Using the content spec REST entities often involves looking up specific metadata nodes. It would be nice if the constant metadata nodes had names in a common library like RESTv1Constants so we could write code like

String title = "";
for (final RESTCSNodeCollectionItemV1 csNode : spec.getItem().getChildren_OTM().getItems()) {
    if (csNode.getItem().getNodeType() == RESTCSNodeTypeV1.META_DATA &&
            csNode.getItem().getTitle().equals(RESTv1Constants.CONTENT_SPEC_METADATA_TITLE)) {
        title = csNode.getItem().getAdditionalText();
        break;
    }
}
