Hi Carl,
Thanks for the reply.
I was expecting a web site/registry that will show me the full the list of available URN for the different authorities. Especially the OGC URNs for services etc. It would also be really nice to have them in an ISO 19139 code list catalogue XML format, but that may be expecting too much.
I have noticed that the GeoNetwork uses the following syntax for the types of protocols in its ISO 19139 metadata:
WWW:LINK-1.0-http--link
WWW:LINK-1.0-http--samples
WWW:LINK-1.0-http--related
WWW:LINK-1.0-http--partners
WWW:LINK-1.0-http--rss
WWW:LINK-1.0-http--ical
WWW:DOWNLOAD-1.0-http--download
WWW:DOWNLOAD-1.0-ftp--download
OGC:WMS-1.1.1-http-get-map
OGC:WMS-1.1.1-http-get-capabilities
OGC:WFS-1.0.0-http-get-capabilities
OGC:WCS-1.1.0-http-get-capabilities
OGC:WMC-1.1.0-http-get-capabilities
GLG:KML-2.0-http-get-map
ESRI:AIMS--http--configuration
ESRI:AIMS--http-get-image
ESRI:AIMS--http-get-feature
I don't know where this syntax came from but it would seem to me that using the official URNs would be better for interoperability between CSW. For example, (if I understand the specification correctly)
OGC:WMS-1.1.1-http-get-map
would be
urn:ogc:serviceType:WMS:1.1.1:getMap
(Though I'm guessing the content after the "WMS" string.)
The URLS in the OGC-NA_Name_type_specification_-_definitions.pdf (http://www.opengis.net/register/ogc-na/authority, http://www.opengis.net/register/ogc-na/namea and http://www.opengis.net/register/ogc-na/def-type) aren't available.
Is there somewhere where I can get a list of all the different URNs for each authority?
Thanks.
John

I believe that the Board being referred to is the OGC Naming
Authority.
Simon Cox is the Chair. There are 7 OGC Members who comprise
the board. The
formal approved policies and procedures documents for this are here:
http://www.opengeospatial.org/ogc/policies/directivesA draft OGC-NA page is here: http://www.opengeospatial.org/ogcna
The urn resolver is in alpha. We hope to formally bring it
online later this
year. There are many additions that need to be done.Anyway, the resolver will use an official OGC urn registry.
Regards
Carl
