Re: [GeoNetwork-devel] [GeoNetwork-users] metadata validation / gmd:MD_Metadata namespace

[Timo P. <ti...@pr...>]

Hi,

I have found the reason for the error and it might be a bug.

Technically it is because my MD record uses the gmd namespace. The
iso19139 schema specifies the gmi as "target schema" and this is my the
method findSchema fails.

However, findSchema should IMHO not be called at all, since it is only
used to find a prefix for MD not having one. (mine has one).

DataManager:2861 (setNamespacePrefixUsingSchemas ).

//--- if the metadata has no namespace or already has a namespace prefix
//--- then we must skip this phase

Namespace ns = md.getNamespace();
if (ns == Namespace.NO_NAMESPACE  )
   return;


I have changed this  to:

Namespace ns = md.getNamespace();
if (ns == Namespace.NO_NAMESPACE || !ns.getPrefix().equals("")  )
     return;

I do not know the repercussions of this, but maybe I found a bug.

best
Timo
