python client downloader

[white-gecko]

Currently the downloader returns TODO

$ databusclient download https://databus.coypu.org/narndt/coypu/example/
TODO

Are there any plans to support it? Currently also in the client.py there is no code for the downloader. Where would one find the relevant code in scala or what would one need to implement to support it?

Yes, it would be good to support it.
Start with

1. sending a SPARQL query to retrieve all download URLs**
2. store the files***: options: a) all into one folder, b) in a databus hierarchy like directory structure

IIRC. The Scala version is working with queries passed as CMD args.

There are several things to consider implementing it (that I have in mind)
** Support of different identifiers as file scope (user, groups, artifacts, versions, collections)
*** Configuration of the client (.dotfile, or cmd args) for local target directory, etc.

It is no longer TODO but still does not download a dataset:

$ databusclient download https://databus.dbpedia.org/ontologies/babelnet.org/rdf/2022.11.27-025337 --localdir . --databus https://databus.dbpedia.org/
dataId not supported yet

ok it seems to support either a custom SPARQL queries or download of a set of collections at the moment.
added another issue #6 to specify what is missing.
would close this issue can make new ones when they are more specific.
