When you give a definition of what is your understanding on the topic,
but the DNS definitions are not clear enough on this, i.e.:
- A domain includes all its subdomains?
- We need to worry about top-level-domains, country code top-level
domains, etc.?

In any case, to aggregate, is not the same as to compact.

That is your interpretation of domain. However, [1] is not that
categoric on whether a subdomain is not part of a domain. For others, it
might be so. By the way,
- example.org is a domain, and a subdomain of the TLD .org
- www-inter.example.org is also a domain, and a subdomain of example.org
- example.co.uk is a domain and a subdomain of the ccTLD co.uk

Thus your definition does not hold.

And who does guarantee that your crawler gets all resources? We have
tested several crawlers in big portals (10,000+ resources) and you get
different results with all them (not to mention they run out of memory).
That is why we developed our own anyways ;-)

Well, simply is EARL reporting *test results*, which lead to some
compliance with some given requirement (e.g., WCAG 2.0), or directly
compliance with the requirement? This issue is still open in my

I do see a problem, though ;-) namely, the misuse of EARL.
