QuDEx

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, and the project overview and outputs can be accessed from the DExT site.

The Archive's use of QuDex: The UK Data Service's QualiBank uses the schema, along with the TEI and DDI Codebook.
