title: Inserting data with OData in atom format
body: <p>Odata is a new thing for me and I'm trying getting in deep with it. So I'm trying insert data using OData protocol in atom format and using a rest client. So I've created the following http Post request:</p>
  
  <pre><code>POST /HelloOdata/library.xsodata/books HTTP/1.1
  Host: coe-he-55:8010
  Authorization: Basic xxxxxxxxxxxxxxxxxxxxx
  DataServiceVersion: 1.0
  MaxDataServiceVersion: 2.0
  accept: application/atom+xml
  Content-Type: application/atom+xml
  Cache-Control: no-cache
  Postman-Token: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  
  &lt;?xml version="1.0" encoding="utf-8"?&gt; 
  &lt;Entry xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices"
      xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" 
      xmlns="http://www.w3.org/2005/Atom"&gt;
    &lt;title type="text"&gt;books&lt;/title&gt; 
    &lt;author&gt; 
      &lt;name /&gt; 
    &lt;/author&gt;
          &lt;link href="books('Test_post')/Author" rel="http://schemas.microsoft.com/ado/2007/08/dataservices/related/Author" title="Author" type="application/atom+xml;type=entry"/&gt;
    &lt;category term="HelloOdata.library.booksType"
        scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" /&gt; 
    &lt;content type="application/xml"&gt; 
      &lt;m:properties&gt; 
        &lt;d:title&gt;Test_post&lt;/d:title&gt;
        &lt;d:ISBN&gt;ISBN_POST&lt;/d:ISBN&gt;
        &lt;d:editions&gt;2&lt;/d:editions&gt;
      &lt;/m:properties&gt; 
    &lt;/content&gt; 
  &lt;/Entry&gt;
  </code></pre>
  
  <p>and as a response I've got: The serialized resource has an missing value for member 'title'.</p>
  
  <p>Well my table books has only three properties which are title, ISBN and editions precisely those one I'm trying insert through this statement. So, do you have any idea what can be wrong in it? </p>
  
  <p>Thank you
