HOW WE CURATE DATA
STANDARDS & TOOLS
OUR METADATA STANDARDS / QUDEX
The Qualitative Data Exchange Schema (QuDEx) enables discovery, locating, retrieving and citing complex qualitative data collections in context.
The schema is complementary to DDI and enables:
- highly structured and consistently marked-up data
- rich descriptive metadata for files e.g. interview characteristics, interview setting, type of object
- logical links between data objects: text to related audio, images, and other research outputs
- preserves references to annotations performed on data
- common metadata elements that enable federated catalogues across providers and borders
The standard is maintained by the UK Data Archive, University of Essex and the project overview and outputs can be accessed from the DExT site. The UK Data service QualiBank uses the schema, along wth TEI and DDI 2.5.
In late 2007, version 2.0 of the QuDEx draft schema was made
available for testing. Some critical amendments have been made for
Version 3.0, following on from feedback and XML consultants from
the Open Data Fundation.
The Version 3.01 draft schema, accompanying documentation and XML
instance files are all available.
