Hi, Terry,

Could you please review the code when you have a chance? Thank you!
I have deployed it to the aux box:
https://repository-aux.library.georgetown.edu/batch-tools//web/query/metadataRegistry.php

I have not added any style to the result page.

I have a question, do you think it is okay to merge all metadata field into one giant table? If not, I can separate them into separate tables.

Thank you!
Wei
