The GGF ByteIO WG provides a set of specifications to provide an interface for reading and writing sequences of bytes in a POSIX like way. It aims to be a lowest common denominator specification for transferring bytes. Within the specification it also proposes a scheme for describing data transfer mechanisms. These specifications have now completed their initial GFSG Review, and have just entered their public comment period. We would encourage people to submit: 1. Technical comments on any aspects of the specifications, in terms of their scope, clarity and correctness. 2. Comments from application developers on the suitability of the specifications for their use cases. 3. Comments from organisations that may be interested in implementing the specifications, for evaluation, for use for a specific purpose, or as part of a wider platform. 4. Comments from other groups who are interested in using ByteIO (or parts of ByteIO, e.g. the data transfer identification scheme) as a basis for other specifications. Comments can be made via the following links (where you can also get copies of the relevant documents) ByteIO specification http://forge.gridforum.org/tracker/index.php?aid=1692 ByteIO OGSA WSRF Basic Profile Rendering 1.0 Specification http://forge.gridforum.org/tracker/index.php?aid=1693 Although detailed comments are preferred, even top level comments expressing approval or disapproval with the specification are useful. We currently have three implementations in progress, however any offers for further implementations or implementation use cases are again, gratefully received.
