Public Data Repositories

Public data repositories are one option to publish your research data. They usually focus on the data – as opposed to other research outputs such as manuscripts. Data repositories assign persistent identifiers (e.g. a DOI) to your dataset and by that comply with requirements of most publication journals.
We differentiate between domain-specific and general-purpose repositories.

Domain-specific data repositories are well-established in a domain or community specialized on a certain data type. They frequently co-develop or foster compliance with metadata standards (see metadata) and oftentimes curate data. Data deposition at these repositories is recommended.
The following table lists examples of relevant endpoint repositories (ER) for data produced by DataPLANT participants. Check the links below for additional repositories.

In cases where no suitable domain-specific repository exists, general-purpose repositories are an option to publicly deposit research data and receive a PID. A benefit of general-purpose repositories is that they allow deposition of virtually any data type. Also research data packages with mixes of data types and computational workflows can be deposited, which aligns well with typical plant science investigations. However, since these repositories can only foster compliance with metadata standards at a very generic level (e.g. bibliographic or technical, see metadata), they limit the capacity for FAIR reuse of data.

Examples for general-purpose repositories include

• Zenodo https://zenodo.org,
• DRYAD https://datadryad.org/, and
• FigShare https://figshare.com.

The following resources provide good starting points to seek a suitable repository for your research data.

Depositing research data at a public data repository can be tedious. Especially the domain-specific repositories require compliance with specific data submission routines (a) in terms of format and content and (b) for both "raw data" and "metadata". Only data types relevant for the respective domain are accepted and need to be provided in proper data formats. In order to guarantee that the information required to properly describe the data is present, they require adherence to domain-specific metadata standards, represented in the proper format and oftentimes require the use of controlled vocabularies and ontologies. And finally the mere technicalities of how to collect and submit the (meta)data varies greatly between repositories, ranging from the use of pure upload via file transfers (e.g. FTP), APIs, online web forms or specialized software requiring local installation. The large repository providers invest a lot to harmonize their formats and submission routines. Still, there is a long way to go and we are currently far away from the unified way where "If you know one, you know them all."
