Discussion of data transfer protocols
-------------------------------------

MM had looked at WebDAV, does it really apply?=20
Also at PBIO, looks like an alternative to XDR.
Bill Allcock recommended looking at XIO as well for background. Does ByteIO fit
more at the client API level?

MAA: What does PBIO stand for? - MM will pass on link

MTOM will be in WSE3.0 but unclear when it will be released. Axis2 has MTOM in
plans, but not yet done.

NCH try to ask Microsoft Europe contact whether WSE3.0 is coming out = soon and
whether DIME will still be around.

Discussion of use cases
-----------------------

Came up with a use case from the point of view of an NFS server = accessing a
ByteIO web service. Then a more grid aware application, = which knows about
ByteIO interface, so can make decisions. Have a client = which wishes a more
connection oriented view of a ByteIO stream, = establishes an endpoint, which
marks a particular position in a file.

One of the things which pops up is a way of locking the data source. Avaki
allowed the placing of an advisory lock, which is used by NFS = protocol, but
doesn't seem to be heavily utilised. People worry about it = but don't often do
anything about it.

Simple cases don't need locking but we will probably have a lot of = people
standing up at next GGF saying we need locking :-)

DAIS discussion of use case has revealed a possible hole in their =
specification to do with getting data into a data service (rather than = getting
data out). =20 DB contacted the NEC guys, and they sent along a simple
visualisation = application use case.

Use Cases - write some down, come up with a template on what we want to = get
from a use case, reformat our use cases into this format. what functionality
will be layered on top of ByteIO

[MM] Mail out a draft template for use cases for next Telcon.
