Changed the resource link of the viaf.org script in 5b93cc1 which is reachable. However the script will download a 9.1GB zip file. Should this be changed or this much traffic acceptable?

[m1ci]

I think 9GB is fine. Actually, we will always first need to approve a contribution, so I would not set some general requirement on the traffic, but decide on this at a contribution level.

What is the maximum size of a file? I would update the How To wiki page to insure that each contributor is aware of it and does not create scripts which generate an unnecessary amount of network traffic

[m1ci]

for a maximum size of a file, please look at the current files and set the size maximum size to a number where most of the current linksets fit in. 0.5GB, 1GB? dont know. As a note you can write smth like: "If your linkset generation needs to download more the 1GB of data, please contact the maintainers." What do you think?

[RPOD]

Sounds reasonable I will add that right away.

1. users can provide a download link
2. we can keep large stable files in http://downloads.dbpedia.org/links/resources/
3. maximum file size should be 50MB that is already a lot to handle for Git, each change will be logged indefinitely, so if a 50mb file gets updated 10 times it is 500 through all revisions, which you need to fully download on git clone.
