WG 3 will make a systematic review of recent and new concepts and standards for data management, including aspects of content definition (vocabularies, thesauri, languages) and technical ones (for integration and interoperability). WG3 will exchange experience on all these matters and identify technical shortcomings and knowledge gaps. These gaps might lie in the administrative and legal area (e. g. management of ABS relevant data), in the technical context (management of highly structured complex data, data streams and big data) and in the interoperability with the changing landscape of analysis tools, mobile apps and portals. Also, the challenges in the area of data curation and quality management are growing, as well as in the organisation of multimedia and vector objects together with their structured technical and content metadata. WG3 will analyse the landscape and distribute this knowledge with best- practice papers and documentations. The results will directly feed the DiSSCo Research Infrastructure proposal on the natural history museums and collections.
