Discussion topics
No | Item | Presenter | Notes |
---|---|---|---|
1 | Opening | Rémy Giraud | Rémy, the architecture was already discussed in the last meeting, today discussion will focus on transition. |
2 | Metadata: |
o Enrico, limited number of catalogues lets easy to ensure the translation to the WIS2 catalogue, it’s useful to have it in automate way. o Rémy, need to engage with Regional Association, and involve National Centers (NCs) to rewrite metadata in accurate formats. o Baudouin. One of the reasons of the failure of WIS1 was the poor quality of metadata. Metadata was made in WIS1 to build the catalogue for human beings and not for computers. We should stop to have one metadata set for each message on GTS. o Tom, the translation will be done by NCs, and GISCs will be involved to help migration. o Peter, if we can get the work that we are doing in GTS to WIS to mapping to be bidirectional, the connectivity to GTS steals possible even if the GTS is dropped. He required that the new format of metadata to have legacy supporting the provision of the bulletin headers. This approach is easy transition to organize. o Hassan, most of metadata in the current catalogue concerns GTS metadata. The conception of metadata was the reason of failure of WIS1. A link to OSCAR will be valuable to WIS2 catalogue. o Enrico, need to analysis what we have in the catalogue and to think how to translate it in automatic way and to see how to have the link between WIS catalogue and GTS heathers as proposed by Peter. o Rémy, we have identified one or two ideas for potential transition, need for a volunteer to develop these ideas to be discussed in the next meeting. Enrico and Peter: will prepare a draft for the next meeting. Tom, Jeremy and Baudoin will prepare a paper about metadata. o Rémy asked the team to comment these papers before the next meeting. The objective is to have a conclusion on this topic of transition and metadata. o Enrico, informed the team that they can create new pages to develop a new proposal if needed. o Rémy, automatic translation from the current metadata to WIS2 catalogue is not the right strategy o Tom, translation will concern the structure but not the content. o Enrico, the need of involving NCs to modify WIS2 catalogue is an important part, we need to write a paper about it and discuss it in the next meeting. o Rémy, need to inform RAs through the engagement aspect about the changes as soon as possible. Start to communicate also to GISCs, DCPCs and NCs. | |
3 | GTS part: |
|
o To avoid the need for dual stack (GTS and WIS2) for as many sites as possible o To reduce the number of RTHs between now and the migration date. The idea consists to identify “super RTH” In each RA, willing to run GTS services until the end of the migration, so that others can cease GTS operation rapidly and act as WIS2 focal sites o Allow identified GISCs to stop the technical WIS1 role (cache and metadata catalogue) in favor of “WIS2 Champion” role (training, communication, shared service,…) o Promote the use of “WIS2 in a box”
|
4 | WIS2 champions: |
|
o Enrico, informed the team about the funding that can be provided by secretariat to develop the monitoring tool o Rémy, possibility to merge the monitoring and WDQMS teams and develop a global monitoring
o Enrico, need to take into account the restriction to data with limitation access o Rémy, the messages will include information about the access limitation o Peter, proposed to replace broker by webserver to deal with the limitation access or to have broker at NCs headquarter for national use. · Training/communication/onboarding: Identify members within each RA acting as WIS2 Champion (GISC and others)
o Similar to GDPFS portal, follow WIS2 implementation and provide a visual communisation tool to show WIS2 progress.
