SAPUI5 ODataModel metadata $format=xml

i am trying to connect sapui5/openui5 ODataModel to an odata-server. I want to use a nodejs server with package simple-odata-server. Unfortunately this odata server provides metadata only in xml-format. But sapui5 tries to load metadata in json-format.

Before i switch to another odata server, i want to check, wether sapui5 can load metadata in xml-format. I tried to create the model with several parameters, but ODataModel still tries to load metadata as json.

var oModel = new ODataModel("/odata", {
    "metadataUrlParams": "$format=xml",
    "json": false
});

Does anybody know, wether i can switch to $format=xml

Thanks in advance, Torsten

Not a solution to your specific problem, but Helmut Tammen has developed a nodejs OData server specifically for use with SAPUI5: github.com/htammen/n-odata-server You may want to try this – Qualiture
the n-odata-server project seems to be a goot alternative. i will try it. – Torsten

As far as I know the OData protocol metadata is always provided as XML, never seen metadata in JSON format. Also my n-odata-server Qualiture mentioned in the comment above does it. But I never had problems with SAPUI5. It requests the metadata, gets the xml stream and works with it.

Since the metadataUrlParams parameter is of type map I'd suppose it would at least do what you intend like this:

var oModel = new ODataModel("/odata", {
  "metadataUrlParams": {
    "$format": "xml"
  }
});
