> We should replace this with a new replace the script with a new IncrementInterestAction that would do the following:
> - (optional) check if topic exists to allow enforcement of only accepting existing topics
> - increment the interest
> Interests inside profiles:
> {code}
> properties : {
>   interests : {
>     topic1 : 30.0,
>     topic2: 20.0
>   }
> } 
> {code}
> Global configuration setting in https://github.com/apache/unomi/blob/master/package/src/main/resources/etc/custom.system.properties to setup min/max and relative value
> {code}
> org.apache.unomi.interests.min_value = ${env:UNOMI_INTERESTS_MIN_VALUE:-0.0}
> org.apache.unomi.interests.max_value = ${env:UNOMI_INTERESTS_MAX_VALUE:-150.0}
> org.apache.unomi.interests.divider_value = ${env:UNOMI_INTERESTS_DIVIDER_VALUE:-100.0}
> {code}
> and then in OSGI blueprint files, retrieve the values as such:
> So to calculate a cdp_interests we would to :
> {code}
> CDP_Profile.cdp_interests.topic1.score = min(properties.interests.topic1, divider_interest_value) / divider_interest_value
> {code}
> Incrementing / decrementing interest values should be capped by min_value and max_value
> {code}
> r = profile.properties['interests']; 
> foreach(interest : event.target.properties['interests'].entrySet()) { 
>   if (r == null) { 
>     r = [interest.key: interest.value] 
>   } else if (r[interest.key] != null) { 
>     r[interest.key] = r[interest.key] + interest.value 
>   } else { 
>     r[interest.key] = interest.value 
>   }
>   r[interest.key] = max(min(r[interest.key], max_interest_value), min_interest_value)
> }
> {code}
> Example of eventInterestProperty :
> "eventInterestProperty" : "eventProperty::target.properties.interests"
