A context-map is made up of layouts, which might be of the following kinds:

• NodeLayout - a grouping of layouts.
• ConceptLayout - presents a resource as a concept.
• StatementLayout - presents a statement, i.e. a reification of a triple.
• LiteralStatementLayout - presents a statement with a literal as object.

A NodeLayout has the following properties:

• rdf:type pointing to the lns:NodeLayout class.
• lns:inContextMap tells which context-map the nodelayout is expressed in.
• lns:priority is a real number, used to order layers.
• dc:title for a language controlled name.
• dc:description for a language controlled description.

A ConceptLayout has the following properties:

• rdf:type pointing to the lns:ConceptLayout class.
• lns:inContextMap tells which context-map the concept is presented in.
• lns:inNodeLayout points which NodeLayout the concept is shown in.
• lns:priority is a real number, used to order layouts in nodeLayouts.
• lns:location is the position of the concept in the map.
• lns:dimension is the width and height of the concepts boundingbox.
• lns:horizontalTextAnchor
• lns:verticalTextAnchor
• lns:displayResource
• navns:hyperlink

A StatementLayout has all of the properties from ConceptLayout except the type, and:

• rdf:type pointing to the lns:StatementLayout
• lns:subjectLayout pointing to a layout whoose concept is in the subject position in the triple.
• lns:objectLayout pointing to a layout whoose concept is in the object position in the triple.
• lns:statementLine pointing to a sequence of points.
• lns:statementLinePathType pointing to either a lns:LinePathType_Straight or lns:LinePathType_Curve corresponding to either a simple chain of points or Bezier curves with four points per segment (two consequtive points share one point so the amount of points are n*3+1 where n is the number of segments of the line).
• lns:boxLine pointing to a sequence of points, but the line is intended to connect the statementLine with the box, if made visible.
• lns:boxLinePathType similar as for lns:statementLinePathType.

A LiteralStatementLayout has all of the properties from StatmentLayout above except objectLayout and the type, and:

• rdf:type pointing to the lns:LiteralStatementLayout
• lns:literalLocation pointing to a position for the literal in the context-map.
• lns:literalDimension is the width and height of the literal boundingbox.

LoadContainer is detected from where the type information is expressed.
RelevantContainers for a:

• conceptLayout is the loadContainer
• nodeLayout are the loadContainer of the NodeLayout AND all relevantContainers of its child layouts.
• contextMap are the the same as for nodeLayouts.
