Förkortningar som används EUN : Europeiska skoldatanätetELR : Europeiska skoldatanätets ämnesordslistorIEEE : ett av flera standardiseringsorgan LO : Learning objectLOM : Learning object model , 85 elementsDC : Dublin Core metadatamodellMetadata : ”Information om informationen”Mandatory elements : ”tvingande fält ”

  4. 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).

  6. 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

  7. 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.

  9. 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 LO’s content. NOTE: Mandatory element ‘9.4 Classification.Keyword’ 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.

LO metadata ex Celebrate Title of resource Reaction Subject ELR Thesaurus chemistry Language of resource English, Hungarian Abstract of resource By means of a test series we can prove how the acid and basic substances change the colour of indicator. The curriculum interpretes the reaction of solutions and it shows how various reactions can be comparised to each other.

  15. www.eun.org Celebrate projektets webbplats hittas från , 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).
