The Publishing Data Interest Group of the Research Data Alliance brings together all stakeholders involved in publishing research data. Its goal is to address the implementation of workflows for publishing data and therefore help establish appropriate supporting infrastructure.
A couple of days ago the Interest Group issued a proposal for four new Working Groups under the title "Data Publishing 2020" on the following topics:
- Cost Recovery for Data Centres
- Data Publication Services
Note also the ongoing discussion in the comment section on the question what is meant by "data" and "publishing data".
