ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a method for creating digitized archives on removable mass storage media used in digital libraries, and to a digital archive server for loading digitized archives on removable mass storage media into databases of digital libraries.
BACKGROUND OF THE INVENTION
A digital library is an important part of the “information highway”. In general, a digital library includes several components such as a network, a database server, mass storage, and user interfaces. Usually, an archive material is entered into a digital library by the following steps:
1. digitizing the archive material by manual entering, photoelectric recognition, electronic scanning, digital sound and image recording, etc.;
2. storing the digitized archive material into a mass storage pool of the digital library; and
3. extracting record items associated with the archive material and physical or logical addresses of the digitized archive material on the mass storage media of the digital library, and loading the record items and physical or logical addresses into databases of the digital library.
Once an archive has been entered into a digital library, readers or users will be able to obtain required materials by accessing the digital library via the computer terminals connected to the network.
Nowadays, in the “information highway” environment, information is exchanged mainly by means of removable mass storage media used as physical carriers, apart from direct transmission using networks. At the present time, CD-ROM is one of the most important media. In a digital library, text, photographs, movies, music and other archive materials are usually digitized and stored on CD-ROMs, forming CD-ROM archives. However, CD-ROM archives have the following problems:
1. The formats in which the archives are recorded on CD-ROMs are inconsistent with each other;
2. On CD-ROMs there is no index information for each archive; and
3. CD-ROM archives have to be loaded into database management systems of electronic digital libraries manually.
As a result, a large quantity of manpower, material resources and time will be wasted while CD-ROM archives are loaded into databases of digital libraries. Also, CD-ROM archives prepared for one particular digital library can be used only in that system. If CD-ROM archives prepared specially for one digital library are to be used in another digital library, these CD-ROM archives have to be loaded into databases manually. Thus, the distribution and exchange of CD-ROM archives are greatly hindered.
SUMMARY OF THE INVENTION
The first objective of the present invention is to provide a method for creating digitized archives on removable mass storage media.
The second objective of the present invention is to provide a digital archive server for loading digitized archives on removable mass storage media into databases of a digital library.
For achieving the first objective, the present invention provides a method for creating digitized archives on removable mass storage media, comprising the steps of: digitizing archives into digitized archives; extracting record information of the archives; and storing the digitized archives and the record information onto removable mass storage media.
For achieving the second objective, the present invention provides a digital archive server for loading digitized archives from removable mass storage media into databases of digital libraries. The digital archive server comprises:
means for reading record information stored on the removable mass storage media; and
means for loading said record information into the database tables of the digital library.
According to the method of the present invention, the formats in which digitized archives are recorded on removable mass storage media can be unified so that digitized archives on removable mass storage media can be exchanged among digital libraries. With the archive server of the present invention in digital libraries, digitized archives on removable mass storage media can be automatically loaded into database management systems of digital libraries, thus greatly reducing the required manpower, material resources and time.
Other advantages and features of the present invention will be more apparent through the following description in detail with reference to the accompanied drawings.
