Metadata strategy

October 6, 2010

The University of Southampton data management project has proposed a three-level metadata strategy, see their blog entry “Metadata strategy“:

  1. Project
  2. Discipline
  3. Core

Tardis is based on the Core Scientific Metadata model (CSMD) developed within the Science & Technology Facilities Council (STFC).  One metadata hierarchy they’ve adopted is (turned upside down to match Southampton’s):

  1. Science Specific
  2. Instrument Specific
  3. Core

(This reminds me of Robert Pirsig’s Intellectual Scalpel)

We’re extending Tardis for use within the Australian Synchrotron and ANSTO, where the STFC model is more appropriate.  However, institutional use of Tardis may also be project based.

Tardis supports configurable schemas (parameter sets) at  the experiment, dataset and datafile level.  Appropriate use of the configurable schema should allow us to handle both models, or a combined model.

Using a Core Scientific Metadata Model in Large-Scale Facilities

July 22, 2010

Thanks to the UKOLN News Feed for pointing to the International Journal of Digital Curation Vol 5., No 1. It contains a paper titled Using a Core Scientific Metadata Model in Large-Scale Facilities.  The paper provides a good overview of the CSMD schema, which is “a model for the representation of scientific study metadata developed within the Science & Technology Facilities Council (STFC) to represent the data generated from scientific facilities”.
