Add EmployerAggregateRating and reviewAspect

[vholland]

In schema.org 3.3, we will be adding EmployerReview as discussed in issue #1576. Some review sites allow users to write reviews based on specific aspects (e.g. employer benefits or work-life balance). In some cases, the sites aggregate ratings across multiple reviews, so readers are presented with a number like "ACME Industries rates 4/5 stars".

To help authors of these pages better express their content, I propose adding the following.

• reviewAspect: This Review or Rating is relevant to this part or feature of the itemReviewed.
  • Domain: http://schema.org/Review and http://schema.org/Rating
  • Range: Text
• EmployerAggregateRating: An aggregate rating of an Organization related to its role as an employer.

for reviewAspect, can you give a few examples? ideally real sites.

for EmployerAggregateRating, do the relevant sites always hide individual ratings eg for privacy reasons there is no call for EmployerRating?

Glassdoor allows reviewers to review salaries and employee benefits. Benefits can further be broken down into health insurance, 401(k), discounts, etc. See https://www.glassdoor.com/Benefits/Apple-US-Benefits-EI_IE1138.0,5_IL.6,8_IN1.htm

Indeed also allows reviewing salary separately from benefits. It also allows for reviewing culture, work-life balance, management, etc. See https://www.indeed.com/cmp/Amazon.com/reviews

I thought about proposing EmployerRating, but in the examples I saw, individual ratings were linked to reviews, so you could infer it was an EmployerRating. I am not opposed to adding it for completeness.

Makes sense. so the text for the aspects is, for now, likely to be based on per-site wording, unless/until broader consensus emerges...?

[vholland]

Yes. I thought about trying to create a small taxonomy of aspects, but decided it would be better to wait for some sort of consensus.

Merged into pending.

Is reviewAspect still planning on being used - think it's a good idea - but was returning a 404 on the schema.org site.

(on @scroobiustrip 's point, https://pending.schema.org/reviewAspect was there)

We should move this to core. It got used, e.g. see https://developers.google.com/search/docs/data-types/employer-rating
