The Colectica Curation Tools allow data archives to leverage the DDI standard for data documentation and to structure the curation workflow. The platform combines several open source off-the-shelf components with a new, web-based data pipeline application, and enables a seamless framework for collecting, processing, archiving, and publishing data. The platform enables open access to data resources that have been fully reviewed and enhanced for long term usability and analysis.
Ingest Studies and Files¶
Depositors use the web application to upload files and provide basic information about their research.
Every catalog record is assigned a curator. The curator is responsible for reviewing the record and all files. This review may include several checks, which are assisted by the software.
- Find and remove confidential or identifiable information
- Find missing labels in data files and add appropriate metadata
- Identify potential data errors
- Confirm reported observation counts against the data
- Confirm that source code succesfully builds and executes
- Confirm that source code replicates reported results
Publication and Archiving¶
Once curation is complete and a catalog record is approved for publication, the system automatically performs several actions to aid in preservation and publication.
- Create preservation formats for proprietary data files.
- Request persistent identifiers from the configured Handle service and store them with the metadata.
- Create checksums for each file and store them with the metadata.
- Create DDI metadata for all files and the catalog record itself.
- Create an archive package and place it in the configured archive ingest location.
- Mark the catalog record as published.
