I am a PhD student and am one step away from graduating. I have created a dataset in 3D microscopy vision, particularly 3D surface reconstruction from scanning electron microscope images, and the work has been already published in a highly respected journal. I would like to share the dataset with the research community to draw attention and possibly evaluate the contribution(s).
I am wondering what are the typical channels that scholars use to share datasets?
You could just host the data on your own university homepage but I would not encourage this. You can not guarantee stable a URL or long-term support. A website of your institute or a project website would be a bit better but still, long term support is not guaranteed.
You may want to check out Harvard Dataverse at https://dataverse.harvard.edu/. It seems to cover many different fields and provides dois (i.e. permanent links) which make the dataset citable.
I've would prefer ResearchGate to make datasets publicly available in addition to your publications. ResearchGate also has the option to generate a DOI for the same. This would hence also increase the visibility of your research.
You have also Kaggle.com where you can publish your datasets. It allows users to find and publish data sets in a web-based data-science platform. On an early post you can find more debate regarding a more specific question to it.
