Profile is a url rather than string

[rufuspollock]

Switch from:

  "profile": "tabular-data-package"

  "profile": "https://specs.frictionlessdata.io/schemas/tabular-data-package.json"

Why?

Reduce magic! See frictionlessdata/frictionlessdata.io#875

• Tools no longer have to go through some discovery mechanism to resolve schema path
• We don't need to maintain some registry
• Versioning can be explicit! Change the url. No need to invent special version - see Adding a version to profile attribute (or doing this via a "spec" namespace) #444

@roll @akariv @pwalsh does this sound good to you?

[akariv]

Yes, I agree it's better this way.

[roll]

Sure regarding validation but I have another question - will it still be an indicator of a resource type? (tabular or not). If yes, how to handle it (checking equality to exact URL e.g.)?

[pwalsh]

yes, better.
