Michael Bolz commented on OLINGO-32:
------------------------------------

Hi together,

the past few days I committed the changes in the {{Edm*}} annotation within the 
{{olingo-odata2-api-annotation-incubating}} module (see branch 
'PocEdmAnnotationsExtension: ).

Currently their exists redundant annotations which are used by the annotation 
extension or the JPA extension.

This are:
* {{Facets}} / {{EdmFacets}}
* {{FunctionImports}} / {{EdmFunctionImport}}
* {{Parameter}} / {{EdmFunctionImportParameter}}

Currently not used by the edm annotation extension is {{Documentation}}. It is 
possible to remove this annotation?
IMHO we for consistence we should only use the {{Edm*}} annotations. 
@Chandan: You are familiar with the JPA extension, hence could you please take 
a look into the JPA parts whether it is possible to replace above mentioned 
annotations with their {{Edm*}} counterpart?

Kind regards,
Michael

> The idea is to create your model as POJOs which then can be annotated with 
> special {{@EdmXXX}} (Java) annotations to define the EDM for an OData Service.
> Based on these annotation then the {{edmx}} document ({{$metadata}}) can be 
> generated as well as a generic {{Processor}} ({{ODataSingleProcessor}}) for 
> e.g. {{JSON}} can be written.
> As initial contribution and starting point for discussions about this feature 
> a branch with name {{PocEdmAnnotationsExtension}} is created with a basic 
> Proof of Concept.
