             Project: Olingo
          Issue Type: Question
          Components: MISC, odata2-annotation, odata2-core, odata4-server
    Affects Versions: V2 2.0.3

This question is about the support for attachments uploading and downloading via Olingo Service ( Olingo V2 2.0.3 ). I have gone the olingo docs but didn't find any clue on how to provide support for uploading and downloading of attachments using olingo . 

Does olingo supports this functionality ? If olingo supports , how to implements this ? 

Following are some basics which i came to know by debugging the core library :
-> Media type support : We can provide support for custom content types by overriding the method getCustomContentTypes() in processor class. 
-> Implementation : we can implement createEntity as following in processor class :

@Override
	public ODataResponse createEntity(PostUriInfo uriInfo, InputStream content, 
	String requestContentType, String contentType) throws ODataException { ... } 
	
	But here content is giving the requestBody , not actual file/attachment.

Note : Here the support for attachments means - ex : in case of Rest , CXF provides some api which can be seen in following snippet :

	@POST
	@Consumes( {MediaType.MULTIPART_FORM_DATA })
	@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
	public Response create(@Context HttpHeaders httpHeaders, @Context UriInfo uriInfo,
			MultipartBody multipartBody)

Here @Consumes media type provides consumption of multipart formdata and MultipartBody parameter can give us the attachments. 

Similar to above , Does Olingo V2 2.0.3 provides any API ?How can we implement the support for attachments in Olingo V2 2.0.3 ? Please share us an example !
