There will be a workshop during the next open science conference June 28 on hardware publication , see Workshop at the open science conference, there is a 50€ fee to participate in the online conference. We have some money in the project to cover that fee if you would like to participate (please write us).
We have been collecting a lot of use case from specific OH projects, and will now present a putative hardware publication platform idea to scholarly communication experts. We hope to get feedback about what could actually be implemented and how.
We will have more details about our plan mid June and ask for your feedback by then ;).
