A Meta Keys field allows you to add arbitrary pieces of information to entries identified by a user generated key. The interface resembles the section editor in that any number of keyed information could be added to an entry (interface possibly provided by the Stage extension).
The values would always be text (at least initially).
For instance, a Meta Keys field could be added to a Products
entry and then filled with this data:
- Colour: Red
- Size: 500ml
A datasource could then filter on the keys (in a yet to be determined syntax), eg. color=red
.
