Library Systems
A library system provides an integrated set of services for capturing, cataloging, storing, searching, protecting, and retrieving information about various publications of interest.
Digital libraries are full-text databases that replicate, in digital media, many of the functions of traditional libraries. They tend to contain a purposefully selected collection of texts plus various means of access to these texts.
JeromeDL
JeromeDL is a Social Semantic Digital Library. As a digital library, it allows institutions to easily publish documents on the Web. It supports a variety of document formats and allows to store and query a rich bibliographic description of each document.
To find relevant documents in JeromeDL users can use searching and browsing features. Whole documents content can be searched through, as well as single fields of the documents description, like author or publish year. Users can also find documents by browsing content of subject categories and keywords.
With JeromeDL's social and semantic services every library user can bookmark interesting books, articles or other materials in semantically annotated directories. Users can allow others to see their bookmarks and annotations and share their knowledge within a social network. JeromeDL can also treat a single library resource as a blog post. Users can comment the content of the resource and reply to others' comments and this way create new knowledge.
JeromeDLs middleware implements features like viewing resources, searching and browsing, users' profile management (based on FOAF) and resources management. The description and content of the resources, e.g., the fulltext index of the resource's content, MARC21 and BibTeX bibliographic descriptions and semantic description according to the Jerome ontology are held in several stores. Apart from the textual resources the JeromeDL system has been designed to also handle the collections of scans of old books and other binary resources like e.g. Macromedia Flash presentations. A communication link to the outside world enables searching in a network of digital libraries.
The database content of the JeromeDL system is rendered in XHTML following an HTTP request. To administrate the content of the database and to describe the resources in the database a stand-alone application, JeromeAdmin, is utilized. JeromeAdmin communicates with the main system through the RMI (Remote Method Invocation) protocol. The content of the JeromeDL database can be searched not only through web pages of the digital library but also from the other digital libraries and other web applications through a special web services interface based on the Extensible Library Protocol (ELP).
