Metadata Application Profile

• The deliverable describes the Application
  Profile for the use of the LOM within the
  Celebrate community. It also provides a mapping
  from the ELR application profile, which is Dublin
  Core based, to the Celebrate Metadata Application
  Profile

5
CELEBRATE Elements

• There are two types of element subsets defined
  here the elements that should be filled in
• 1_every metadata instance (mandatory elements)
  and
• 2_ the elements that would be very useful to be
  filled (recommended elements).

Support variety of LO uses

• The application profile including
•  
• Management
• Searching and finding
• Technical interoperability
•  
• and description of properties of individual LOs
  including
•  
• Educational attributes
• Digital rights
• Technical features

Information model

• IEEE Learning Object Metadata standard (LOM) has
  been selected as basis for CELEBRATE metadata to
  achieve functionalities and to support
  interoperability between other metadata schemes.
  The information model for CELEBRATE metadata is
  similar that in LOM where metadata for described
  LO is stored in metadata element and actual
  content of an element is called a value. Values
  can be entered as free text, inserted in
  predefined format or they are selected from set
  lists which are called vocabularies.

8
Metadata Appendix A

• The information model groups metadata elements
  to nine categories
• 1_General,
• 2_Life Cycle,
• 3_Meta-Metadata,
• 4_Technical,
• 5_Educational,
• 6_Rights,
• 7_Relation,
• 8_Annotation
• 9_Classification.

85 elements

• There are 85 elements in CELEBRATE information
  model of which 21 are not containing values but
  are functioning as container elements that are
  grouping value elements together. Not all
  elements in information model are seen very
  useful for CELEBRATE metadata but they are there
  for compatibility with LOM and as optional
  elements they cause minimal disadvantage.

10
Ex General keyword 1.5

•  1.5 General.Keyword is intended to provide free
  text keywords describing the LOs content.
• NOTE Mandatory element 9.4 Classification.Keywor
  d is to be used in place of 1.5
  General.Keyword when values are derived from ELR
  Thesaurus (see paragraph 2.3.8 Classification).

11
Forts General Keyword

• 1.5 General. Keyword is a LangString (see
  paragraph 2.2.2 Data Types) element which gives a
  possibility to define the used language.
  Information Model (Appendix A) permits ten
  different 1.5 General. Keyword elements and
  data type LangString permits ten different
  languages for each individual element.
•  

12
Forts General Keyword

• The tagging user interface should be designed so
  it gives possibility to enter individual keyword
  in different languages in one element.The most
  specific terms descriptive of the LO's content
  should be used. Each term or phrase should use a
  separate keyword element and lengthy phrases
  should be avoided.

  www.eun.orgCELEBRATE is a 30-month, 5m
  Information Society Technology project supported
  by the European Commission. The main task is to
  create an innovative approach to teaching using
  eLearning technologies, based on a vision of what
  electronic content (resources, services and
  communication tools) may look like in the future.
  The project will provide schools with an online
  content database that includes multimedia assets
  for learning learning objects (LOs).
