Metrics requirements

Documentation > Requirements > Metrics requirements

Description

• The Archivematica team is currently gathering metrics requirements to support digital repository management. The question we would like to answer is: what kinds of metrics would be useful to Archivematica users (e.g. performance/usage statistics, AIP/DIP monitoring, file format statistics, etc.).

• Our goal is to get a sense of the foundational elements necessary to fulfill future reporting requirements that we will need to build into Archivematica ... eventually. We are of course limited by available funding and time. We will prioritize the metrics and do our best to get as much as we can into upcoming releases given available funding and time.

3. number of failed normalizations per format x
4. name of person who processed an AIP

Data Model

-Logged-in user (should be captured as PREMIS agent) -UUID of the Archivematica instance (should be captured as PREMIS agent) -Possibly also environment data: what machines did Archivematica live on, what versions of all the tools were installed (already in PREMIS events), what version of Archivematica was used (already in software agent).

For AIPs:

-AIP name - In METS structMap:

-AIP UUID - In METS structMap:

-AIP storage location - Not in METS file -Date placed in storage - Not in METS file -Date updated (when we have AIP versioning) - will be in METS header <metsHdr CREATEDATE="2013-05-09T15:00:00" LASTMODDATE=”2014-02-09T21:00:00> -AIP size - Not in METS file -Related DIP - Not in METS file -DIP storage location - Not in METS file -DIP size - Not in METS file -Date DIP uploaded - Not in METS file

For transfer backups:

-Transfer name

-Transfer UUID

-Transfer size - Not in METS file -Transfer storage location - Not in METS file -Date placed in storage - Not in METS file
