| With the rapid development of Internet and information technology, various types of digital resources became more and more, easy sharing and retrieval made it easier for the majority of users to access these digital resources.But as the numbers and types of digital resources become more, and differences between database application systems, information data formats and storage forms, and knowledge associated with low, certain differences between the retrieval languages and approaches, all these factors give the users great inconvenience to use digital resources.In order to fully utilize these resources carry out effective integration of resources has become one of the key elements of digital library research. As these digital resources located in different regions and each of them has mass data, quickly and accurately obtaining the necessary data from those resources requires digital library provides users one-stop search service to build a convenient and rapid information bridge between users and data.This paper divided resources into four types, which are business database resource, local self-built special resource, OAI metadata resource and Internet resource Based on these resources this paper proposed adoption of Service Oriented technology to publish the search of different resources as service, thereby enables resources to provide external services.Based on the concept of SOA, this paper design and implement integration of digital resources and services system to meet user's needs.It integrates the Web Service-based resource integration service, unified search service based on Ajax and Internet analysis, local resources retrieve and browser serevice, extended link services and digital resources deliver service. System has a high ability to retrieve and integrate resource, implemented one-stop resource retrieval and visualization management.This system is cross platform, scalable, easy to maintain, it has high practical values. |
