1538985 - Refresh telemetry probe for MathML.

Status: RESOLVED FIXED

(Core :: MathML, enhancement)

Description

[Emilio Cobos Álvarez [:emilio]]

Igalia is going to do MathML work, and it'd be useful to have various kinds of data to be able to take informed decisions about when to deprecate stuff and such.

In order to get a baseline to measure feature usage against, we should re-enable the telemetry probe for documents using MathML.

Attachment: Bug 1538985 - Renew the telemetry for documents that contain MathML, and make it opt-out. r=janerik

There's renewed interest in MathML, see https://github.com/mathml-refresh/.

We want to have data before removing deprecated stuff, from our core MathML
implementation.

We want to measure the release population, and compare number of documents with
MathML against all top-level content documents. The comparison is meaningless if
the data is collected in a different way from the way we collect top-level
content document loads, so given that the scalar for top-level loads is opt-out,
make it match.

Gerald, I assume you're no longer interested in this probe so I've removed you from the email list, but let me know if you want to keep getting the alerts and I can add you back.

I'm always interested! 😉 But effectively I probably could not help with alerts anyway, so better for me to be off it. Thanks Emilio.

Data collection request form.

DATA COLLECTION REVIEW RESPONSE:

    Is there or will there be documentation that describes the schema for the ultimate data set available publicly, complete and accurate?

Yes. This collection is Telemetry so is documented in its definitions file [Scalars.yaml](https://hg.mozilla.org/mozilla-central/file/tip/toolkit/components/telemetry/Scalars.yaml) and the [Probe Dictionary](https://telemetry.mozilla.org/probe-dictionary/).


    Is there a control mechanism that allows the user to turn the data collection on and off?

Yes. This collection is Telemetry so it can be controlled through Firefox's Preferences.

    If the request is for permanent data collection, is there someone who will monitor the data over time?


No. This collection will expire after 6 months.

    Using the category system of data types on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 1, Technical.

    Is the data collection request for default-on or default-off?

Default on for all channels.


    Does the instrumentation include the addition of any new identifiers?

No.

    Is the data collection covered by the existing Firefox privacy notice?

Yes.

    Does there need to be a check-in in the future to determine whether to renew the data?


Yes. :emilio is responsible for renewing or removing the collection before it expires in 6 months.
