I am working on Ckan development environment version 2.7.2. I wanted to know whether it is necessary in CKAN extensions which are made by themselves will be licensed under AGPL only. ?

Yep, that is my understanding :)

Such is the benefit of a high-reciprocity OSS licence. Which, is why the license is uniquely appropriate for an open source project which has a focus on publishing Open Data.

However, please seek your own legal advice with regard to your particular circumstances.

Cheers,
Steven

Thanks for your reply.

My furthur queries are 
1. Are there any several terms or not while creating extention of CKAN ?
2. What are the rules of license for CKAN extentions
3. Is it necessary that CKAN extentions made by community or anyone will be licenced under AGPL ?

Now, What my understanding is when we create CKAN extention or plugin, we must use SingletonPlugin which is a part of core CKAN code, which is again under AGPL licence.
So According to copyleft, we need to use AGPL licence for extention. 

Let me know if my understanding is right ?

Sorry for my practiced ignorance on the details. Everything my company does is open by default so all I can say is please seek advice from your own council on such matters.

I have no experience on what ‘can’ be closed source and no incentive to investigate such boundaries.

In my view, once you go open source you are ‘all in’ for the greater good of all :)

Cheers,
Steven

Just reread my reply and apologize as it sounds rude!

I should have said, if you do seek council and and advice on such matters then please do share with this group :)

Although I may not have pursued such a path it by no means would suggest that such an effort is not worthy of further investigation.

Cheers,
Steven

Agreed. CKAN plugins are "linked" to CKAN when you run them, creating a "combined work". The argument that the FSF makes (and is generally respected) is that the "combined work" (i.e. CKAN and its all the plugins running) must be licensed under AGPL. It follows that all CKAN plugins that you run publicly should have their source published and with the AGPL licence. (I am not a lawyer.)
