A common goal for many institutes and universities focuses on digitizing entire collections. Hundreds, thousands of individual books are stored in a detailed version within digitized libraries. What is an interesting aspect of all these books is that they contain written text as well as graphics. They can be represented in the format of music metadata, as part of music collections, or many other formats such as scholarly articles, citations and bibliographies. For analyzing various types of books, the Linked Open Data(LOD) services have been developed.

Linked Open Data describes an option of publishing structured data in such a way that it can be interlinked, and consequently become more useful for both analyzing the un-digitized version and working with the digitized resources. This means that the standard web technologies such as HTTP, RDF and URI(s) are extended from pages readable only by humans into a collection of data that can be read automatically by computers. Being able to link information in this manner will enhance discoverability and facilitate research.

The semantic web aims to convert the current web, dominated by unstructured documents, into a “web of data”, with common data formats, by encouraging the utilization of semantic content into the web pages. Experimentation with Linked Open Data provides ways of connecting different elements such as music metadata, historical, biographical, geospatial data, articles, citations, themes and topics, multi-lingual texts, different metadata resources, annotations, mixed text and graphic resources. This will eventually lead to the improvement of search capabilities and a better user experience and usage of the Internet.

One of the applications that uses Linked Open Data is Bibliopedia. Currently a working prototype, Bibliopedia’s aim is to search resources about various articles and books. Then, it will examine them for citations and present the results in a publicly accessible database by placing the metadata about scholarly literature in link data format, open for future innovations. In this way, Bibliopedia will ease the discovery of new scholarly works and the relationships between them, by checking the bibliographic links and references. Consequently, scholarly literature can be browsed back, but also forward in time. The Bibliopedia system can thus become a powerful tool for research by incorporating all the benefits of technologies like data aggregation, collaboration and social media.

The semantic web technologies have also been successfully used in music collections, having various approaches of linking data. The Contemporary Music Centre aims to use such technologies in order to obtain a fully digitized archive in which music information, compositions and materials metadata, music-related data as well as non-musical content are all interlinked in digital libraries.

Another application of Linked Open Data services focuses on digitizing emblem resources for better research purposes. Emblems refer to a mix of texts and graphics, which are multi-lingual and can be sorted by different themes and topics such as religious, political and social contexts. Iconclass as a language thesaurus has proven its utility for emblem literature by facilitating multi-lingual research. Iconclass supports RDF XML for displaying metadata, such that research scholars can find related emblems.

Linked Open Data services lead to a faster discovery and better search results by linking context about emblems, authors, places, music collections, articles and other attributes. In this manner scholars can fully benefit of the existing information.
