This tool imports a JSON payload (aka. Document) and creates a CTO file, which is the Fabric Composer modeling language. The CTO file comprised of cto artifacts ("concept" only at this stage) from JSON objects and arrays.
| JSON | CTO | Note |
|---|---|---|
| BigInteger | Long | |
| Long | Long | |
| Double | Double | |
| Int | Integer | |
| Decimal | String | No Decimal type in CTO, This may not be desired |
| Binary | String | No Binary type in CTO, needs to be processed in the script |
| Boolean | Boolean | |
| Null | String | This may not be desired |
| Text | String | |
| others | Jackson parser Node Type |
You need Maven with Java 8
- Clone repository in a folder, called xyz later on
- cd xyz/json-to-cto
- mvn install
- After successful test you will see 5 JSON and corresponding CTO files under xyz/json-to-cto/target/test-classes/Json/Payload .
- TwitterGetUser.josn is different from others because it starts as a JSON array and not a JSON object
To test your own data:
- Drop a JSON file at xyz/json-to-cto/scr/test/resources/Json/Payload
- cd xyz/json-to-cto
- mvn test
If the JSON file is valid and does not break the tool will generate a file with extension .cto at: xyz/json-to-cto/target/test-classes/Json/Payload
There is a log42j.properties file in the xyz/json-to-cto/scr/test/resources, which the debugging level is set to INFO (not verbose) by default. It can be changed to DEBUG (less verbose) and TRACE (very verbose). Output will be directed to System out(console)
