This appears to be an oversight, however, the (DRS) institute is not harvested from ESG thredds catalogs. Most likely the curator.Institute should be used to support this property.

Based on initial review the following fix is proposed:

1) Add "Institute" String field to dataset
2) Add dataset handler for thredds property "institute"
3) Add triple store relationship for institute to dataset.
4) Harvest institute into TS
5) Expose institute as search category.
