[SEO / Structured Data] Define main taxon for usage in breadcrumbs

[fthobe]

@rahulsingh321

Desired Behavior
Considering Starter Frontend Issue #130

Currently breadcrumbs are not necessarily generated correctly as multiple taxons can be picked to load them in the store front.

Quoting @tvdeyen

Every shop I worked with has a different understanding of what the main taxonomy (most of the time referred to as "Category") is. Some refer to as the "Storefront" taxonomy, some call it "Navigation", etc. I can see that there is an urge for at least something that is been used as the main product category.

We could make it configurable and default to a taxonomy with a "Category" name or add a flag to the taxonomies table (ie. main_category).

I am open to suggestions.

If introducing a main_taxon is ok for everybody that's fine for me and we could implement that.

What about a flag on the taxonomy, similar to default_for_breadcrumbs. "Main" doesn't have a good semantic IMHO.

[fthobe]

Hi @kennyadsl do you mean that a taxon is flagged as a primary taxon for all products related? Sorry I am trying to understand your approach better as currently the issue is that there are too many taxons possible taxons to reliably render breadcrumbs and I feel we just shift the problem instead of solving it if we don't create a simple 1 product has many taxons but one primary taxing relation to generate the breadcrumbs instead of creating a scenario where multiple primary taxons can be associated to one taxon. I found what @tvdeyen wrote spot on and felt it was a good comment. Can we settle for that approach?

[fthobe]

@kennyadsl default_for_breadcrumbs is a little long, is breadcrumb_taxon fine?

[kennyadsl]

use_for_breadcrumbs or breadcrumbs_source?

[fthobe]

Man, whatever makes you happy and creates something that is merged.

Follow the breadcrumbs to reach the PR... 🍞

@rahulsingh321 use breadcrumbs_source
@kennyadsl what label in the admin interface?

You get this started by complaining for the long column name! 😆
For breadcrumbs_taxon, my point is that you are adding the column to the taxon table, it's useless to repeat that that value refers to a taxon. You'll have taxon.breadcrumb_taxon, which is redundant.

I'm ok with whatever name, just use your common sense.

Honestly we went for a selector.
