looking for guidence on registration of deprecation trial #8

Hi,

I have a couple of question about registration of deprecation trial

Use case: I have couple of website. For example, I have a.web.com, b.web.com, c.web.com etc.. All those website are under the same domain - web.com. And I have iframe.com. iframe.com will be embedded in those website as an iframe. All those xxx.web.com website will postMessage data object to the iframe.com, and iframe.com will save the data object into the localStroage. And user will visit iframe.com to see all data object which are collected from a.web.com b.web.com and c.web.com etc.

In this case, in order to register in the deprecation trial.

  1. What is the correct "Web Origin", is it "https://web.com"? because the subdomain will change, but domain will always be web.com, so what should I put here?
  2. Should I select those two options? 
    Third-party matching. The token will be injected by script on other origins.
I need a token to match all subdomains of the origin.
  3. Which website should be the top-level site, like I should put the <meta> tag and token in which website's html. The iframe.com or xxx.web.com?
  4. Once I enroll into the deprecation trial, If want to access the localStorage, should I just calling window.localStroage.getItem(key), just like we do not parationing the storage before. Or is there any other steps needed, like calling the Storage Access API (e.g requestStorageApi())?

Thank you so much for the guidence!

Since you manage the top-level origin, you probably want to generate a token for web.com that matches all subdomains and isn't third-party. If you're in the trial and properly include the token, all iframes loaded on that page will have unpartitioned storage.

Going to close this as resolved, given the lack of any follow up responses.
