The RADAR User Advisory Board prioritized the option to retroactively correct descriptive metadata as an important new RADAR functionality. This option is available for the first time with RADAR software version v 1.11 that was released on December 09, 2021.
This enables users to retroactively correct the metadata annotation of a dataset that has already been archived or published; for example, to correct typos or to add missing information. Publishers also frequently request the previously published research dataset prior to journal publication. This means that the link from the dataset to the article in the RADAR metadata can only be made at a later time.
When the metadata is corrected, only the metadata catalog and the description on the RADAR landing page are updated. RADAR does not create a new dataset, nor does the system assign a new persistent identifier (e.g., DOI). The research dataset (.tar-file) stored in the data archives remains unchanged, as does the technical metadata including checksum (MD5).
A note on the RADAR landing page transparently informs data users about the metadata correction. The updated descriptive metadata is displayed there and is available for download (.xml). RADAR submits the metadata corrections of published datasets to DataCite and also offers them for harvesting via our OAI provider.
Metadata can be flexibly corrected at all levels of a RADAR dataset. In addition to the description of the dataset, the annotations of files and directories contained therein can also be corrected or supplemented.
The new feature builds on the proven RADAR roles and rights concept for data archiving and publication. Both subcurators and curators can correct metadata, but only curators may give final approval of the correction. All updated metadata is checked against the RADAR metadata schema, as usual.
Please note: Information contained in the metadata fields "Persistent Identifier" and "Rights Statement" cannot be corrected. If there is a need for correction here, you must create a new dataset at the current point of time. Versioning to correct or update the actual research data is already in planning.
We have also further improved the accessibility of the RADAR software with this release. After our BITV test (self-assessment in 92 test steps) had previously focused on the publicly available pages of the RADAR portal, this time it was, among other things, also extended to the form pages for creating datasets and to the metadata editor. The RADAR web application is now largely BITV 2.0 compliant. The newly revised accessibility statement can be found here.
The v 1.11 release is completed by further UX improvements. From now on, for example, you can edit datasets in "in process" status more intuitively and add or delete individual files and directories more easily.
We hope our latest enhancements will improve the user-friendliness of RADAR!
