In this paper we present datelife, a service implemented via an R package and a web site (http://www.datelife.org/) for efficient reuse, summary and reanalysis of published data on lineage divergence times.
Phylogenetic knowledge is of great importance for research and education. Yet, it remians mostly unavailable for the non-specialist and the general public. In this paper, we report a publicly accessible system for on-the-fly delivery of phylogenetic knowledge that consists of a web portal that implements 3 types of workflows to obtain species phylogenies (scaled by geologic time and decorated with thumbnail images); 19 underlying web services accessible via a common registry; and toolbox code in R and Python so that others can create applications that leverage these services.
