perma.cc helps scholars, journals, courts, and others create permanent records of the web sources they cite. For information, see https://perma.cc.

Memento Protocol Information

perma.cc is accessible via the Memento "Time Travel for the Web" protocol. Hence, it supports datetime negotiation to access a version of a web resource as it existed at a specific moment in time. Check out the brief introduction to Memento if you are not familiar with it.

Presuming the Original Resource (current version) is http://www.cnn.com/, then the resources that are relevant for the Memento protocol are:

TimeGate: https://perma.cc/timegate/http://www.cnn.com
Memento: https://perma.cc/LE2T-J2HJ ; etc.
TimeMap: https://perma.cc/timemap/link/http://www.cnn.com

Integration with the Original Dataset

The original dataset is the web at large. In responses to HTTP requests, Web resources typically don't provide a Link header with a "timegate" link to point at their TimeGate at the perma.cc.
