[Fiware-ngsi] Missing target namespace in XSDs

Thanks for clarifications, it is clear.

Then I would suggest to use fi-ware_ngsi9 and so on, just to avoid possible further confusions with others OMA NGSI derivations. What do you think? Shall we change it to these below:

https://forge.fi-ware.eu/schemas/fi-ware_ngsi9

https://forge.fi-ware.eu/schemas/fi-ware_ngsi10

https://forge.fi-ware.eu/schemas/fi-ware_ngsi_data

The second my question is still pending ;-) (to entire NGSI FI-WARE list though).

Best Regards,
Boris

Dear Tobias,

You are right.

This fragment for wikipedia (http://en.wikipedia.org/wiki/XML_namespace) is not an "official" source, but it is quite clarifying:

The use of URIs taking the form of URLs in the http scheme (such as http://www.w3.org/1999/xhtml) is common, despite the absence of any formal relationship with the HTTP protocol. The Namespaces specification does not say what should happen if such a URL is dereferenced (that is, if software attempts to retrieve a document from this location). One convention adopted by some users is to place a RDDL<http://en.wikipedia.org/wiki/RDDL> document at the location.[4]<http://en.wikipedia.org/wiki/XML_namespace#cite_note-4> In general, however, users should assume that the namespace URI is simply a name, not the address of a document on the Web.

Best regards,

Hi Boris,



As far as I know (but maybe I am wrong) URIs used for namespaces do not have to be accessible, they are more used to make sure global uniqueness of the namespace.

Tobias

Hi Guys,



it seems that the links from Fermin's email doesn't work. I'm logged in and see "PAGE NOT FOUND"... may you have a look at the issue, or is it may fault? Thanks.



What about the inclusion of Sergio into the NGSI mailing list? Do we have a formal admin for that list or shall I ask for this to Juanjo?



Thanks again and best regards,

Boris

Hi Fermin, all,



Yes, I think a target namespace would be good. Actually I was not even aware it is missing - at some point we had one.

I am also happy with your namespace suggestions.

Tobias

Hi,



I guess by the lack of answers that we haven't defined namespaces so far :)



In that case, I would suggest following ones:



For Ngsi9_Operations_v07.xsd

https://forge.fi-ware.eu/schemas/ngsi9



For Ngsi10_Operations_v07.xsd

https://forge.fi-ware.eu/schemas/ngsi10



For Ngsi9_10_dataStructure_v07.xsd

https://forge.fi-ware.eu/schemas/ngsi_data



What do you think?



Best regards,

Hi,



Working on the IoT chapter integration scenario I've realized that we

are not specifying any target namespace (targetNamespace=...) in the

XSD at:



https://forge.fi-ware.eu/scmrepos/svn/iot/trunk/schemes/Ngsi9_Operatio

ns_v07.xsd



https://forge.fi-ware.eu/scmrepos/svn/iot/trunk/schemes/Ngsi10_Operati

ons_v07.xsd



https://forge.fi-ware.eu/scmrepos/svn/iot/trunk/schemes/Ngsi9_10_dataS

tructure_v07.xsd





So, what it the namespace for each one of these schemas, please?



Thanks!



Best regards,
