Packaging research data for discovery, distribution and reuse is a key concern for repositories; research data sets almost always consist of more that one kind of file and it is a challenge for repository managers to make data available in appropriate formats. This two-part workshop will cover the state of the art in research data packaging - building on the outcomes from a successful and well attended workshop on Research Objects at eScience 2018 in Amsterdam but with a more tutorial approach. The morning part of the workshop will cover an introduction to data packaging and metadata for data discovery via search engines with practical advice about available tooling and examples of repositories using them. The afternoon will be an interactive session which will allow participants to get advice, discuss further work needed in this space and convey their requirements to leaders in the data packaging and repository technology space.
