Linked Data + Drupal for Oceanographic data management
•
1 like•1,178 views
For ocean science researchers, the success of data discovery revolves around the capability to ask complex questions of data centers like BCO-DMO. Our ability to accurately respond depends on our system's capability to understand the question, interpret its relevancy to what we know, and return those results in a way a human can digest. As the needs for responding to the grand challenges of science become more interdisciplinary, data discovery will become more dependent on information from a variety of sources to enable researchers to reliably access the data they need. To do this effectively, all data and their metadata require context, cooperation and semantic interoperability. This talk explores the current landscape of data discovery, the questions researchers ask of our software, how bad our software is at responding, and how Linked Data is a viable solution for improving those responses.
