data-vocabulary.org to schema.org breadcrumb conversion to avoid Google search console error

[cinolas]

Like many of you Im sure I'm receiving Google search console errors about my site using the soon to be deprecated data-vocabulary.org schema. Google will no longer support it as of April 6 2020.

How would I go about converting osCommerce 2.3.4 BS to use schema.org instead? There are many pages online showing the differences, which I'm sure I could figure out, but the new schema requires additional data like the position of the item in the breadcrumb. This needs to be calculated to be included.

Has anyone done this already?

I'm digging around to see if I can manage the change but pointers would be greatly appreciated.

Cheers!

I did it with the breddcrumb code from Phoenix  just yesterday .... seems to work! Google seems happy for most pages!

Thanks, I will look into it.

It's actually pretty simple:

Simply change the markup in /includes/classes/breadcrumbs.php
And you can add the <meta itemprop="position" content="3"> part, use ($i+1) for the content and your get the right position.

I recommend you use this content module:

https://github.com/gburton/CE-Phoenix/blob/master/includes/modules/header_tags/ht_breadcrumb_schema.php

Off course you also need to use the changed class:

https://github.com/gburton/CE-Phoenix/blob/master/includes/classes/breadcrumb.php

And the header module:

https://github.com/gburton/CE-Phoenix/blob/master/includes/modules/content/header/cm_header_breadcrumb.php

Since you are apparently not on Phoenix / older Community Editions - you might have to add more changes.

In addition to the links azpro provided, adding the file

https://github.com/gburton/CE-Phoenix/blob/master/includes/modules/content/header/templates/tpl_cm_header_breadcrumb.php

and installing the module via Module > header tags solved the issue for my 2.3.4 BS installation. 

Thank you all,

One question though, google's rich results seem to prefer the tag 'SKU' instead of OsC's 'model'. Where can we find the piece of code in breadcrumb to change this? 

Thank you
