This page contains an overview of features that are currently present in one or both of the frameworks, plus features that we would like to add.
.NET version
| Feature | Implementation in DD4T | Implementation in DXA | Preferred solution | Discussion |
|---|
| ViewModels | - Attribute-driven
- Possible to add your own attributes
- Pages + ComponentPresentations
- Two-step approach (1. deserialize into page/cp, 2. map properties to strongly typed model)
| - Attribute-driven
- Not possible to add your own attributes
- Properties find matching fields in an embedded field
- ComponentPresentations only
- Two-step approach
| To be decided | Ideal is to deserialize directly from DD4T JSON into view model. |
| Caching | - Open, extensible
- Event-based and time-based invalidation
| - Closed
- Time-based expiration
| DD4T? | We need an overall caching layer for the entire microservice (because SDL doesn't offer this at all) Enterprises want to decide on a caching solution themselves |
| Controllers | | | To be decided | |
| Navigation | | - navigation.json page published from Root SG
- Based on site structure
- Simple (SG and Page title based) and Localizable (based on component content) implementations
- Logic in TBB
- Example Controller, Models and Views to implement Top nav, context nav, breadcrumb, sitemap, google sitemap
| DXA? | |
| Labels/Resources | | - 1 labels JSON 'file' published per module (avoids key clashes across modules) as part of Publish Settings page publish
- Key-value pair and bespoke schema implementations supported
- Multiple labels components per module possible
| ? | |
| Configuration | | - Implemented in the same way as Labels/Resources
| | |
| Preview | | Not implemented | DD4T | |
| XPM | - Linked to ViewModels
- Helper called from views to render tags
| - Helper called from views to render tags
- View output is loaded in XML document and manipulated with XPath
| DD4T | Faster, no requirement to have well-formed view output |
| Modules | | - Standard structure for CM and CD for packaging modules
| | |
| HTML Design | | - Option to build and distribute HTML design from CMS
- Also possible to deploy as part of web app
