--------------------------------------
Summary: Support for OpenType
Key: OLINGO-1645
URL: https://issues.apache.org/jira/browse/OLINGO-1645
Project: Olingo
Issue Type: Improvement
Components: odata4-server
Affects Versions: Version (Java) V4 5.0.0, (Java) V4 4.10.0
Reporter: Florent Albert
Currently (as of Olingo 5.0.0), support for Open Type is limited to specifying
"OpenType=true" in the EDM.
However, parsing, serialization and deserialization of dynamic properties of
open types do not work.
The goal of this enhancement is to implement full support for open types,
including:
* Ability to deserialize a request body of an entity/complex type containing
dynamic properties.
** Create (POST)/Update (PATCH/PUT) requestsÂ
** Action parameters
* Ability to serialize dynamic properties in response bodies
** Note that when $select is specified and the dynamic property does not
exist, the request should be successful and the response should contain a null
value: [OData Version 4.01. Part 2: URL
Conventions|https://docs.oasis-open.org/odata/odata/v4.01/os/part2-url-conventions/odata-v4.01-os-part2-url-conventions.html#sec_SystemQueryOptionselect]
* Ability to parse dynamic properties passed in query parameters ($select,
$filter, $orderby)
** Parsed dynamic properties should be passed down to ExpressionVisitors and
ExpressionValidators
Ambiguous types (e.g. DateTimeOffSet and String) should be resolved according
to the _odata.type_ annotation when present, the _cast_ method when present
(unsupported by Olingo at the moment) or the default logic specified here:
