A mind map of data stewardship topics. I started collecting these topics in October 2013. It is continuously being updated through accidental encounters as well as deliberate interviews with experts. The version of July 2019 updates the top level topics to correspond to a more standard data life cycle; this did not exist when the effort was started in 2013. Only few of the actual branches have changed since the first uploaded version, but many branches have moved to a new home. Many of the topics collected here are presented as a hierarchical set of questions for Data Management Planning in the Data Stewardship Wizard (https://ds-wizard.org/). The information in the mind map is available in a formalized form (a set of JSON data files) from an open github repository in the Data Stewardship Wizard repository (look for the "knowledge model"). The original document is edited in the "MindNode" software, and at irregular intervals a view is uploaded to the MindNode cloud: https://my.mindnode.com/gsJTmqsvsecXzKVw2KZtNQMGyFPKqabQ3pNcXdCH
