Prior Knowledge of Java/J2EE.
Prior Knowledge of Spring Boot.
Prior Knowledge of REST APIs and related concepts like path parameters, headers, JSON etc.
Prior knowledge of Git.
Prior knowledge of eGov-mdms service, eGov-persister, eGov-user, eGov-location, eGov-localization, eGov-idgen.
FUNCTIONALITY:
The Property service provides multiple functionality starting from serving as a central repository where property information are registered for reference of citizen and other municipality provided services such as water connection and sewerage management. An assessment can be done so as to calculate and pay tax on the property. The different services provided by the property services are
Property Registry
Assessment
Mutation
Bifurcation
consolidation
SETUP AND USAGE:
The Application is present among the core group of applications available in the eGov-services git repository. The spring boot application needs lombok* extension added in your IDE to load it. Once the application is up and running API requests can be posted to the url and ids can be generated.
*in case of intellij the plugin can be installed directly, for eclipse the lombok jar location has to be added in eclipse.ini file in this format javaagent:lombok.jar
For the API information please refer the swagger yaml, GOTO : https://editor.swagger.io/ and click on file -> import url Then add the raw url of the API doc in the pop up.
https://github.com/egovernments/municipal-services/blob/master/docs/property-services/Assessment.yml
Incase the url is unavailable, please go to the docs folder of municipal-services git repo

Property Search Parameters config (filter for search based on fields by user Type)

employee.allowed.search.params = accountId,ids,propertyDetailids,mobileNumber,oldpropertyids
Explanation for Registry:
The registry flow flow helps the citizen/Employee to create a property in the system with the minimal information required. Other workflows such as assessment or mutation can be triggered on the existing registry. The registry entry can be created, updated and cancelled, searched. The same entry in registry can be referred by other modules for their business purposes.
Assessment APIs:
Assessment is a snapshot of Property for a given transaction on that Property. These APIs provide functionalities to create/update/search the assessments. An assessment cannot exist without a property.
Postman Collection:
https://www.getpostman.com/collections/d1a02a29203d110df289
Configs:
Assessment shares most of the configs with Property as mentioned above, only exclusive properties are mentioned in this section.
IDGEN:
assessment id key = pt.assessmentnumber
assessment id format = PB-AS-[cy:yyyy-MM-dd]-[SEQ_EG_PT_ASSM]
KAFKA TOPICS:
save-pt-assessment
update-pt-assessment
Services required to be running:
egov-mdms-service
egov-idgen
egov-persister
egov-workflow-v2
Workflow integration can be controlled by the following two properties:
assessment.workflow.enabled=true assessment.workflow.trigger.param=usageCategory,occupancyType,occupancyDate
The first property switches workflow on or off, while the second property provides a way to control which field change can trigger workflow. A businessService needs to be created using the workflow
/egov-workflow-v2/egov-wf/businessservice/_create API .

Mutation calculator:
Calculation Logic
The calculation logic for mutation fee depends on the usage type of property (RESIDENTIAL , NON RESIDENTIAL etc ) and current market value of the property.
Usage type | Minimum Market value | Maximum Market Value | Rate Percentage | Fixed amount | Calculation Type |
Residential | 0 | X lacs | A% of CMV | INR G | FLAT |
Non -Residential | 0 | X lacs | E% of CMV | INR Q | RATE |
Residential | X+1 Lacs | Y Lacs | B% of CMV | INR H | FLAT |
Non -Residential | X+1 Lacs | Y Lacs | B% of CMV | INR H | RATE |
Residential | Y+1 Lacs | >Y+1Lacs | D% of CMV | INR L | FLAT |
Non -Residential | Y+1 Lacs | >Y+1Lacs | C% of CMV | INR I | RATE |
If the current market value (CMV) of the property comes in between minimum and maximum market value range of billing slab and the usage type of property match with the usage type for that billing slab then the mutation fees for that property is the amount mentioned in that particular billing slab.
Further there are two calculation types which are FLAT and RATE which has to set by state/ulb for their billing slab for property mutation. If the calculation type is set as FLAT then mutation fee is the fixed amount mentioned in billing slab which is used for the property.
If the calculation type is set as RATE the Mutation fee is X% of current market value, where X is percentage rate mentioned in billing slab which is used for the property.
Other factors influencing calculation can be :
Ownership type
Property type
Locality
Rebate and Penalty
When the property is registered for mutation/transfer of ownership and all the document is submitted, then the mutation fees has to pay within specified period of time of property mutation registration date. If a person fails to pay the fees amount before the deadline date, then some penalty charges has to pay. Penalty charge is Y% of tax amount. The penalty percentage is set by the state/ulb. If a person pays the fees amount within the specified month of property mutation registration date, then a certain amount is rebated from tax amount. Rebate charge is Z% of tax amount. The rebate percentage is set by state/ulb.
Note: For mutation fees calculation, document date value (means the date at which property is registered for mutation), market value of property, usage type value of property is essential.
