Although there is an increasing need for data in ecological studies, many datasets are still lost or not sufficiently visible due to a lack of appropriate data archives. With the West African Data and Metadata Repository, we present a secure long-term archive for a data-poor region allowing detailed documentation by metadata following the EML standard and giving data holders the opportunity to define levels of data access and conditions of use. This article gives an overview of structure, functions and content. The repository is online at the URL http://westafricandata.senckenberg.de.

In this paper we outline the process of revising data access categories for research data sets in GESIS – a large European social science data archive based in Germany. The challenge is to create a minimal set of workable access conditions that cope with a) facilitating as “open as possible, closed as necessary” expectations for data reuse; b) map on to existing legacy access categories and conditions in a data archive. The paper covers the work done in gathering data on data access categories used by data archives in their existing data catalogues, the choices offered to depositors of data in their user agreements, and work done by other data reuse platforms in categorising access to their data. Finally, we talk through the process of refining a minimal set of data access conditions for the GESIS data archive.

No systematic approach has yet been adopted to reliably reference and provide access to digital biodiversity datasets. Based on accumulated evidence, we argue that location-based identifiers such as URLs are not sufficient to ensure long-term data access. We introduce a method that uses dedicated data observatories to evaluate long-term URL reliability.From March 2019 through May 2020, we took periodic inventories of the data provided to major biodiversity aggregators, including GBIF, iDigBio, DataONE, and BHL by accessing the URL-based dataset references from which the aggregators retrieve data. Over the period of observation, we found that, for the URL-based dataset references available in each of the aggregators' data provider registries, 5% to 70% of URLs were intermittently or consistently unresponsive, 0% to 66% produced unstable content, and 20% to 75% became either unresponsive or unstable.We propose the use of cryptographic hashing to generate content-based identifiers that can reliably reference datasets. We show that content-based identifiers facilitate decentralized archival and reliable distribution of biodiversity datasets to enable long-term accessibility of the referenced datasets.

ABSTRACT Computational reproducibility, or the ability to reproduce analytic results of a scientific study on the basis of publicly available code and data, is a shared goal of many researchers, journals, and scientific communities. Researchers in many disciplines including political science have made strides toward realizing that goal. A new challenge, however, has arisen. Code too often becomes obsolete within only a few years. We document this problem with a random sample of studies posted to the Institution for Social and Policy Studies (ISPS) Data Archive; we encountered nontrivial errors in seven of 20 studies. In line with similar proposals for the long-term maintenance of data and commercial software, we propose that researchers dedicated to computational reproducibility should have a plan in place for “active maintenance” of their analysis code. We offer concrete suggestions for how data archives, journals, and research communities could encourage and reward the active maintenance of scientific code and data.

Antislavery and Imperialism: The British Suppression of the Slave Trade and the Opening of Fernando Po, 1827–1829

AbstractThis article chronicles the construction of the first permanent foreign settlement on the West African island of Fernando Po (today called Bioko) as part of the British effort to suppress the slave trade in the 1820s. The settlement ended centuries of relative isolation by the indigenous Bubi who hitherto had successfully navigated between occasional trade with outsiders and repelling slave traders. Although British plans ultimately failed, the settlement remained, as did a large portion of the settlers. This article argues that the disruptive power of suppression created the conditions for a colonial shift toward integration of the island into the larger Euro–West African world. While the settlement's influence grew in the short term through its successful leveraging of economic and military resources, it was the landing of liberated slaves that would have the greatest long-term significance, and highlights the (often unintentional) connection between antislavery and imperialism.
