LOM Standard is a multi-part standard that specifies Learning Object Metadata, trough a conceptual data schema that defines the structure of a metadata
instance for a learning object .
For this Standard, a learning object is defined as any digital or non-digital entity that may be used for learning, education or training.
A metadata instance for a learning object describes relevant characteristics of the learning object to which it applies. Data elements describe a
learning object and are grouped into categories. The LOM data model is a hierarchy of data elements, including aggregate data elements and
simple data elements, the leaf nodes of the hierarchy.
Its schema consists of nine such categories, each of them structured following a hierarchic architecture:
- The General category groups the general information that describes the learning object as a whole.
- The Life cycle category groups the features related to the history and current state of this learning object and
those who have affected this learning object during its evolution.
- The Meta-Metadata category groups information about the metadata instance itself (rather than the learning object that the metadata instance describes).
- The Technical category groups the technical requirements and technical characteristics of the learning object.
- The Educational category groups the educational and pedagogic characteristics of the learning object.
- The Rights category groups the intellectual property rights and conditions of use for the learning object.
- The Relation category groups features that define the relationship between the learning object and other related learning objects.
- The Annotation category provides comments on the educational use of the learning object and provides information on when and by whom the comments were created.
- The Classification category describes this learning object in relation to a particular classification system.
