Existing Module Evaluation

ALL

  • @Maccabee Levine created a spreadsheet

    with some information like age of repository on existing modules which could be used to see which modules need review. Julian also had the idea in slack to use sonar metrics to decide which modules get picked.

  • mod-ebsconet and ui-export-manager has been chosen to be first modules.

  • Criteria is being drafted at Create WIP criteria doc for existing module evals by maccabeelevine · Pull Request #98 · folio-org/tech-council

  • @Olamide Kolawole coordinating first review. @Ingolf Kuss will start review this week of backend module. He has offered to help train someone. Conversation to continue on internal Slack channel

Selection of module reviewers by co-chairs : @Florian Gleixner +. @Ingolf Kuss people who volunteer and have not done it before. Need additional assigned, others moved to current module (these will be assigned once the modules are ready.)
Perform evaluation

Environment Variables Policy

 

https://folio-org.atlassian.net/wiki/spaces/TC/pages/1319141429

Remove “Defensive validation” because the implementation cost may too high.

Passwords/Keys: Completely redact them for security reasons. Sysops can see them in Rancher, or when logging into the container and listing the env.

2025-11-10 11:14:29 Craig McNally: I will add a link to the Security Team wiki space too so this is easier to find in the future

2025-11-10 11:43:49 Wayne Schneider: Sorry, need to step away, BRB

2025-11-10 11:44:51 Matt Weaver: When this gets added to the evaluation criteria, it’d be really helpful to include a link to the standardized naming convention docs, too
Day, Kevin:👍

2025-11-10 11:45:11 Wayne Schneider: back

2025-11-10 11:48:54 Matt Weaver: Borderline useless comment: Personally, I’m not a fan of FOLIO declared or first party. I don’t have a better idea, though 😄

 

 



Topic Backlog

Decision Log Review

All

Review decisions that are in progress.  Can any of them be accepted?  rejected?

Translation Subgroup

All

Since we're having trouble finding volunteers for a subgroup, maybe we can make progress during a dedicated discussion session?

Communicating Breaking Changes

All

Currently there is a PoC, developed by @Maccabee Levine, of a utility to catalog Github PRs that have been labeled with the "breaking change" label. We would like to get developer feedback on the feasibility of this label being used more often, and the usefulness of this utility. 

Officially Supported Technologies - Upkeep

All

Previous Notes:

  • A workflow for these pages. When do they transition from one state to another. Do we even need statuses at all ?

Stripes architecture group has some questions about the Poppy release.

Zak: A handshake between developers, dev ops and the TC. Who makes that decision and how do we pass along that knowledge ? E.g. changes in Nodes and in the UI boxes. How to communicate this ? We have a large number of teams, all have to be aware of it.  TC should be alerted that changes are happening. We have a couple of dedicated channels for that. Most dev ops have subscribed to these channels. How can dev ops folk raise issues to the next level of community awareness ? There hasn't been a specific piece of TC to move that along.

Craig: There is a fourth group, "Capacity Planning" or "Release Planning". Slack is the de facto communication channel.  There are no objections to using Slack. An example is the Java 17 RFC. 

Craig: The TC gets it on the agenda and we will discuss it. The TC gets the final say.

Marc Johnson: We shouldn’t use the DevOps Channel. The dev ops folks have made it clear that it should only be used for support requests made to them.

Jakub: Our responsibility is to avoid piling up technical debt.

Marc: Some set of people have to actually make the call. Who lowers the chequered flag ?

Craig: It needs to ultimately come to the TC at least for awareness. There is a missing piece. Capacity Planning needs to provide input here. 

Marc: Stakeholders / Capacity Planning could make that decision. Who makes the decision ? Is it the government or is it some parts of the body ?

Marc: the developers community, the dev ops community and sys ops are involved. For example the Spring Framework discussion or the Java 17 discussion. But it was completely separate to the TC decision. It is a coordination and communication effort.

Marc: Maybe the TC needs to let go that they are the decision makers so that they be a moderating group.

Jakub: I agree with Marc. But we are not a system operating group. Dependency management should be in the responsibility of Release management. There are structures in the project for that.

Jason Root: I agree with Jakub and with Marc also. Policies should drive operational/release/support aspects of Folio.

Jason Root: If the idea of “support” is that frameworks are supported, then of course the project should meet that.

Marc Johnson
Some group needs to inform OleksAii when a relevant policy event occurs.
These documents effectively ARE the manifestation of the policy.

Craig: This is a topic for the next Monday session.

Craig to see if Oleksii Petrenko could join us to discuss the process for updating the officially supported technologies lists.



Dev Documentation Visibility

All

Possible topic/activity for a Wednesday session:

Discuss/brainstorm:

  • Ideas for the type of developer-facing documentation we think would be most helpful for new developers

  • How we might bring existing documentation up to date and ensure it's consistent 

  • etc.

API linting within our backend modules

All

https://folio-project.slack.com/archives/CAQ7L02PP/p1713343461518409



Hello team, I would like to discuss API linting within our backend modules. Some time ago, we transitioned our linting process from Jenkins to GitHub Actions as outlined in https://folio-org.atlassian.net/browse/FOLIO-3678. I am assuming that this move was done via some technical council decision. Please correct me if I'm wrong.
In my observations, I've found two problems:

  1. Schema linting does not occur if the schemas are in YAML format.

  2. There are issues with resolving some deeper references during API linting.

Although I'm unsure about how to improve the existing linting implementations within Folio, I propose to consider an open-source solution that handles OpenAPI linting effectively and allows us to define custom rules. For your reference: https://stoplight.io/open-source/spectral A test of this solution can be found in this PR: https://github.com/folio-org/mod-search/pull/567. The same PR also provides an example of custom rule definition: https://github.com/folio-org/mod-search/pull/567/files#diff-d5da7cb43c444434994b76f3b04aa6e702c09e938de09dbc09d72569d611d9ab.Also, by employing 'Spectral', I discovered AsyncAPI (https://www.asyncapi.com/en), an API design tool similar to OpenAPI but for asynchronous interactions. I suggest that we consider using AsyncAPI in FOLIO to generate documentation for Kafka interactions.



PR Templates

All

https://folio-project.slack.com/archives/CAQ7L02PP/p1713445649504769

Hello team, Small request to consider.
Regarding pr templates.

  1. From my perspective, pr template is not good idea. Even the biggest open source projects that are contributed by many people don't have any pr template. Currently what we have for acq modules https://github.com/folio-org/mod-orders-storage/blob/master/PULL_REQUEST_TEMPLATE.md

  2. These pr template is inconsistent in different teams.

What I suggest is that, pr template shouldn't be any instructions, because most developer who are creating pr have already understand the rules. If we put just two section into template, it will encourage developers to write more about their work and that lead to knowledge  sharing among developers.

Proposed Mod Kafka

All

https://folio-project.slack.com/archives/CAQ7L02PP/p1714471592534689

Mike Taylor

Proposal. If and only if a FOLIO instance is running Kafka, it should insert and enable a module called mod-kafka, which consists entirely of a module descriptor that says it provides the interface kafka. The purpose is so that other modules can use the standard <IfInterface> and similar tools to determine whether they should attempt Kafka operations. Rationale: the FOLIO ILS depends absolutely on Kafka, but other uses of the platform will not. One such example: a dev platform that includes only mod-users, used as a source of change events for Metadb.
