DublinCore (Opencast :: dublincore 7.4 API)

All Known Implementing Classes:

DublinCoreCatalog
```
@ParametersAreNonnullByDefault
public interface DublinCore
```
This interface is mainly intended to encapsulate Dublin Core metadata, but it is also capable of maintaining proprietary metadata alongside the Dublin Core.
Dublin Core is an initiative to create a digital "library card catalog" for the Web. Dublin Core, in its simple form, is made up of 15 metadata (data that describes data) elements that offer expanded cataloging information and improved document indexing for search engine programs.
Two forms of Dublin Core exist: Simple Dublin Core and Qualified Dublin Core. Simple Dublin Core expresses properties as literal strings using just the 15 metadata elements from the Dublin Core Metadata Element Sets. Each element can have multiple values, but order is defined. Values may have an associated language.
Please see http://dublincore.org/documents/dces/ for further information.
Qualified Dublin Core increases the specificity of metadata by extending the set of properties (elements) and by adding information about encoding schemes. While enabling searches to be more specific, qualifiers are also more complex and can pose challenges to interoperability.
Please see http://dublincore.org/documents/dcmi-terms/ and http://dublincore.org/documents/dc-xml-guidelines/ Section 5 for further information.

Current limitations
- This interface assumes that Dublin Core metadata is stored as XML. According to the Dublin Core specification this is not necessary.
- Encoding schemes aren't fully supported yet.

  - LANGUAGE_UNDEFINED
```
static final String LANGUAGE_UNDEFINED
```
    Language code for properties without language information.
    
    See Also:
    
    Constant Field Values
  - LANGUAGE_ANY
```
static final String LANGUAGE_ANY
```
    Language code that matches any language.
    Use this code whenever you need values in all languages or you don't care about the language. Note that all methods taking this as a legal value for the language parameter are adviced to return at first a value for LANGUAGE_UNDEFINED if multiple values exist and only one value is wanted.

  - get
```
List<String> get(org.opencastproject.mediapackage.EName property,
                 String language)
```
    Get all values of a property, either in a certain language or in all contained languages.
    
    Parameters:
    
    property - the property qname
    
    language - a language code, LANGUAGE_UNDEFINED or LANGUAGE_ANY

```
    Get all values of a property no matter what language they have.
    
    Parameters:
    
    property - the property's expanded name

```
    Like get(EName, String) but returns only the first value of the list. This method is intended to be a convenience method for those properties that have only one value.
    Please note, that if you pass LANGUAGE_ANY, values with an undefined language are returned preferably.

    Returns:
    
    the value or null
  - getFirst
```
@Nullable
String getFirst(org.opencastproject.mediapackage.EName property)
```
    Get the first value of a property, no matter what language it is in. Like a call of getFirst(EName, String) with language = LANGUAGE_ANY. Please not that values with an undefined language are returned preferably.
    
    Parameters:
    
    property - the property's expanded name
    
    Returns:
    
    the value or null
    
    See Also:
