programmatically adds a new prefix to be regarded as an "extra" prefix. These are prefixes that are assumed to be valid even if they haven't been declared in the current ontology. This method has no effect if the prefix was already set before.
    
    Parameters:
    
    prefix - the prefix to add
    
    namespace - the namespace to add
  - add
```
public static void add(org.apache.jena.rdf.model.Resource resource)
```
    Attempts to add an extra prefix for a given Resource. This does nothing if the prefix does not exist or is empty.
    
    Parameters:
    
    resource - the resource to get the namespace of
  - createPrefixMappingWithExtraPrefixes
```
public static org.apache.jena.shared.PrefixMapping createPrefixMappingWithExtraPrefixes(org.apache.jena.rdf.model.Model model)
```
    Creates a PrefixMapping that uses the prefixes from a Model plus any extra prefixes (unless they overlap with those from the Model).
    
    Parameters:
    
    model - the Model to construct the PrefixMapping from
    
    Returns:
    
    a new PrefixMapping instance
  - getExtraPrefixes
```
public static Map<String,String> getExtraPrefixes()
```
    Gets a Map from prefixes to namespaces. The result should be treated as read-only.
    
    Returns:
    
    the extra prefixes
