When Libris, the Swedish university and research libraries’ search service for books, dissertations, periodicals and journals, printed music et cetera, is developing new system architecture and a new cataloguing tool, the National Library in Sweden is developing a format-independent system that uses related information elements instead of posts, and incorporates the basic principles that constitute the web.
It is a linked data format that provides a way to collaborate at Web scale. This means that all posts in the catalogue will be represented as generic linked metadata and will be compatible with the context of the whole Semantic Web.
When all of the MARC metadata has been translated and converted into JSONLD, and all the data has been re-mapped, the bibliographic data can be described and presented in a completely new way.
The new Libris XL search service will go live at the beginning of 2015. In many ways, this development is pioneering and its progress is headed up by Sweden and its national library.
Niklas Lindström, a leading expert on linked data, is working with the Libris XL project at the National Library of Sweden.
“The primary motivation for us to use linked data is to enable the means of reducing repetition and duplication. This can be done by describing things succinctly, using widely-known properties and classes whenever possible. Based on that, by linking to related things described similarly, we can avoid repeating their descriptions. This enables us to combine specific vocabularies and external data, which makes our cataloguing work part of a worldwide web endeavour to build common machine-processable descriptions and to interconnect shared, local data,” he says.
The new structure of the catalogue will make it possible to adapt it to the new RDA (Resource Description and Access) cataloguing practice being introduced in Sweden. RDA describes data elements and the relations between them, and does not use any specific format because its goal is to make the data flexible so that it can be used everywhere and not only within libraries.
