How to create localized asset via REST ?

How can  create a localized asset via  REST.

Considering the provided CreateAsset REST demos, the following didn't unfortunately localize the asset but it was created.

      sourceAssetAttribute = new Attribute();
        sourceAssetAttributeData = new Data();
        sourceAssetAttribute.setName("locale");
        sourceAssetAttributeData.setStringValue("Dimension:1374097578655");//  or sourceAssetAttributeData.setStringValue("en");
        sourceAssetAttribute.setData(sourceAssetAttributeData);
        sourceAsset.getAttributes().add(sourceAssetAttribute);

Thank you.
