 1. unlv_image: A local implementation of the Islandora Image module to include additional metadata fields.
 2. migrate_cdm: Uses the Migrate API to load Tiff masters, metadata exported from CONTENTdm, and authority records exported from [TemaTres v.2](http://www.vocabularyserver.com/)
 
+*Note:* This proof-of-concept assumes that new content types will be created for each metadata profile/object type pair; ergo, this proof-of-concept includes a new content type called UNLV_image which parallel's islandora_image but adds some node entity references. However, the CLAW team is exploring alternative strategies for managing descriptive metadata which will make portions of this example out of date (hopefully soon).

 # Source Data
 
 The source data used for this proof of concept came from the UNLV Special Collections and Archives but are not in the public domain. As such, the metadata files are provided (in the data directory) but not the original Tiffs. This version is being committed for the sake of expediency although I will follow-up with another commit using public domain images ASAP.
