 <p>The Content Adapter pattern was suggested to be used to convert parsed documents to different Content Formats such as extracting the Plain Text of parsed HTML or PDF documents.</p>
 <p>The possibility to distinguish between the <em>Annotated Document</em> and the <em>Source Document</em> nicely supports this, because while Enhancement Engines can state that an Annotation is about the <em>Annotated Document</em> they can still state the exact <em>Source Document</em> that was used for processing. This allows e.g. to clearly state that the indexes of a text selection are based on the plain text version of the <em>Annotated Document</em>. </p>

 <h4 id="text_selectors">Text Selectors</h4>
-<p>The currently used FISE TextAnnotation differs form text selects of the Annotation-Ontology mainly in that, that it defines bot the actual annotation AND the selection within the text. Therefore when adopting the "Anootation -&gt; Seletor" model or the Annotation-Ontology all Annotation related properties of the FISE TextAnnotation must be separated from the properties describing the selection.</p>

Therefore when adopting the "Annotation -&gt; Selector" model or the Annotation-Ontology all Annotation related properties of the FISE TextAnnotation must be separated from the properties describing the selection.</p>
 <p>The Annotation-Ontology defines two text selectors: (1) the "OffsetRangeSelector" that uses char offset within the text to define a selection and (2) the "PrefixPostfixSelector" that uses a prefix, suffix and the selected text to define the selection based on the context. The Stanbol Enhancer currently uses both (context and offset) to define selection. However currently only single property "context" is used instead of the prefix, suffix model of the "PrefixPostfixSelector". In general the prefix, postfix based context definition as used by the Annotation-Ontology is better, because is allows to uniquely determine the selected part of the text even if the selected text appears multiple times within a given context. With the currently used model it is not possible to do that if the selected text appears several times in the provided context. </p>
-<p>The suggestion is to keep both (offset and context) based definition of text selection but switch to the prefix, suffix model for defining the context . Therefore stanbol:TextSelector will be defined as sub-class of both "OffsetRangeSelector" and "PrefixPostfixSelector".</p>

 <p>The proposal here is to use this specification for encoding selections within multi media files within the Annotation-Ontology. This will most likely require the definition of an MediaFragmentSelector as extension.</p>

 <h4 id="coreference_suggestion">Coreference Suggestion</h4>
 <p>This would allow to link several Text Annotations to suggest a co-reference between those two. This kind of AnnotationSet is expected to be used by NLP (Natural Language Processing) frameworks that can detect co-references. It might be also of interest for Engines that suggest Entities but keep an Annotation Context and therefore want to link persons only referred by the given or family name to an other occurrence that uses both.</p>
 <p>The type of the coreference could be captured by an special property of this annotation set type.</p>
