HotSpotting summarizes a general technique in UBIK®, that allows to overlay data on the visual representation of other UBIK® objects. The overlaid data can be of quite a variety, starting from Annotations (also known as Redlining or Inking) over Links/Cross-references between objects, to UBIK® Properties in all their different possible types and appearances. While HotSpotting is an abstract approach that could be applied to any kind of UBIK® object, the client currently only supports displaying and interacting with HotSpots on Document objects.

Overview
HotSpotting consists of 3 main elements, the Target, the Layer(s) and the HotSpots:
Target
A HotSpotting target can be basically any UBIK® object that holds the classification HotSpotting target. In most of the use cases, this target will be file document or a derivative of that class.
Layer
A layer can be envisioned as a transparent film that is overlaid on the target and contains the actual HotSpots. Technically their can be as many layers as desired, overlaying each others. A layer covers the whole physical area of its target, i.e. the dimensions of the page of a document.
HotSpot
A HotSpot is a single data object that sits on a layer and typically has a visual representation, such as the value of a property it represents. There are different types of HotSpots:
InputSpot
An InputSpot is a link to a property from a UBIK® Object. It displays the value of the property and reacts to user interaction, e.g. with popping up the property editor when tapped on it. Any existing UBIK® property can be represented as an InputSpot.
MediaSpot
A MediaSpot is a specialization of an InputSpot that works with properties that can hold media (Audio/Video) data.
SignatureSpot
A SignatureSpot is a specialization of an InputSpot that works with properties of type Signature. It allows for graphically signing of objects.
Annotation
An Annotation is a collection of Ink strokes that sits on a layer and typically represents redlining or additional information to a document, like a diagram or a photo.
