By Mingfang Wu

The demand for better reproducibility of research results is growing. More and more data is becoming available online. In some cases, the datasets have become so large that downloading the data is no longer feasible. Data can also be offered through web services and accessed on demand.

RDA/TDWG Attribution Metadata Working Group: Final Recommendations

By Anne Thessen

Research collections are an important tool for understanding the Earth, its systems, and human interaction. Despite the importance of collections, many are not maintained or curated as thoroughly as they should. Part of the reason for this is the lack of professional reward for curation, maintenance, or collection. To address this gap in attribution metadata, this Working Group recommends the use of PROV entities and properties to link people (Agent), the curatorial actions they perform (Activity), and the digital or physical objects they are curating (Entity). Assigning a Role to an Agent is optional. These recommendations are discussed in the context of the RDA and existing standards. A separate technical document gives specific examples of three use cases as RDF Turtle representations and diagrams.

Research Data Repository Interoperability WG Final Recommendations

By Thomas Jejkal

The goal of the RDA Research Data Repository Interoperability WG (RDRIWG) was to achieve consensus on an adoptable approach to facilitating research data repository interoperability for a defined set of initial use cases. The following document presents final recommendations the members of the RDRIWG have agreed on. It describes a general exchange format based on the well-known BagIt specification complemented with BagIt Profiles, another specification defining how to describe the internal structure of BagIt-based packages. In order to achieve a basic level of interoperability with regard to the content of such exchange packages, the WG members have agreed on recommending to include DataCite metadata in each package. The presented recommendations document describes the exchange format itself together with adoption guidelines and information about related efforts. In addition, early adoptions are publicly available at GitHub and referenced within the document.
