This will allow to use simple LDPath statements for property mappings during the indexing of datasets.
While the default mapping language supports a lot of use cases for mapping, converting and filtering of properties it is by far not as capable as [LDpath](http://code.google.com/p/ldpath/). Because of that the indexing tools has also support for using LDPath to process entities by using the "LdpathProcessor".
A typical usage example of the LdpathProcessor processor are type specific mappings such as
skos:prefLabel = .[rdf:type is diseasome:genes]/rdfs:label;
This specifies that only for entities of the type "diseasome:genes" the rdfs:label is mapped to skos:prefLabel. rdfs:labels of Entities with other types will not be mapped to skos:prefLabel by this rule.
