NEW RELATIONS: timegate ; timemap ; memento ; original

[Herbert van de Sompel <[e-mail]>]

Hi all,

I would like to request adding the following Relation Types to the Registry:
- "timegate"
- "timemap"
- "memento"
- "original"

These Relation Types are used in Memento "Time Travel for the Web" for
which a new Internet Draft was just published at
http://www.ietf.org/id/draft-vandesompel-memento-06.txt

I include the description of each Relation Type below. For
completeness, I also include the meaning of the terms TimeGate,
TimeMap, Memento, Original Resource as introduced in the Memento
specification:

   o  Original Resource: An Original Resource is a resource that
exists or used to exist, and for which access to one of its prior
states may be required.

   o  Memento: A Memento for an Original Resource is a resource that
encapsulates a prior state of the Original Resource.

   o  TimeGate: A TimeGate for an Original Resource is a resource that
is capable of datetime negotiation to support access to prior states
of the Original Resource.

   o  TimeMap: A TimeMap for an Original Resource is a resource from
which a list of URIs of Mementos of the Original Resource is
available.

Greetings
