This document discusses Scratchpad virtual research environments for sharing, linking, and publishing biodiversity data. It notes that most biodiversity data is currently not in digital, openly accessible, or linked formats. Scratchpads are introduced as hosted websites for biodiversity data, which allow researchers to create virtual research platforms, publish data openly and flexibly. The document outlines the types of biodiversity data that can be incorporated into Scratchpads, including taxon pages, maps, images, literature, and matrices. It also summarizes the goals and funding of the ViBRANT project, which aims to develop a federated network of biodiversity informatics infrastructures through Scratchpads and other virtual research environments.
