  sub:assertion dcterms:description """<p>This template allows you to create Rosetta Statements following the metamodel described in \"Rosetta Statements: Simplifying FAIR Knowledge Graph Construction with a User-Centered Approach\".</p>

<p><strong>Rosetta Statements</strong> model the structure of simple English natural language statements rather than attempting to represent a mind-independent reality. They prioritize:</p>
<ul>
<li><strong>Cognitive Interoperability:</strong> Easy to understand for domain experts</li>
<li><strong>Findability:</strong> Supports search without requiring SPARQL knowledge</li>
<li><strong>Semantic Interoperability:</strong> Standardized patterns for each statement type</li>
<li><strong>User-Centered Design:</strong> Reflects natural language structure</li>
</ul>

<p><strong>Key Features:</strong></p>
<ul>
<li><strong>N-ary Support:</strong> Handle statements with multiple objects (not just binary relations)</li>
<li><strong>Dynamic Labels:</strong> Display as natural language sentences in user interfaces</li>
<li><strong>Versioning Support:</strong> Track changes and editing history</li>
<li><strong>Metadata Rich:</strong> Include confidence levels, negation, context, and provenance</li>
<li><strong>Wikidata Integration:</strong> Use Wikidata terms for immediate usability</li>
</ul>

<p><strong>Statement Structure:</strong></p>
<ul>
<li><strong>Subject:</strong> The main entity the statement is about</li>
<li><strong>Predicate:</strong> Captured by the statement type/class</li>
<li><strong>Objects:</strong> Up to 4 object positions (resources or literals)</li>
<li><strong>Constraints:</strong> Type restrictions for each position</li>
</ul>

<p><strong>Example:</strong> \"This apple has a weight of 241.68 grams\" becomes a 'has-measurement' statement type with subject=apple, object1=weight (quality), object2=241.68 (value), object3=gram (unit).</p>

<p>This approach significantly lowers the barrier for domain experts to create FAIR knowledge graphs without requiring expertise in semantics, RDF, or ontology engineering.</p>""" ;
