Objects not show up

I followed the tutorial, but the objects are not showing.

@tsing-xu in your project's _config.yml you have the value
metadata: datacollection
which does not match any CSV name in your "_data" folder.
You have one CSV named "data_collection.csv", to use that you would have to edit your _config.yml to look like:
metadata: data_collection

Note that in the "data_collection.csv" it looks like you have PDF items in the "filename" column. You will want to update the "format" column values to match the file type. Currently it has image/jpeg which you will have to update to application/pdf for PDF items.
