2.3.7 context

Target namespace: http://schemas.microsoft.com/ink/2010/main

A CT_CtxNode element that specifies the context of a set of Ink traces stored in a traceGroup element as specified in [InkML].

This element MUST be a child of an emma:interpretation element ([EMMA] section 3.2). The emma:interpretation element must be a child of an inkml::annotationXML element ([InkML] section 6.3.2). The inkml:annotationXML element MUST be a child of an inkml:traceGroup element ([InkML] section 3.3.1).

The following W3C XML Schema ([XMLSCHEMA1] section 2.1) fragment specifies the contents of this element.

<xsd:element name="context" type="CT_CtxNode"/>

See section 5.7 for the full W3C XML Schema ([XMLSCHEMA1] section 2.1).

2.5.47 CT_CtxNode

Target namespace: http://schemas.microsoft.com/ink/2010/main

Referenced by: context

The CT_CtxNode defines an Ink context node and its properties. A context node is a logical collection of Ink traces. When Ink is drawn by the user, the Ink traces are analyzed and organized into a hierarchy of context nodes. Each context node has a type (specified by the type attribute) and can have zero or more child content nodes. For example, a writingRegion content node can have one or more paragraph content nodes. In addition, context nodes can have relational links to each other. For example, if a word is underlined, the context node representing the ink word and the context node representing the underline are linked.

For example, the following figure shows ink that is analyzed as shown in the following code example.

Figure 29: Example ink text

<context type="writingRegion"/>

...

<context type="paragraph"/>

...

<context type="line"/>

...

<context type="inkWord"/>

...

<context type="inkWord">

<destinationLink direction="with" ref="id of inkDrawing below"/>

</context>

<context type="inkDrawing" semanticType="underline">

<sourceLink direction="with" ref="id of inkWord above"/>
