ORDO is best used when no other repository suits your needs. Many research councils require research data from their funded projects to be stored in one of their own data centres and provide specialist help with data preparation; journal publishers often require submitting authors to store supporting research data in specific data stores. Publishing research data in discipline specific repositories can help surface your research within a particular community. Where to share your data provides more help on choosing repositories.
Once you have selected which data to share, you need to ensure their long-term value is maintained. You can do this by providing detailed metadata, following discipline standards where required; and using open file formats wherever possible. Preparing data for sharing provides more help on data preparation prior to upload.
