Digital library objects can be quite complex, with a lot of metadata, possibly in many languages, and data in different digital forms. In order to reduce the overhead of adding, or modifying objects to a digital library we made tools that simplify the operation of submitting new objects, so that the object creators can directly send them to the library, where appropriate. Moreover, our tools simplify the numerous actions that a non computer-expert librarian may have to perform to maintain such a library.These tools provide an easy way to input or modify the metadata describing a submission and also to upload the digital documents, as well as inspect, commit or modify new submissions or old objects. They also comply with multilingual and heterogeneous collection extensions, where the metadata fields describing each collections may be different. Finally, to be able to be widely used and to suit most needs, these tools are fully configurable (including paths, languages, fields per collection or even messages, colors etc) while at the same time their minimal configuration is very simple, especially when used with DIENËT ([2]), by reading directly the DIENËT configuration information. We made these tools easy to install and at the same time powerful and configurable. The tools, have matured through requirements and comments of many users and are already in use in the digital library of the University f Crete, with great acceptance. System security is enforced mainly through web-server access control mechanisms. For more information, see [1].
The tools are normally sharing con guration les with DIENST, so that no redundant con guration information need be given. Nevertheless, they do not depend on the running of a DIENST server, and can be used for submission for other digital library systems, with the appropriate con guration. They provide functionality that will cover even rare requirements and oer many optional features, through con guration choices, depending on the sophistication of the environment.
