Topology Representation Doc
by Jeroen van der Ham 06 Feb '13

06 Feb '13

Hi all, Attached is the latest version of the Topology Representation doc. It still lacks a definition of an STP (which would be very welcome), and I still have to update the bibliography. Jeroen.

Topology Exchange format
by Jeroen van der Ham 05 Feb '13

05 Feb '13

Hi all, Yesterday we've had a short discussion on the call regarding the topology interchange syntax for NSI. We need to make a decision on this soon, because the implementers need it. Before we get to the options let me make a few things clear: - This is not about the terminology for the topology representation. As a group we've basically reached consensus on the extensions on NML that are required for NSI. I am currently writing these down and will soon send that doc to the list. - This is not about the Topology Service itself. The exact working of the Topology Service still needs to be defined. The requirements of that are currently being written down in another document, after which we can have a coherent discussion about the implementation. - All options listed are valid NML + NSI extensions, and all represent the same abstract models. NML allows for different syntax representations of its model. We have been using different formats for the AutoGOLE demonstration, but this is hurting the implementors since it is not clear which one they should support. With that out of the way, the three possibilities are below: - Plain XML, a direct codification of the NML & NSI concepts into XML. This has not been used so far. - OWL RDF/XML, an RDF representation in XML. This has been used with the DTOX format in the NSIv1 demo, and the NSI format has also been available for the NSIv2 demo, although only used by OpenDRAC I believe. - Notation3, a terser RDF representation. This has been made available since the NSIv2 demo, and used by many different implementations. We should decide on at least one format that must be supported by all implementations. We can also make the other syntaxes optional, if we have a good mechanism to describe the supported options. Jeroen.

NSI sessions at OGF37
by Guy Roberts 01 Feb '13

01 Feb '13

Hello All, I have been told that we can get extra sessions at OGF37 - I have now requested 6 and I can increase this if necessary. So far I have asked for the sessions to be on Monday and Tuesday - I note that there is workshop on federated ID/AA on Monday, is anyone interested in attending this? If we want to keep Monday free for the workshop then we may need to shift a few sessions to Sunday or Wednesday. If you are planning to attend, could you please let me know if you would prefer Wednesday or Sunday sessions? Thanks, Guy _____________________________________________________________________ Guy Roberts PhD Senior Transport Network Architect DANTE Cambridge, UK +44 1223 371316 DANTE is the project co-ordinator and operator of GÉANT, the high-speed pan-European research and education network that is transforming the way researchers collaborate.
