Yes, that covers my first question. I have also seen Anssi’s CSP extension

way to securely open up sensitive APIs to server hosted web sites using a signed 
manifest and secure transport.


This indeed a major concern.  Permissions and "Trustworthy Code" are 
unfortunately not particularly related.

Cheers,

Then we have to work on any needed extensions to the Manifest specification.

Yes, indeed. I just didn´t remember the final name.

Does that cover your first question?

Regarding the second questions, Anssi wrote an extension spec: 
http://w3c.github.io/manifest-csp/

He can probably comment on that.

Ok thanks Kenneth. I assume that you refer to the Trust & Permissions Community 
Group, https://www.w3.org/community/trustperms/?

Hi Claes,

The web app manifest spec allows extensions (it has extension points), so we 
would expect the Permissions WG/CG to come up with a proper way to deal with 
permissions. If they come to the conclusion that we need some permission field 
in the manifest, their spec can add that. It is not yet clear at this point 
that that is the solution that they are aiming at.

Cheers,

Kenneth

Hi,

We support that this version of the specification is moved to Candidate status 
but we have a few comments/questions:

In this version 1 we miss:

* A "permissions" field
* A "content security policy field". This is only included as a way to state 
allowed origins from which the manifest file itself could be loaded. However, there is, 
in this first version, no CSP-field defined for the manifest document, allowing 
restriction of origins the web app could download scripts and other content types from. 
There is also a draft companion document, http://w3c.github.io/manifest-csp/, defining 
this CSP-member of the manifest.

We consider the above features important for allowing server hosted web apps 
access to more sensitive APIs and have been experimenting with this for FFOS:
https://lists.w3.org/Archives/Public/public-sysapps/2014Sep/att-0000/SoMC_FFOS_Trusted_Hosted_Apps.pdf.
 Accordingly we want to discuss these features for the further work on the 
manifest specification.

We also would like to ask the WG if it has been discussed if https: transport 
should be required for downloading the manifest? Other specifications are 
moving towards requirement for https:. See for example the discussion 
https://lists.w3.org/Archives/Public/public-device-apis/2015Feb/0045.html. For 
the manifest version 1 this may not be critical but if above features are added 
the transport probably have to be protected.

However, once again note that these comments do not prevent that we support 
that the current version of the manifest is moved to candidate status, I am 
just taking the opportunity state our views on the further work on the manifest 
specification.

Best regards
