<noinclude>{{Pr4_UG_co_TOC}}<div id='pr4_ug'></noinclude>

Annotation properties (commonly referred to as "annotations")
allow arbitrary information to be added
to selected portions
of an [[{{#var:G}}OWL|OWL]] [[{{#var:G}}Ontology|ontology]].
Although some annotations are specific to a given ontology,
a number of annotations are in general use.

Like other [[{{#var:G}}Property|properties]],
annotations are name/value pairs.
The name is typically a
[{{#var:wp}}/Uniform_Resource_Identifier Uniform Resource Identifier]
([[{{#var:G}}URI|URI]])
such as <tt>owl:versionInfo</tt> or <tt>rdfs:label</tt>.
This allows the annotation's interpretation to be unambiguously specified.

<blockquote>
<p>
From the model theoretic point of view, these properties are comments.
All annotation properties are ignored by the reasoner,
and they may not themselves be structured by further axioms.
<tt>owl:AnnotationProperty</tt> assertions can have as objects
either individuals or data values, including <tt>rdf:XMLLiterals</tt>,
thus can embed arbitrary XML, including RDF/XML
(e.g., Annotea comments), XHTML, or SVG.
The built-in annotation properties
<tt>rdfs:label</tt> and <tt>rdfs:comment</tt>
are already extensively used in user interfaces (e.g., tool tips)
and in end-user renderings of ontologies.

The value of an annotation is always a text string,
but most values are more constrained than this, as:

* a data literal in a particular format (eg, date, float, integer)
* a prior version of the ontology
* a URI referring to a related resource (eg, another ontology)
