This page identifies a minimum set of metadata elements designed to ensure authenticity and interoperability of preserved objects and to facilitate their retrieval.

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 (see [[Existing 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]]

==Proposed PREMIS metadata for original file==
 
−
 
 
−
This table is a template for metadata elements for the original file. Please note the following:
 
−
*The significantProperties semantic unit would be repeated as needed to capture all the significant property data produced by FITS.
 
−
*For most files, the relationships semantic unit would be used twice: once for the preservation copy and once for the access copy
 
−
*The event elements included in this table are an example only; a real PREMIS file would contain information about numerous events
 
−
*There will be at least two agent entities: an organization, such as City of Vancouver Archives, and Archivematica. The organization would be the agent for manual events such as reviewing the SIP, while Archivematica would be the agent for automated events such as normalization.

Unlike the table above, this table shows all the metadata elements that should appear for a normalized file. The two events recorded are creation and checksum generation.
