摘要 在基于服务域划分的层次型数字图书馆网格服务发布结构基础上,提出面向用户的多阶段数字图书馆网格服务发现机制,利用“我的服务”阶段、主服务域→子服务域阶段、主服务域间转发阶段和根域→主服务域阶段完成服务发现。

Abstract :Based on a hierarchical DL grid service publication structure, this paper adopts the user-oriented and multi-stage service discovery model, which segmenting the service discovery into “my service” stage, main service domain to service sub-domain stage, transfer within main service domain stage and root domain to main service domain stage.
