Hi Dave,

WMO issues news release that WIS Discovery metadata is available at GEOSS.  Congratulations, first of all.  That should be a great step.

Which gisc works as gateway?  I'm more than simply curious.  It should be good to know that for stable operations I think.

Best,
Eizi

Hi Eizi,
Good point and fair question. 

GEOSS is harvesting from Offenbach. Timo is working with GEO to establish a backup GISC. 

You will note that the news release highlights that this is available both ways (eg find GEOSS from WIS too) as required by congress quoted in the article. Interestingly, I have had trouble finding the GEOSS connection from the GISCs. So far I can see the following do from the SRU search


but the following don't (or at least not obvious to me)

I am sure this requirement is probably met by all GISCs but it is not easy to find in any. I am not even sure how Toulouse and Exeter support SRU. I suspect it is hidden under the user interface, but I have not fully explored both sites at this time. It would be good if each GISC explained how to search GEOSS (and other remote SRU servers) from their site so we can put it on the main GISC page www.wmo.int/giscs. Normaly I use the SRU training page when showing this facility, then use DWD as the example GISC.
regards
Dave

Thanks Jacques
I'll give it a go and also update our sru training page to include your sru server.

Your url is the good one but you need to add <portal.sru> to plug to the sru server
For Toulouse: http://wispi.meteo.fr/openwis-user-portal/srv/en/main.home/portal.sru
An example of sru question on the GISC Toulouse OpenWIS SRU server (question about La Reunion Island): http://wispi.meteo.fr/openwis-user-portal/srv/en/main.home/portal.sru?operation=searchRetrieve&version=1.1&query=%22reunion%22&startRecord=1&maximumRecords=10&&

Hi Jacques
I have added your SRU server to the SRU training page today. It should be available soon. See  http://www.wmo.int/pages/prog/www/WIS/wissruform.html 

And look for Toulouse
thanks

Jeremy,

I recall a discussion at our Exeter IPET-MDI meeting that we were not pursuing SRU.

Is this no longer the case? Perhaps I misunderstood the conversation.

Hi Bruce,
 
I'm afraid I don't recall the conversation, but I'll try analysing the situation.
 
As a matter of regulation, the Manual on WIS states
"4.9.1 This specification requires that each
metadata catalogue host shall support the Search and Retrieve via URL (SRU) specification of the
ISO 23950 Information Search and Retrieval Protocol."
The word "shall" means mandatory.  The manual also mandates some indices of SRU.  You might know SRU has no technical relation with ISO 23950 at all (please check specs if you doubt), but the manual text is a compromise between those who needed clear meaning and those who wanted some feeling of authority or neutrality (I don't know).  Anyway SRU is a nice open standard, and I love to have open interface for sense of transparency.
 
Regarding value, however, there is no answer yet to the question "why it is necessary, or even useful, for each WIS catalogue to have SRU interface?"  Standardization of the search interface is meaningful if we need a parallel (distributed) search to different catalogues, which are not present in current WIS since people really pursued global syndication of metadata catalogues.  In simpler words, "Why we don't just let people search at a GISC (instead of DCPCs) as it has entire set of WIS metadata?"  Or now we can say "Why we don't let people search at the GEO Portal as the WIS metadata is a part of GEOSS metadata?"  In short, the manual is still in the evolving process.
 
Please note I'm not trying to abolish anything (Dave, don't get mad please).  The two approaches (distributed search by SRU and syndication by OAI-PMH) are both invested in the library science community.  It might also be useful if a couple of GISCs provides mutually backed-up service of SRU to other parties if machine-readable search gets more popular.  Nothing wrong in research.
 
But for many people right now, more pressing agenda exist somewhere else, for example launch of WIS centres or successful migration from existing catalogues like Volume C1....  I think "not pursuing" is something like that.
 
Hope my thoughts are useful.
 
Eizi

Sru is the standard as per the manual on wis. This can only be changed by CBS recommendation to Cg or EC, or from EC or Cg themselves.
