[Biopython-dev] support for database of BOLDSYSTEMS?

[Peter Cock]

Hi Carlos,

I've not done anything with Twisted or other asynchronous mechanism
for accessing online resources - services like the NCBI discourage
submitting multiple requests in parallel anyway.

One idea might be to leave that to the library's user, and focus on the
lower level API (building the URLs, parsing the returned values, etc)?
