Digital Property Network

This Defines a business network where house sellers can list their properties for sale.

This business network defines:

Participant Person

Assets LandTitle SalesAgreement

Transaction RegisterPropertyForSale

A Person is responsible for a LandTitle. By creating a SalesAgreement between two Person participants you are then able to submit a RegisterPropertyForSale transaction.

To test this Business Network Definition in the Test tab:

Create two Person participants:

{
  "$class": "net.biz.digitalPropertyNetwork.Person",
  "personId": "personId:Billy",
  "firstName": "Billy",
  "lastName": "Thompson"
}

{
  "$class": "net.biz.digitalPropertyNetwork.Person",
  "personId": "personId:Jenny",
  "firstName": "Jenny",
  "lastName": "Jones"
}

Create a LandTitle asset:

{
  "$class": "net.biz.digitalPropertyNetwork.LandTitle",
  "titleId": "titleId:ABCD",
  "owner": "resource:net.biz.digitalPropertyNetwork.Person#personId:Billy",
  "information": "Detached House"
}

Create a SalesAgreement asset:

{
  "$class": "net.biz.digitalPropertyNetwork.SalesAgreement",
  "salesId": "salesId:1234",
  "buyer": "resource:net.biz.digitalPropertyNetwork.Person#personId:Jenny",
  "seller": "resource:net.biz.digitalPropertyNetwork.Person#personId:Billy",
  "title": "resource:net.biz.digitalPropertyNetwork.LandTitle#titleId:ABCD"
}

Submit a RegisterPropertyForSale transaction:

{
  "$class": "net.biz.digitalPropertyNetwork.RegisterPropertyForSale",
  "seller": "resource:net.biz.digitalPropertyNetwork.Person#personId:Billy",
  "title": "resource:net.biz.digitalPropertyNetwork.LandTitle#titleId:ABCD"
}

This RegisterPropertyForSale transaction will update titleId:ABCD LandTitle asset to forSale.

Congratulations!
