Hi all, Sorry for the wide distribution. We wanted to make you aware (remind you in some cases) of the new working group called the Network Markup Language WG (NML-WG.) From the charter: "The purpose of the Network Mark-up Language Working Group is to combine efforts of multiple projects to describe network topologies, so that the outcome is a standardised network description ontology and schema, facilitating interoperability between different projects." The relationship of this group to the NM-WG is obvious as network measurement are a key user of representations of network topology. For the GHPN, those interested in dynamic Grid networks should be interested in the NML-WG as it represents a basis for topology exchange and pathfinding. Essentially, many groups have a need to represent network elements, and we believe that a single representation is ideal. That's a little misleading in that various levels of resolution make sense at different times, but some of us have the sense that a single representation framework can accomplish that. For more details, to participate, or to throw fruit and tell us the problem is solved/unsolvable/irrelevant or just plain out of our feeble depth, please join us in Seattle at OGF21. best regards, Martin and Paola
