Cloud-based digital library service model
|Keywords||Cloud computing Digital library Service model|
Digital library whose production and development is relied on modern information technology is a kind of library modernization development form. With the development and popularization of internet and computer technology, digital library moves forward rapidly. Cloud computing is a kind of production integrated with series of computer technology which has developed to a certain stage. It will make far-reaching implications to digital library and even other fields. Cloud computing is still in the stage of rapid development. So in this article the origin and concept of cloud computing will be summarized in detail, the character , basic structure of the cloud computing and its application and impact in each field will be analyzed strongly. In the cloud computing environment, the construction and service of digital library has changed greatly. The cloud storage based on digital library,the digital library infrastructure integration and construction based on cloud service, and even the library automation based on cloud computing, all of these need to research deeply in library field in the cloud computing era. Besides,the changes of digital library service model based on cloud computing are also the one of the important content. In this article three kinds of service model is proposed:personalized cloud platform service model based on the needs of the users, user sdi active push-service model and sharing cloud platform service model. Structure model is designed respectively, the working process and model of service model is explained, and their application scope is analyzed in this article.
