[Ant Beck]

Hi All,

We (dartportal.leeds.ac.uk) created a structured automated metadata 
creation system to handle our data ingest of thousands of stuff 
(different formats, datasets and sensors). There is definitely a need 
for this, especialy for those who may want to bulk upload archives.

Our code is not generic - I'm happy to share it if you would like to 
generify it, or if it helps in the general thrust. I'm in the process of 
writing a blog post on our experiences for OKF archaeology subsection

Best

Ant
