        <ol type="1" id='rerumPrinciples'>
            <li><strong>As RESTful as is reasonable—</strong>accept and respond to a broad range of requests without
                losing the map</li>
            <li><strong>As compliant as is practical—</strong>take advantage of standards and harmonize conflicts</li>
            <li><strong>Save an object, retrieve an object—</strong>store metadata in private (__rerum) property, rather
                than wrap all data transactions</li>
            <li><strong>Trust the application, not the user—</strong>avoid multiple login and authentication
                requirements and honor open data attributions</li>
            <li><strong>Open and Free—</strong>expose all contributions immediately without charge to write or read</li>
            <li><strong>Attributed and Versioned—</strong>always include asserted ownership and transaction metadata so
                consumers can evaluate trustworthiness and relevance</li>
