Metadata Quality

How complete the metadata of the portal's theses and dissertations is, element by element, and how much of it comes from the institutions' own repositories. Measured against the ETD-MS 1.1 metadata standard for theses and dissertations used by NDLTD, plus faculty, department and full text.

In the repository element — supplied by the institution's repository in the proper metadata element Elsewhere in the repository — supplied by the repository, but only in collection names or free text Filled by the portal — read from the PDF by the portal's models, or corrected by the portal team Missing — no value

64.9%ETD-MS compliance at source: the mean share of the 12 ETD-MS elements that repositories supply in the proper metadata element
80.3%complete in the portal: the mean share of all 15 elements with a value, after the portal fills gaps from the full text

About these figures

  • Computed after every nightly harvest; last computed November 1, 2026, 16:09 (Lusaka time). Download: CSV · JSON.
  • "At source" counts only values the repository supplies in the proper metadata element. Values the portal reads from collection names or free text, or fills from the PDF (shown with a "derived" badge on record pages), make the portal more complete but do not help other services that harvest the repositories directly.
  • Institutions that want to improve their metadata can contact datalab@unza.zm; the guide for institutions lists the recommended fields.
