GB/T 29811.3-2018Information technology—Learning, education and training—Learning system architecture and services interfaces—Part 3: Resource accessing services interfaces (English PDF)

3.1 Service

A well-defined, self-contained functional unit whose existence does not depend on the context of the system or the state of other services.

3.2 Member

The attribute definitions or dynamic functions that an interface has can be methods, properties, events, and index indicators.

Note: An interface definition can contain zero or more members.

4.1 Overview

The interface gives a system behavior model and does not enforce binding to a specific language. For ease of understanding, Appendix A gives the service Java language binding for interfaces.

This part divides the service interface into. learning object management service interface, learning content packaging service interface, learning design service interface, testing Question information service interface and resource statistics service interface.

This section defines interfaces using four categories. member, return value type, parameter description, and description.
