Re: [GeoNetwork-devel] Official way of representing OGC services in ISO 19139 metadata protocol ele

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

HI All,

As you have probably noticed I have questioned how the <protocol> values were determined for the GeoNetwork interfaces. Can someone tell me how the formats below came into use.

There is the official URN format for different authorities (eg. OGC, WWW, ESRI). Wouldn't it be more interoperable if these formats were used?

Thanks

John
