In the conventional process of digital resources polymerization, the libraries often use different hardware platforms, operating systems, communication protocols, database systems and other data description standards, implement independent maintenance and management of library resources, resulting in a large number of distributed heterogeneous data formation. Linked Data, as a lightweight way in semantic web, could use a unified way to identify resources and make a deep association, realizing the polymerization of digital library resources. It can not only achieve the full sharing of digital resources, but also benefit for the updating and improvement of libraries’ service system.This study has made progress on the basis of linked data aggregation and services:(1) New pathway of resource aggregation in digital libraries:linked data. We can realize different problems in digital resource aggregation through literature, questionnaires, interviews, comparative and other methods, exploring new a new way-linked data to accomplish the association of digital library resources. I believe that:linked data can help us accomplish the universal edifying and correlation of digital library resources, realize the deep association of digital resources, and promote users’ resource retrieval and information accessing.Digital library resources association based on linked data. In this section, we can discover the current status of digital library resource’s polymerization through questionnaires, interviews and other research methods. We discover that based on the principles of sustainability, using SFX, Web Service, P2P and other kinds of technology to realize the deep polymerization of digital library resources. With the use of Drupal which built-in linked data mode to build the library catalog navigation, we can complete the application associated with the linked data presented.(2) The innovative service of digital libraries based on linked data. On the basis of literature research, the author explored the knowledge discovery and the knowledge service of digital library, and got across the personality making service, push service, digital virtual reference service and innovative services, etc. of the current libraries. The combination of the real-time reference service, the asynchronous reference service, the collaborative reference service, and the hierarchical reference service can provide a better reference service for the digital library. By using design-based research, make the theory of resources integration and innovative service of the digital library based on linked data can provide a better user consulting servicesThrough researching the resource polymerization and services of digital library base on linked data, we have deeply realized that there are many problems in traditional resource integration, on the basic of that, we make a deep research on linked data. Digital library resource polymerization based on linked data can realize knowledge discovery, knowledge services, personalized information customization and resource pushing, and the virtual reference consulting of digital libraries based on the facilitate of deep aggregation, more over promote resource sharing and the continuous innovation and improvement of knowledge service system in digital libraries with the use of linked data.
