928 -Reference metadata defined by a Metadataflow or a MetadataProvisionAgreement are exchanged within reference metadatasets, which are maintainable and thus for actions behave like structural metadata (artefacts): When interacting with SDMX Rest web services, the HTTP action verbs GET, PUT and POST are used to indicate the intended action per web request. Consequently, different actions cannot be bundled and executed with “transactional ACIDity”. Note that metadatasets retrieved using the HTTP header “Accept-Language” may contain only partial languages, and thus should be marked with its *isPartialLanguage* property set to true. Submitting such a partial metadataset to update an SDMX storage system will only add or update the included languages but not change other languages.
