Improvements/Reporting

Synopsis

This project is being sponsored by UCLA Library and NYPL Special Collections but more collaborators are welcome! Please get in touch on the community user forum.

Archivematica is designed to be very AIP-centric but users want to be able to access common files (commonalities could include file type, date ingested, tools used to generate metadata, or other) across AIPs. For example, a user might want to know how many PDFs were ingested across all AIPs between January and June of 2017. Alternatively, a user might want to run a file identification report before creating a SIP that identifies file types as a form of high-level analysis or scan of what is contained in the transfer.

This improvement was proposed in 2015 and some work was done (see Status 2015 and Analysis 2015).

List of example searches and expected responses.

The goal of this project is to be able to query the Archivematica database to locate the total number of files in the storage service by its PRONOM fmt/id.

User story

As a repository manager I want to be able to search across AIPs to locate how many of a certain file type I have. Ideally, I'd like to be able to narrow my search using date or other parameters.

Development tasks 2017

• Rebase search dev PR - done
• Evaluate if this allows us to remove tastypie in favour of Django REST framework (yes/no/maybe?/both) - done, answer is both
• Evaluate if search branch is able to answer the clients’ PRONOM questions:
  • How many files do I have in a PRONOM fmt/id?
    • that were ingested between date1 and date2?
• Produce sample input (CURL command) and output (JSON response)*Combine METS reader/writer work
• Modify / make new PR

Status 2015

• Initial storage service work: Pull Request
• METS reader-writer support for PREMIS: Pull Request
• PyPREMIS Repository
• Server for METS reader-writer Pull Request

Analysis 2015

• This will require improvements to METS reader-writer (metsrw) to be able to support different queries
• METS can contain multiple metadata standards - metsrw should be able to handle these in an easily-extensible way
  • Since it is the METS reader-writer, other standards should be supported as plugins of some sort
  • Prefer to use existing libraries (eg PyPREMIS) or thin wrappers around existing libraries
• By default metsrw should include PREMIS in the way Archivematica uses it and DublinCore
