Digital Library

The librarians are to be dealing the digital library, the virtual library, the hybrid library and the library without wall with all the time. According Arms (2000), digital library can defined as a managed collection of information, with associated services, where the information is stored in digital formats and accessible over a network. A crucial part of this definition is that the information managed. Digital library is a library that provides in digital forms. Even though widely used digital library, hybrid library has just appeared in the digital library research in the UK. Hybrid library is a library that uses digital information and printed it up together and can be brought together in a single integrated information services that are

The ultimate goal is the data maintained in the repository without any damaged, lost or altered in bad faith. In addition, the data can also be found, extracted and serving the users and can be constructed and are comprehensible to user. The digital preservation issues also have the several goals. First goals is essential to get the repository is handled by any digital repository. Repository to support search and retrieval to improve access to information is a second goal. It is the one area that has received much attention. The next goals of the third and fourth are achieving required by digital preservation. Assume that institutional repositories, digital preservation is a challenging task for digital preservation is a complex process and there are many organization, management and technical issues that cannot be resolved. Because there are plenty of activities to create a repository, storing content and promote findings encourage cultural change required. Besides, how want the best care possible if digital preservation is not embedded as part of the repository worked and there was not much

The first context in digital preservation is preserving context within digital preservation. The second context is capturing context with content that is a common problem various communities. In the preserving context within digital preservation systems is through the implementation and preservation digital ontology that can be used to structure, semantic, space and the time exist in the record. The usage of digital ontology is proposed to create a network of information representation. There are six types of relationship characteristics of digital information in the environment. The first is that the rule-based logic can be interpreted with the help of the system. The second dimension of time can be used to understand and interpret the information. The third is that the space used to understand and interpret the information. The next is the procedure that can help to students the workflow associated with an information. The fifth and sixth are the procedures that help to understand the procedure or workflow-related information and functions that represent the result of applying an action or transformation. Other than that, in the capturing context with content a common problem various communities is the challenges inherent in the community is to capture and record the context for better access. Among the library classification and subject indexing schemes, capture and representation of context has become a field of
