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
