What overlaps are there, and is there undesirable redundancy? * Do we want to be able to reference OpenTelemetry traces from Eiffel? How? * Do we want to be able to reference Eiffel events from OpenTelemetry traces? How? * See [MoM](https://hackmd.io/Geb5E36dSSupp2dsFH7izw) * 2023-11-23: Source Change Events * https://github.com/eiffel-community/eiffel/issues/261#issuecomment-1831790177 * [2023-08-31: Eiffel Protocol Discussions - Git Tags, Confidence Basis and more](https://hackmd.io/6qfORbWFQd-gPgowBhoMtg) * Magnus: Source change tagged event - https://github.com/eiffel-community/eiffel/issues/219 * Mattias: CONFIDENCE_BASIS (new event link in CLM) - https://github.com/eiffel-community/eiffel/pull/368 * also in relation to potential change of VERIFICATION_BASIS in IV * Emil: Other PRs / issues of your choice - please raise your concerns! * [2023-05-11: Source change events and tags](https://hackmd.io/fYFr6BIgTE-o2_49T7RDUQ) * When to send these events and from where? * Gerrit plugin? * Jenkins plugin? * Stand-alone SCM web hook listener? * Why do we send SCM events? * Trigger pipelines? * Visualize SCM/Git activities? * Replace the need to ask Git about the Git tree? * [2023-04-13: Expressing a confidence level for combinations of SW and HW](https://hackmd.io/dpQQOkEeQoC5yV7IpFUYOg) * We have SW that can be run on multiple types of HW. This means a SW can pass tests on one HW but fail on another and we would like to express this with confidence levels. The legal targets (subject link) for the ConfidenceLevelModified event don't seem well suited to describe HW (CompositionDefined probably being the best option). * 2023-03-16: Cancelled * 2023-02-16 * What makes the Eiffel link concept stand out and is it the only valid solution to correlate events? * The background is that in the ongoing work to define the [CDEvents](https://cdevents.dev/) protocol, the concept of “links” has not yet been accepted as the way to correlate events. This discussion aims to provide use cases and scenarios where the link model in Eiffel is favorable over for example “span IDs” á la OpenTelemetry. * [Discussion link](https://hackmd.io/nAfMMmKZRdyzJthWTwtXlg) * 2023-01-19 * Protocol issue backlog cleanup & priorities - https://github.com/orgs/eiffel-community/projects/6/views/1 * 2022-12-08 [Agenda in detail](https://hackmd.io/@eiffel-community/HJjPqfyuo) * Set the deployment event proposal, 30 mins * Define needed events and their data to be used as input for DORA metrics and prepare for a PoC on DORA metrics, 60 mins * Discuss how to handle beta (pre-1.0) event definitions, 30 mins * 2022-11-10 * Ola Söder (Axis) demoed a real-time event stream visualizer. * CDEvents/Eiffel demo from Ericsson * 2022-09-15 - First half to work on the summit agenda. - Second half to have the meta discussion about deployment events. * 2022-08-18 - 13-14: Summit preparations - 14-15: Deployment events * 2022-06-09 - Deployment events ([github.com/eiffel-community/eiffel#239](https://github.com/eiffel-community/eiffel/issues/239); see also [meetup summary](https://hackmd.io/@eiffel-community/Hy19X67P5#Deployment-events)) * 2022-03-31 * .NET SDK demo * Presentation of new file format for generating schemas and documentation ([github.com/eiffel-community/eiffel#282](https://github.com/eiffel-community/eiffel/issues/282)) * [2022-03-03 - Generating documentation and schemas from a common source](https://hackmd.io/CyrCga7eTRO3u6FymkPh_w) * [2022-02-03 - Source change events](https://hackmd.io/joh2o8eVSN2gz1eUMxl20A) * [2021-12-09 - SDKs](https://hackmd.io/aEpAat1iQgmM4C0RmNmiCg) * [2021-11-11 - Protocol workshop](https://hackmd.io/PkyXTWTNQTSqxC84COcYPg) * [2021-10-14 - Protocol workshop](https://hackmd.io/jEiLclrrTaG5tPIBvrtRfg) * [2021-09-16 - Protocol workshop](https://hackmd.io/MsyB-dOmR9W7q_HFQudFCw) * [2021-08-19 - Summit planning](https://hackmd.io/I6pzkMpoS4aVZu3795pLtQ) * [2021-05-27 - Protocol workshop](https://hackmd.io/WnhRdLZjRiyNFNHa3exvjw)
