The Research On The Source Software Applied In The Digital Library

The digital library is an important tendency for construction of the modern library, therefore, along with movement of the source software in recent years, digital library also more operates the source software, therefore this article takes the source code of the digital library as a standpoint, first introduced the origin of the source software. the source software come from its predecessor the free software which is famous, then defined the concept of the source software, the basic characteristic of the source software, the basic classification of the source software as well as the influence of the source software to the digital library. The source software in the digital library divides into two forms, one is the source software tool, which develops the digital library system, for example: Database and so on; Two is the source software system, which is a software system which is generally developed by large-scale libraries. This software system has some kind of function formation, which may be used directly by other digital library, also may be carried on the re-development; Next, this article in the investigation and study analysis foundation, introduce the overseas five representative digital library system comparisons. These five the source software include three open source database management system MySQL, which is used by the majority databases to develop and the management at present; the source database server Apache, and in the source database server it mainly introduces Tomcat; the source language - - Java, Java language is the present quite popular object-oriented language, and its simple grammar structure is advantageous for people's study, moreover it may realize compilation and the movement of the different software and hardware platform. The permit type of the source software to be numerous and diverse, the content and the scope of the different permit stipulation use are various, and each kind the source software has one kind of permit. Therefore these three kinds above also has own permit, and they all follow the GPL permit, and the source software system also use the GPL permit developed by them. The two source software system is the Eprints and the Avanti. The Eprints mainly memories numeral resource, and its application had already spread all of the world at present, and also is in unceasing development of new edition; The Avanti is quite nimble, exquisitely, but the function is complete. The surface of retrieval contact is succinct, and is first choice of the source software to the digital library. At the same time, this article summarized two superiority from the new angle of view to apply the source software in the construction of the digital library; Finally, in view of the present domestic and foreign digital library the condition, this article deeply analyzed the questions of application of the source software existed Our Library, and obtained the corresponding solution countermeasure from proposes of the question essence. this article proposed questions in the application of the source software from the angle of the source, providing the rationale of selecting the source software, thus it causes library itself to grasp the core technologies, and establish the main body status in the network information environment meanly for the information center, transforming new pattern adaptation for development of the need, so it completes the new mission of library under the digital environment.
