Implement the attributes system

[rensPols]

Current idea:

Scope

• global
  • websites (key, name)
    • storeviews (key, name)

*Can differ per scope

Attributes

• key
• name*
• dataType
• Required / nullable
• Default value*
• Scope level [global, website, storeview]
  • The deepest level that it can have different values for.

Attribute sets

• attribute_set_key: String
• name*: String
• attributes: List (this is recursive)
  -- attribute_key: String
  -- folder: Map<String, String|List>
  --- name*: String
  --- attributes: List (this is recursive)

Attribute (set) types

• Product attributes / attribute sets
• Category attributes / attribute sets
• Page attributes / attribute sets

Implementation within MongoDB

Every request needs to provide a scope.
When you request an attribute with a scope, the server fetches all the data of the scope (e.g. storeview_a -> fetches storeview_a, websiteOfStoreviewA, Global) (here presides a caching oppertunity).
And combines that all together by overlapping all the data and prioritises the storeview data over the website data over the global data.

Collection names

Attributes

• product_attributes (x1) global data
• category_attributes (x1) global data
• page_attributes (x1) global data

How different scope collection names work

• x1
  • x1_websiteKey (x2) website data
    • x2_storeviewKey storeview data

Attribute sets

• product_attribute_sets
• category_attribute_sets
• page_attribute_sets
