Comment:

GridFTP is a protocol that does not offer a close enough fit to reason references or integration with ByteIO in the min specification, as it does not 
offer partial resource transfer (on hte level of file system files).

While ByteIO could be used to do download an entire resource, this is nt the anticipated and modeledd primary use case for ByteIO.

Therefore the group decided to not include a URI for GridFTP in the main ByteIO specification.

Comment:

While I am not objecting adding other protocols as currently defined (or profiled) for ByteIO, I raise the issue of GridFTP not being a suitable 
protocol supporting ByteIO.

The reason is that GridFTP, as it is based on plain old FTP, does  does not support partial transfers of resources.

So, in an attempt to add GridFTP as a protocol for ByteIO, using GridFTP might apply just for the cases that the user want to transter the whole 
resource using ByteIO (as an agreement protocol) - which, unfortunately collides with the ByteIO requirement of short reads and short writes. GridFTP 
siimply is incompatible to that.

The case is different for Parallel HTTP (or HTTP in general). For this, I will add separate trackers.

Comment:

We agreed to add a unique name and protocol for GridFTP as a MAY to the list, as it is stable and defined in GGF.

We need to identify someone who will commit to doing a  byteio implmentation which uses GridFTP.
