Problem:

How to add a ToolTip to an entity?

Solution:

We make use of entity attribute called "TooltipPattern" to assign ToolTip to entities.

 "dataTooltipPattern" is used to build the entity object's tooltip. It can include static text as well as patterns-attributes in curly brackets.

Note: If "dataTooltipPattern" is not specified, then the label is used.

Example - 

{
 "uri": "configuration/entityTypes/GPO",
 "label": "GPO",
 "abstract": true,
 "skipValidationForAbstractType": true,
 "dataTooltipPattern": "configuration/entityTypes/GPO",
 "typeColor": "#AB8800",
 "typeIcon": "images/base_type/house.png",
 "typeImage": "images/defaultImage/no-loc.png",
 "typeGraphIcon": "images/graphIcon/location-icon.png",
 "extendsTypeURI": "configuration/entityTypes/Organization",
 "attributes": [...],
 "geoLocationAttributes": [...],
 "dataLabelPattern": "{Name}",
 "secondaryLabelPattern": "{businessCardAttributes}",
 "survivorshipGroups": [...],
 "imageAttributeURIs": [...],
 "analyticsAttributes": [...]
}

How to send data values to "dataTooltipPattern" - 

To send data to "dataTooltipPattern" you have to pass the value as "tooltip": "value"

For Example -

 "roles": [
 "configuration/roles/Client",
 "configuration/roles/Prospect"

 "sport",
 "movies"
