-------------------------------------
Hi Miki,
??thanks again for your input.??
No Problem ;o)
??It is interesting that the OData Specification does not mandate the use of
m:type in simple properties.??
Just to be sure I took a look into and
[there|http://www.odata.org/documentation/atom-format/#61111_Entity_Property_as_a_datapropertyName_Element]
it is defined (for version 2) as:
{noformat}
6.1.11.1. Entity Property as a data:[propertyName] Element
…
The data:[PropertyName] element MAY include a metadata:type attribute to
specify the type of the simple- or complex-typed instance.
…
{noformat}
??Should this be raised as a defect/enhancement???
I suggest to open a new JIRA issue from the type _enhancement_.
Because IMHO it is not a bug but a feature.
??How soon can this type of functionality be added to Olingo???
Good question, but I have to take a deeper look into the implementation before
I really can answer this.
Kind regards,
Michael

>
> Hello,
> I am migrating an odata service from odata4j to olingo. During creation of
> single odata entries or odata feeds, odata4j allows you to specify the type
> of each property element. How can this be achieved in olingo? See attached
> xml feeds for an entry generated in odata4j and one generated in olingo.
> We generate the metadata at runtime using custom database queries and in
> odata4j we can cache the metadata document to avoid having to rebuild it
> every time a request is received. How can metadata be cached between requests
> in olingo? Following the simple read example on the olingo website, we use an
> ODataServiceFactory to create a service using method
> createODataSingleProcessorService(), but these methods are invoked during
> each request.
> Cheers
