I'm writing an application that will take i/p URL of bitstream , chck
its exsistence in DL and get metadata for that. How can i check its
existence in DL? My idea was- i wrote a query that checks the column
items table. Is that a correct way? And is there a way we can create a
seperate submission process for my application to call to fill in
metadata and upload my application file in addition to the present.
