Foreword
The standard proposed by the People's Republic of China Ministry of Education.

Introduction
In the process of the implementation of online education, often involves learning object describes. This standard specifies the learning objects
Description method, the purpose is to help learners, educators or automated software for learning objects to find, evaluate, acquire and use. with
In the development of a unified directory system in the process, give full consideration to the learning objects and their metadata usage scenarios presence of cultural and linguistic diversity
, And promote the sharing and exchange of learning objects.
By defining a common conceptual data model, this standard to ensure a higher degree of semantic interoperability between bound learning object metadata
Operability. Thus, the conversion between different bindings will be straightforward.
The standard provides a basic metadata model, on top of this can create a variety of different applications, such as. for storing learning resources
Source of educational resources, courseware authoring tool for making and playing courseware for teaching management platform.

Learning Object Metadata
1 Scope
This standard specifies the learning object metadata data elements. Also it provides a conceptual data model for the definition of learning objects
Examples of metadata structures. For this standard, a learning object is defined as anything that can be used for learning, education and training and non-digital numbers
entity.
For this standard, learning object metadata instance describes a suitable learning object related features. These features can be divided into
9 categories. general, survival, meta - metadata, technology, education, rights, relationship, commentary and classification.
Linguistic diversity of the standards required by the conceptual data model allows the description of the learning objects and learning object metadata instance.
This conceptual data model defines the data elements of learning object metadata instance.
The standard is expected by reference to other standards implementation-defined data pattern description, so that learning object metadata instance can be learned
Learning technology system to manage, locate, evaluate or exchange learning objects.
This standard does not define how learning technology system represents or learning object metadata instance.
