Implementation progress:

Michel - has almost got a complete implementation of OGSA DMI,
including support state lifetime but there are a couple of issues
remaining. Stay alive time will have units in seconds. WS-Addressing
actions and renaming the resume operation need to be fixed- other than
that fine.

Some of these will be fed back into the functional spec after the
interop process has concluded.

Steven - rebuilt the interface based on the current draft of the XML
distributed by Michel.  Steven has been communicating with Michel over
any issues that arise. His DMI implementation can do file transfers
based on ftp endpoints. Have to implement the transfer activity as a
separate thread so that it can be monitored and actioned by the
client.

Mario reported that Ravi has been busy but he will try to do
something.

Michel is away from 26 June - 4th July, back in the office on the 7th
of July.  Steven hopes to get something up and running by
then. Hopefully Ravi can come up with something on-line roundabout
that time.

Michel would like some of the stuff from the WSS namespace from Steven
to put his DMI credentials in. Steven is going to send him something.

Michel has been keeping an xls sheet with issues (because of issues
with GridForge).  More changes on the pipeline - three outstanding
ones:

Plain WS Rendering WS-Addressing Action values garbled. The
WS-Addressing Action values for the DTF and DTI operations do not
matching the DMI naming pattern.

Michel will fix and produce some new WSDL.

Specification 1.0 stayAliveTime ambiguous. The definition of the
stayAliveTime is ambiguous - there is no unit defined. Does the value
mean days? Minutes?

Use seconds for lifetime - integer values should give plenty of scope
for lifetime.

Plain WS Rendering 1.0 Resume operation rendered as "restart" The
Specification defines a "Resume" operation while the rendering uses
"restart" as verb for this operation

Operation to go back to being called resume.

Michel's noted that his implementation is WSRF compliant and that he
could use this for the WSRF rendering of OGSA-DMI.

Date of next call will be decided at some future point.
