This strategy is the same as the previous one (http://rhq-project.org/display/RHQ/At+least+one+parent) except that it always shows the ancestry up to the top-most server or service directly under the platform. The platform is only shown in the ancestry if it is needed to disambiguate the resource.
The top and bottom resources are disambiguated using the path to the top-most server. The middle two are disambiguated using the plugin name but the ancestry up to the top-most server is shown anyway.
Again the only change to the previous strategy (http://rhq-project.org/display/RHQ/At+least+one+parent) is the ancestry shown up to the top-most server.
The same just for the reference.
And again. The platform has no parent, hence no ancestry to show.
