[gdal-dev] Call for discussion for "RFC 43 GDALMajorObject::GetMetadataDomainList()"

[Even Rouault]

Hi,

This is a call for discussion for "RFC 43 
GDALMajorObject::GetMetadataDomainList()" :

http://trac.osgeo.org/gdal/wiki/rfc43_getmetadatadomainlist

Beginning of the RFC inline :
"""

== Summary ==

This (mini)RFC proposes a new virtual method, GetMetadataDomainList(), in the 
GDALMajorObject class (and a C API) to return the list of all available 
metadata domains.

== Background ==

GDALMajorObject currently offers the GetMetadata() and GetMetadataItem() 
methods that both accept a metadata domain argument. But there is no way to 
auto-discover which metadata domains are valid for a given GDALMajorObject 
(i.e. a dataset or raster band). This make it impossible to have generic code 
that can exhaustively discover all metadata in a dataset/raster band.

[...]

"""

Best regards,

Even
