I would like to put on your wishlist for one of the next CCK versions

1) Google structured data for instance layout and show all instance layout.

2) open graph meta tags

3) <link rel="canonical" href="xxx.com" />

Hi

Please check
1) Google structured data for instance layout and show all instance layout.
Google has some set of "structured data" and depend of micro data type - they have different fields. In our Joomla CCK - ypu may create any type of information. So and Micro data will different.
Most best way add micro data to jomla CCK next:
- add google micro data to show one instance: Please in every instance create 2 "text area" fields "Micro-data1" and "Micro-data2" - in these field at time instance edit - please add your micro date/
And to "show instance layout" please add these fields. 1 field you may add to "show instance layout" with instance details description, other to "show instance layout" with instance short description
- add google micro data to show all instances: You may add to "Show all instances" layout "custom field" - and there add your micro data

2) open graph meta tags
You may use our joomla social sharing module for that

3) <link rel="canonical" href="xxx.com" />
In jomla CCK you may add this also to "micro data1" field as in point1
