Research Data Things 11/23 - What's My Metadata Schema?



Getting Started


Unfortunately, in the rush to publish the metadata for datasets are often an afterthought. Until now, the focus has always been on the article being published. Data sharing and providing good metadata is still an unknown for many so is often done last-minute or after the fact (oh that's right I'm obliged to share my data, better bung it together and get it in the repository).

Education and familiarity will help, but so too will experiencing the challenge of trying to use someone else's metadata encourage researchers to think more carefully about their own data. Many academic libraries now provide consulting services on research data management, curation and metadata. Promotion of these services is important in getting the message out.


Another inhibiting factor may be the constraints of turnkey institutional repository systems which do not provide fully customisable metadata fields. Libraries may be waiting on the provider's support to address missing fields. The challenge for the repository provider is that they are offering a solution that needs to fit multiple institutions/disciplines where the metadata has different flavours. Numerous schema exist and in most institutions there are numerous disciplines.

Challenge Me



Option 2 seemed too easy since I have worked with xml files for years including one yucky ANZAC day holiday where I had to edit an ERA submission file due to a business rule fault in the research data system we were using.

So... Option 1. Using ANZmet lite.


  • First problem was an error message about ANZmet not being able to reach a website. 
  • No tip for the additional (optional) citation field 
  • No advice on which order to enter the author's name eg. Lastname, Firstname 

It made it relatively easy to produce a valid record.
