Agenda

Day 1 (Wednesday 22nd of September)

Topic	Level	Start time
What is Eiffel and why? An introduction to Eiffel Slides Video Speaker: Kristofer Hallén	Beginner	09:00
Getting started A practical guide on how to get started with Eiffel Slides Video Speaker: Magnus Bäck	Beginner	09:30
Break		10:30
The Eiffel landscape An overview of all the different components in the Eiffel community Slides Video Speaker: Mattias Linnér	Beginner	11:00
Changes in the Paris and Lyon editions of the protocol Since the last summit one new Eiffel edition has been published (Paris) and another one is on its way out the door (Lyon). This session walks through which changes have been made. Slides Video Speaker: Emil Bäckmark	Intermediate	11:30
Lunch		12:00
Technical Committee updates What has happend in the Technical committee since last time? Slides Video Speaker: Emil Bäckmark	Beginner	13:00
Maintainer role What is the maintainer role, what are its tasks and responsibilities Slides Video Speaker: Emil Bäckmark	Beginner	13:30
New routing key standard Sepia has recently been updated to standardize what RabbitMQ routing keys (topics) should be used when publishing events. This'll enable consumers to set up narrower subscriptions and not have to throw many of the received messages. See github.com/eiffel-community/eiffel-sepia#9. Slides Video Speaker: Magnus Bäck	Beginner	14:00
Break		14:30
What's cooking in the community? Many of us have Eiffel-related tools or integrations in the works. This hour is dedicated to 5–10 minute talks for showcasing ideas and things that aren't ready for a full demo or session but deserve to be shared for spreading awareness and to collect early feedback. We'll schedule these talks ad hoc but to make things easier we encourage you to contact eiffel-tc@googlegroups.com ahead of time and let us know about your talk. Fatih Degirmenci: Eiffel GitHub actions (video) Niklas Aronsson: Eiffel visualizations at Axis (slides, video) Magnus Bäck: Exposing logs from ancillary activities (slides, video) Moderator: Emil Bäckmark	Intermediate	15:00

Day 2 (Thursday 23nd of September)

Topic	Level	Start time
Eiffel vs CDF SIG Events protocol on Cloudevents What is the CD Foundation (CDF) and how does the protocol under way by its SIG events relate to Eiffel? Slides Video Speaker: Mattias Linnér	Advanced	09:00
eiffel-broadcaster Jenkins plugin A walkthrough of the features of the eiffel-broadcaster Jenkins plugin. Slides Video Speaker: Magnus Bäck	Intermediate	09:30
Event SDKs Open source libraries, or SDKs, for working with Eiffel events is missing for most languages. We'll talk about the available SDKs, how they differ, and discuss how we want these SDKs to work. Slides Video Speaker: Magnus Bäck	Intermediate	10:00
Break		10:30
Accessing an event repository Most Eiffel deployments have a centralized event repository for accessing past events. What options are there and how do they differ? Slides Video Speaker: Tobias Persson	Intermediate	11:00
Discussion: Event type categorization Event types in Eiffel can be categorized in many different ways. Sepia makes an attempt, as does REMReM. Is it relevant to have a single such categorization, and if so, what would it look like? Slides Video Moderator: Mattias Linnér	Intermediate	11:30
Lunch		12:00
Discussion: Source change events The two Eiffel events for modelling source code changes, SCC and SCS, create some challenges when attempting to use them to model a Git DAG. Let's talk about the improvement proposal made in github.com/eiffel-community/eiffel#261. Slides Video Moderator: Sven Selberg	Advanced	13:00
Discussion: Using Eiffel to implement event-triggered pipelines While Eiffel could be used just for traceability of existing pipelines it's also well-suited for actual triggering of pipeline tasks. What what are the challenges when doing this? How do you deal with error when there's no single entity that determines the pipeline graph and is responsible for its execution? Slides Video Moderator: Magnus Bäck	Intermediate	14:00
Break		14:30
Discussion: Extracting common structures Today, all Eiffel events have their own entirely independent schemas. And yet, surely everyone assumes the `meta` key's contents to be the same across all events. There are other keys whose values effectively have the same schema across more than one event type. Is this the best we can do or should we strive to change this and extract common pieces into external structures that we can reference in schema files?
