Sure, I'm just wondering about the possible use cases we have when the file is not publicly available. My guess:

A - local files (file://...)

It usually happens when teams work on templates or when there are really small teams that produce "handmade" websites (usually static), not sure if EARL has something to do with this case.

B - local testing servers (localhost://...)

Mainly again in small projects, but I think that they have different characteristics (usually dynamic web sites). Probably this use case is more relevant for EARL that the previous one.

C - internal testing servers (

Used under development before production stage. This could match with the trusted external evaluation team you commented. EARL should be able to cover this uses case.

So my impression is that there are enough differences to justify the creation of a new specialized class and we need something more generic that FileContent to allow us the acommodation of all previous use cases.

Well, there could be some "security" or "privacy" concerns that prevent people to expose the whole path as pointed by Charles before [1]. Anyway neither of them are useful as unique identifiers so we could use whatever of both just as labels.

And that's why I think we need some property (other than the file content, which is too hard to manage as identifier) that works as a identifier. My justification for this is basically that if you want to share the results (for example with an external evaluation team) you need an unique identifier (for example, is supposed that the external team is going to manage more projects).

Finally, another issue that have just came to my mind is:

How should we manage that content which is avalaible on the web, and thus we can use the WebContent class, but has restricted access (e.g. proxy or user and password), and thus fits more in the "NonPublicContent" concept? 

Should we redefine the WebContent class as "Information that is PUBLICLY AVALAIBLE on the World Wide Web" and then create a "NonPublicContent" that includes file content, password protected content, etc.?
