Greetings, We would like to extend the origin trial for all of the Privacy Sandbox Ads APIs including: Topics, FLEDGE, Private Aggregation, Fenced Frames, Attribution Reporting, and Shared Storage.
We are sending a single intent for the extension because the rationale is shared among the APIs. *Contact emails* johni...@chromium.org, jkar...@chromium.org, pauljen...@chromium.org, *Explainer* Attribution Reporting: https://github.com/WICG/attribution-reporting-api/blob/main/EVENT.md and https://github.com/WICG/attribution-reporting-api/blob/main/AGGREGATE.md Fenced Frames: https://github.com/WICG/fenced-frame/tree/master/explainer FLEDGE: https://github.com/WICG/turtledove/blob/master/FLEDGE.md Shared Storage: https://github.com/WICG/shared-storage Private Aggregation: https://github.com/patcg-individual-drafts/private-aggregation-api Topics API: https://github.com/patcg-individual-drafts/topics/blob/main/README.md *Summary* A collection of APIs to facilitate advertising: Attribution Reporting, Fenced Frames, FLEDGE, Private Aggregation, Shared Storage and Topics. *Link to “Intent to Experiment” blink-dev discussion* Attribution Reporting: https://groups.google.com/a/chromium.org/g/blink-dev/c/jEnNpideO1Y/m/nlEDdjmnCgAJ Fenced Frames: https://groups.google.com/a/chromium.org/g/blink-dev/c/y6G3cvKXjlg/m/DSNrBtxyAgAJ FLEDGE: https://groups.google.com/a/chromium.org/g/blink-dev/c/0VmMSsDWsFg/m/_0T5qleqCgAJ Private Aggregation: https://groups.google.com/a/chromium.org/g/blink-dev/c/576sXtXNeCA Shared Storage: https://groups.google.com/a/chromium.org/g/blink-dev/c/jDx8z5a6ovk/m/H6w1UO-uBAAJ Topics API: https://groups.google.com/a/chromium.org/g/blink-dev/c/oTwd6VwCwqs/m/jPkW3T-mCgAJ Unified OT Thread: https://groups.google.com/a/chromium.org/g/blink-dev/c/Vi-Rj37aZLs/m/wzeBWfxxEgAJ *Goals for experimentation* Unchanged. *Experimental timeline* We'd like to extend the origin trial for 3 additional milestones, with the extension starting in 113 continuing through Chrome 115. The experiment is therefore running from Chrome 101 through 115. We previously requested an extension from Chrome 110 - 113 here <https://groups.google.com/a/chromium.org/g/blink-dev/c/gpmaOi3of_w/m/SyMclFhMAAAJ> . *Any risks when the experiment finishes?* The unified origin trial is only available for a subset of Chrome users, and requires developers to perform feature detection to use the APIs. *Reason this experiment is being extended* We received feedback from developers resulting in the need for continued testing and addressing several points of feedback that required changes to the APIs. The extension will allow the ecosystem more time in stable channels to continue their experiments. We additionally added individual isolated experiments for each of the Privacy Sandbox APIs, an extension will allow us to understand individual metrics outside of our existing unified experiment These improvements include, but are not limited, to the following: Attribution Reporting - Various bug fixes & utility improvements - Test cross app and web measurement - Additional debugging capabilities including source success debug reports <https://github.com/WICG/attribution-reporting-api/blob/main/verbose_debugging_reports.md#source-success> Fenced Frames - Limited feedback so far - FencedFrameConfig <https://github.com/WICG/fenced-frame/blob/master/explainer/fenced_frame_config.md> API surface and supporting size for FLEDGE <https://github.com/WICG/turtledove/pull/417> - reportEvent dev tools support, support for ARA <https://github.com/WICG/turtledove/blob/main/Fenced_Frames_Ads_Reporting.md#support-for-attribution-reporting> and for component ads <https://github.com/WICG/turtledove/issues/332#issuecomment-1416224808> FLEDGE - Improve latency (e.g. parallelization of FLEDGE auction support, more timeout support, more latency reporting) - Origin Trial Support (e.g. better integration with Private Aggregation API, k-anonymity testing, misc features) Private Aggregation (OT started in M107) - Adding support for a “context ID” to support report verification within Shared Storage worklets Shared Storage SelectURL - Replaced k-anon requirement with lower entropy limits during initial phase - Would like to have feedback from additional testers. Topics - General utility improvements (filtering is less restrictive without loss of privacy) - Performance optimizations (topics can be sent via headers in fetch and subframe navigation requests rather than creating an iframe and calling javascript) Feedback from the ecosystem will continue to influence the evolution of the APIs. *Ongoing technical constraints* Please see each API's initial Intent to Experiment. *Will this feature be supported on all five Blink platforms supported by Origin Trials (Windows, Mac, Linux, Chrome OS, and Android)?* Please see each API's initial Intent to Experiment. *Link to entry on the feature dashboard* Attribution Reporting: https://chromestatus.com/feature/6412002824028160 Fenced Frames: https://chromestatus.com/feature/5699388062040064 FLEDGE: https://chromestatus.com/feature/5733583115255808 Private Aggregation: https://chromestatus.com/feature/5743412790689792 Shared Storage: https://chromestatus.com/feature/6256348582903808 Topics: https://chromestatus.com/feature/5680923054964736 Unified Feature Dashboard: https://chromestatus.com/feature/5100526168440832 -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
