DATA CURATION PROCEDURES
Data acquired for the UK Data Service collection undergo rigorous and comprehensive curation prior to publishing and release. This ensures that data, documentation and metadata are processed and published to the highest standard possible, both for ease of use in secondary analysis and for archival preservation.
The curation procedures carried out depend on the individual nature of each dataset and document, but as a general guide the following tasks are always undertaken:
- Disclosure review - if data confidentiality issues are identified, they are resolved in consultation with the data depositor;
- Data are checked for consistency and accuracy – for example undocumented/out-of-range codes;
- Variable and value label metadata are checked and enhancements undertaken as necessary;
- Multiple data and documentation formats may be generated for dissemination and preservation;
- A catalogue metadata record is generated and a Digital Object Identifier (DOI) is assigned to the study where appropriate.
- Where the data are made available for online analysis, in addition to the checks above, question text may be added alongside variables and other enhancements made.
DATA AND DOCUMENTATION NOTES
For the second edition (March 2008), a new version of the data file was deposited, with the family serial number variable (famsrno) replaced by a new serial number variable, mcsid (MCS Research Serial Number). The documentation remains unchanged.
