This release brings new features, enhancements, and bug fixes to Dataverse. Thank you to all of the community members who contributed code, suggestions, bug reports, and other assistance across the project.
Auxiliary Files (Experimental)
Auxiliary files can now be added to datafiles and accessed using new experimental API endpoints. These endpoints allow additional, non-Dataverse generated metadata to be added alongside datafiles in dataverse.
The support for auxiliary files in Dataverse is being driven by integration with the [Open Differential Privacy (DP) Project](https://opendp.io) and is designed to support the deposit and retrieval of differentially private metadata, but the endpoints are not specific to differential privacy use cases.
Additional Banner Functionality
Banners in Dataverse can now be set to allow dismissal by a logged in user. Previously, banners would persist until they were removed by an administrator. This allows administrators to more easily communicate one-time messages to users.
File Tags Searchable from Advanced Search and Dataset Search
File tags ("Documentation", "Data", "Code", etc.) now appear on the Advanced Search page.
Performing a search for files on the dataset page now includes file tags. Previously, only file name and file description were searched.
Easier Configuration of Database Connections
Previously, the configuration of the database connections has been quite static and not very easy to update. This has been an issue especially for cloud and container usage. Using new technologies provided by the move to Payara, you can now more easily configure the connection to your PostgreSQL DB.
Using MicroProfile Config API (Issue #7000, Issue #7418), you can much more easily specify configuration
details. For an overview of supported options, please see the Installation Guide.
Note that some settings have been moved from domain.xml to code, such as min and max pool size.
Major Use Cases
Newly-supported use cases in this release include:
- Users can use an API to add auxiliary files to files in order to provide metadata representations for specific tools or integrations (Issue #7275, PR #7350)
- Administrators can use a new API to manage banner messages and take advantage of new banner display options (Issue #7263, PR #7434)
- Users replacing files will now have their files renamed when a file name conflict exists, making the behavior consistent with upload and edit (Issue #7335, PR #7336)
- Users will now be able to search on file tags on the advanced search and dataset pages (Issue #7194, PR #7385)
