Appraisal Arrangement tab

Main Page > Development > Requirements > Appraisal and Arrangement Tab

Background

The Bentley Historical Library has a Mellon grant which is sponsoring development on the foundational project to create an Appraisal and Arrangement tab. This tab will function as a place between Transfer and Ingest where archivists can make archival appraisal decisions with material from Transfer, and structure an arrangement for the SIP before starting Ingest processes. As of the Archivematica 1.3.0 release, the arrangement/appraisal decisions are made at the top of the Ingest tab by selecting transfers from the backlog for arrangement. This process, including the transfer backlog search, is to be moved into the new Appraisal and Arrangement tab.

Older requirements for similar functionality:

Requirements

Data

Data gathered during the Transfer stage has the potential to be used in the Appraisal/Arrangement tab for reports and visualizations. Below is a (currently unordered) list of potentially required data:

What data points about the objects themselves? Filename, format, MIME type, other?
Bulk Extractor reports (which ones? how to view?)
Directory printer text file -or- METS.xml structMap (same info)
File format information (grouped by file extension? by PRONOM ID?)
Size of content (space on disk), number of files
Viewer based on format ID
logs (virus scan, format identification, etc)
Other?

ArchivesSpace resources

How will ArchivesSpace resources be displayed for matching? Questions for requirements gathering:

How many resources and at what level should be loaded in the tab?
What options does the user have to search for existing resources?
How does the user create a new resource?
What data points are displayed (labels, level of description, other)?

Querying/filtering

What are the requirements for querying or filtering the data gathered above?

Workflow questions

These are some questions related to workflow that have arisen since the early development of the Tab:

Given the ability to produce a refined list of digital objects in the File List pane:

1. Is it necessary to be able to filter by format or PUID from the backlog, or only from the refined list?

Sample workflow:

User performs search of backlog and populates backlog pane
User selects transfers relevant to their purpose
User then filters the selected transfers by a specific file type, which populates the File List pane?

Answer: Selections from the backlog pane inform what shows up on the analysis pane and selections from the analysis pane in turn inform what shows up in the file list. Actually, that's why we'd like to be able to click on more than one piece of the pie at a time, or on more than one file type from the report at a time, or on a FPR group.

2. From where does a user drag files in order to create a SIP? From backlog, the File List pane, or both?

Answer: In our discussions, the user would drag and drop from the backlog. This is because, at least for us, arrangement will most likely be based on the original directory structure or the tags we've applied, but probably not often on something like file format or type (important for appraisal to be sure, but not so much, at least for us, for arrangement). As such, dragging and dropping right from the file list isn't something we really considered.

Mockups

Version 1 of the transfer backlog/reporting pane:

Screenshots during interim development period, July 2015:

New functionality identified during this period includes tagging content while processing the backlog, as an "aide memoire"- in this example, a reminder that some material will be discarded from the accession.

Technical architecture

An initial mockup of the appraisal tab has been started, developed as an Angular.js app. The code is available on github.

The basic idea is to create an Angular app, that communicates with the Archivematica Dashboard via its REST api.
