NO matching global declaration for validation root

INVALID_METADATA_DATA: invalid metadata data: Element ‘mrss’: No matching global declaration available for the validation root. at line 1 [ update transformXslt 1234 ]

I am getting the above error while uploading this xml data for my media entry … Can anyone help me resolving this error and tell me a way to upload custom metadata to entry through kaltura api.

This is my xml data.

Hello @Arpit1596,

Here’s an example:

<mrss xmlns:xsd="" xmlns:xsi="" 

                            <customData metadataProfileId="PROFILE_ID" metadataProfile="PROFILE_NAME">
                                            <FIELD_NAME>some value</FIELD_NAME>


As for using the API, see

Thanks for the help.
