GREI 3: HDV Task - Improve OAI-PMH Harvesting

[cmbz]

Overview

"Our proposed project will significantly improve the widely-used Harvard Dataverse repository to better support NIH-funded research. A critical measure of the GREI program’s success is to standardize the discoverability across generalist repositories.

To help with this, we propose to improve the existing harvesting functionality in the Dataverse software based on the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) standard, and coordinate with other repository packaging standards to share or move metadata and data. Dataverse already supports the Bags as defined by the Research Data Alliance (RDA) Research Data Repository Interoperability Working Group.

Here we proposed to improve the support for Bags, test it for NIH-funded datasets, and explore and define the appropriate standard to use to move the metadata and data across generalist repositories This will help with a sustainable and succession plan - if one repository cannot support anymore a specific dataset, it will allow to easily move the dataset to another repository without losing any information about the dataset."

Harvesting Issues (Year 3)

In Progress

• Change Dataverse / Dublin Core mapping to improve OAI-PMH harvesting dataverse#8129
• Harvest metadata from SRDA dataverse.harvard.edu#243 - essentially done (we have harvested their metadata and their datasets are searchable by our users). we are keeping the issue open because we asked the devs at SRDA to improve something on their end, so this is for us to remember to check on the progress.
• Feature Request/Idea: Sanitize languages controlled vocabulary values dataverse#8243 - complete
• Re-harvesting datasets from Roper Center dataverse.harvard.edu#204 - this is pending on Roper devs. fixing something on their end. We have reestablished contact and communicated what the issues are.
  • https://help.hmdc.harvard.edu/Ticket/Display.html?id=330637
• Re-harvest from Borealis Repository dataverse.harvard.edu#172 - ongoing effort
• https://help.hmdc.harvard.edu/Ticket/Display.html?id=322153
• Harvested dataset display is broken on develop branch dataverse#10611
• Refactor reindexing of harvested datasets  dataverse#10734

Complete

• Revisit/reimplement the concept of a "Harvested file".  dataverse#8629
• Harvest: Do not list a set as available in ListSets until it has been successfully exported at least once. dataverse#3322
• Harvesting: OAI sets are not updated when datasets are deleted. dataverse#8005
• Purge all the stale Nesstar harvested dataverses in production dataverse.harvard.edu#153
• Unable to create harvesting client for SRDA repository dataverse#7624

• Harvest: Set export can temporarily be adversely affected by full (clean) reindex. dataverse#3437
• 3437 OAI records for datasets that still exist, but are temporarily un-indexed should not be marked deleted dataverse#10222
• Feature Request/Idea: Harvest metadata values that aren't from a list of controlled values dataverse#9992
• XML declaration missing from OAI when using oai_ddi dataverse#10329

• Add harvesting feature to handle missing controlled values dataverse#10323 - almost done (currently in QA)
• Fix redirects to the original repository for "Generic OAI Archive"-type Harvesting Clients dataverse#10254 - for the most part, the fix already exists (added to the prod. 6.1 patch - that's what made it possible to harvest from SRDA, next item on the list)

Meetings

A meeting was held on 2024/03/13 to:

• Discuss current GREI harvesting issues defined here: GREI 3: HDV Task - Improve OAI-PMH Harvesting #171.
• Discuss larger issues and spikes requiring substantive design and refactoring work and coordination
• Define a plan of action for GREI Year 3 (and ideally, Year 4) to complete the known remaining harvesting issues and any new, in-scope issues that may arise.

Action Items

The following action items were identified:

• Create an ordered list of non-Dataverse repositories that need harvesting @jggautier
• Add additional issue/RT Tickets related to harvesting to the tracking issue @jggautier
• Create list of all Dataverse installations we should be harvesting from and identify best metadata format for each @jggautier
• Re-create harvesting clients using most appropriate metadata format in order to harvest as much metadata as possible from each client, following draft policy @jggautier
• Modify policy issue to reflect discussion: Policy Question: Do we have an End-of-Life, End-of-Service policy for Harvesting feature? #100 @scolapasta
• Create "repository harvest profile" for each non-Dataverse repository that indicates the type of harvesting-appropriate metadata exports it supports. Use these profiles to inform the harvesting process for each repository. @jggautier
• Order the existing Pending issues list in order of priority @landreev
• Identify the current, remaining harvesting issues in the dataverse repo and add them to the tracking issue in a new section @cmbz

Other Work Towards Improving Harvesting

• @jggautier updated the GitHub issue at Align or merge DataCite metadata exports dataverse#5889 with a proposal for sending more metadata to DataCite

Completed

• Feature Request/Idea: Harvest metadata values that aren't from a list of controlled values dataverse#9992
• XML declaration missing from OAI when using oai_ddi dataverse#10329
• Feature Request/Idea: Harvest metadata values that aren't from a list of controlled values dataverse#9992
• Use Abacus Data Network's new server URL to harvest the installation's metadata dataverse.harvard.edu#251
• Add harvesting feature to handle missing controlled values dataverse#10323
• Fix redirects to the original repository for "Generic OAI Archive"-type Harvesting Clients dataverse#10254

[cmbz]

Status: April 2024

• @jggautier continued the March 2024 action item of re-creating harvesting clients using the most appropriate metadata format in order to harvest as much metadata as possible from each client. But he stopped due to technical issues being investigated, described at Investigate Solr performance issues (again) dataverse#10469, that are affecting harvesting.

[cmbz]

Status: June 2024

• @jggautier emailed the contacts of all repositories we've been emailing about Harvard Dataverse harvesting from their repositories. In most cases he let them know that we continue to work on challenges that prevent Harvard Dataverse from harvesting from these repositories, and in a couple of cases, such as what's described in #243, he asked about the status of related work that they are doing so that Harvard Dataverse is able to harvest from them.

[jggautier]

@landreev, @cmbz and @scolapasta, today or sometime this week I'm thinking of following up with contacts of the repositories who've emailed our support email addresses about harvesting, to let them know that we're continuing to work on improvements related to how Dataverse indexes records, and some of those improvements may affect harvesting. Most of the emails sitting in my RT queue are harvesting related:

[cmbz]

@jggautier Great thanks! When you do, please update the June status comment, too #171 (comment)
