This process involves:
+
*[[METS]]
−
 
+
*[[PREMIS]]
−
# Using the InterPARES Chain of Preservation (COP) model and the CoP/PREMIS crosswalk to identify required elements for objects preserved by Archivematica
+
*[[PREMIS metadata: original files]]
−
# Analyzing existing metadata in the Archivematica AIP log files and METS.xml file in order to map them to METS and PREMIS elements
+
*[[PREMIS metadata: normalized files]]
−
# Comparing 1) to 2) in order to determine what gaps exist in Archivematica
+
*[[PREMIS metadata: events]]
−
# Filling in the gaps - eg by modifying workflow to produce and/or capture missing elements
+
*[[PREMIS metadata: rights - 0.10]]
−
# Structuring the required elements into the [http://wiki.fcla.edu:8000/TIPR/21 Repository eXchange Package (RXP) specification]
+
*[[PREMIS/METS for scalability]]
−
# Determining what metadata belongs in the DIP(s)

*[[RDF/OWL]]
