Is it possible to "consume" metadata extensions in SAPUI5

[vulturas]

Hello everyone,

I learn ABAP RAP and have defined a metadata extension in my service.

@Metadata.layer: #CORE
@UI.headerInfo: {
  typeName: 'Handling Unit',
  title: { value: 'HandlingUnitNumber', type: #STANDARD },
  description: { value: 'HandlingUnitUsageDescription' }
}
annotate entity /#####/#####
  with 
{
  .facet: [{
    id: 'HeaderFacet',
    purpose: #HEADER,
    type: #FIELDGROUP_REFERENCE,
    targetQualifier: 'HeaderItems'
  }]
  
  .fieldGroup: [{
    qualifier: 'HeaderItems',
    position: 10
  }]
  PackagingMaterialName;
   
}

Is it possible to use/call/consume this metadata extension inside a SAPUI5 app as an addition? I read something about extensions points, but they didn't help me much 😕

Any approach or hint is appreciated. 

Kind regards

Jürgen

Your can can make use of annotations on CDS views in two ways:

• If your app is a Fiori Elements App
• If your app is a Freestyle app and you use Smart controls

I guess this is the right way. Do you have a small sample how to achieve this in a freestyle app using Smart Controls?

Sure, you can follow the Smartcontrols tutorial: https://sapui5.hana.ondemand.com/#/topic/64bde9a8879d4f418e2849f7285dd757

what you are trying to get?

normally you don't need to do anything.

I have an freestyle UI5 app. And I was told that it's possible to show Fiori Elements inside the UI5 app. This could be achieved via MDE.

just put the smart control in your app, just like other control, it will consume metadata/annotation automatically if you have it.
