4. Query Interface Common Query Schema Methods
Came up with a Schema that is similar to SQL structure, but uses XPATH.
Methods
Search(QueryResources) – standard query method
KeyWordSearch(String word(s),boolean orAction) – Helper query method.

5. Harvest Interface
Only return VOResources that this registry manages (HarvestFrom, Harvest)
HarvestFrom(date dt) – harvest information from a particular date
Harvest() – replicate, get everything.
HarvestResource(VOResource) – harvest metadata from a particular Resource (Service)
GetRegistries() – find about other registries.
