Keynote Speaker

Any type of digital information that describes resources or supports their discovery and is produced or curated by libraries is defined as Library Data. Indicatively such information could be datasets (e.g. catalogues, bibliographies), vocabularies and metadata elements (e.g. elements of MODS or MADS). Nowadays these data are published as Linked Data and thus are called Library Linked Data (LLD). LLD exploit the benefits of the Web technologies and provide to their users improved capabilities for discovering library and non-library information resources from other trusted sources. Moreover, the cataloguing paradigm changes from top-down, where libraries produce records for their material, to bottom-up, where resources can be described in collaboration with libraries and also linked to data contributed by other communities.
There is a number of initiatives regarding the exposure of LLD into the Web. Depending on the initiative’s objectives, the scope and the intended use of the data, each initiative developed its own interpretation of how Library Data may be integrated into the semantic web, providing its own conceptual model, such as FRBR, BIBFRAME and EDM. However, these different views cause interoperability problems and prevent data integration.
Moving towards a data driven world, the quality of data is critical and affects the outcome of all data management related tasks. Metadata quality also affects information integration and retrieval since they are metadata driven, while its evaluation should consider their interpretation as determined by the conceptual model in use. This presentation aims to interlink the concepts of LLD interoperability and data quality. It reveals LLD interoperability issues providing cases of bibliographic patterns that are represented differently by particular library data conceptual models. Furthermore, it overviews results from ongoing research regarding the assurance of the quality of Library Data during their integration, when instances of one library conceptual model are transformed to those of another.
