What's the pattern for numerous files as raw data? I want to download about 2000 files of the same type with different dates, e.g. "senate_2006-03-30.xml". 1. Do I create a catalog entry for each file? 2. Does the download-node

output

to a list of length 2000, i.e.

["senate_2006-03-30", "senate_2006-03-31", ...]

, i.e. a 2000-line

pipeline.py

? Or is there some sort of clever templating?
