a dublin core record inside of surrogate input files may now contain
tokens within the namespace 'md' (short for: metadata). The token names
must be valid withing the namespace of the solr field names. All
md-tokens inside of surrogate files then overwrite values within solr
documents before they are written to the solr index. This makes it
possible to assign collection names to each surrogate entry and also
ranking information can be added. Please see the example file.
