[ckan-dev] [ckan] Would be good to find another solution for the dataset URL rather than one generated from the dataset title (#1233)

Hi,

I've faced this difficulty in my application, due to business requirements.

In my case, I would like to allow users to upload files which would 
possibly have the same title. For example: "rain" data is probably 
different from different locations, but users on those different 
locations still call what they observe "rain". You know... if you have 
user B trying to upload _/resource/_ "rain.csv" but user A already done 
that, CKAN will not permit duplicate names. Employing distinct UUIDs 
does not help because, despite URLs will be certainly different, 
_/resource names/_ in CKAN database would still be the same, which is 
not allowed. Similar trouble happen with package (dataset) names, for 
example.

In order to solve the problem, I've created a layer on top of Action API 
and "FileStore API" (sic) which manages (from the business point of 
view) how I create users, organizations, packages (datasets) and 
resources. This layer also makes life easier to upload files. In a 
nutshell, this layer is responsible for making sure that object names in 
CKAN database are distinct, even if _/apparently/_ they look the same 
(have same names/titles) when user A and user B see these objects.

At the moment, I do not allow users to visit the CKAN instance directly, 
I mean: users manage objects using my web application, not CKAN 
directly. So, the layer I've mentioned can be called locally (in the 
same server) without spending any additional time with calls over the 
network. CKAN does not even respond to HTTP requests in my installation, 
because I access CKAN functionalities locally via CKAN API.

Cheers :)
