The University of Southampton data management project has proposed a three-level metadata strategy, see their blog entry “Metadata strategy“:
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):
- Science Specific
- Instrument Specific
(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.
