Hi all,
Here are some of my considerations of database discovery mechanism on
differences between the independent LoST based mechanism and the mechanism
integrated in PAWS protocol.
(1) In the LoST protocol, an architecture for a global, scalable,
resilient, and administratively distributed system for mapping geographic
location information to URLs has been provided [refer to RFC5582],
and this architecture can be used for LoST based database discovery mechanism,
so it can be sure the discovery mechanism can be used globally. But for this
mechanism how the "Forest Guide" should be deployed
is an important issue to be satisfied.
(2) For the scheme that integrates discovery mechanism totally in PAWS
protocol document, there are also some considerations. Firstly, I think it is
better of this "Standards Track " document only focus on the PAWS protocol
and let the discovery mechanism not standardized, and this can give more
freedom on how to provide discovery procedure in different regulatory domain;
secondly, the mechanism described in paws protocol seems not scalable very
well, may be some more description needs to be provided.
