Class ExistingMetadataLoader  

java.lang.Object
  org.greenstone.gatherer.msm.ExistingMetadataLoader

---

public class ExistingMetadataLoader

extends java.lang.Object

Attempts to locate and import any metadata already attatched to files about to be imported. This entire function is part of a critical file copy and so must be fast and reliable (or at least recover nicely when things go wrong). Futhermore this process must be aware of concerns such as previous greenstone collections having metadata sets that could be immediately imported, or hierarchy files needed to turn indexes into something more meaningful. We also must allow for the extensibility of this class to include custom metadata objects such as MARK records etc.

Version:
