This repository contains Java Springboot backend used to generate semantic annotations from JSON payloads uploaded from the webapp application. The semantic annotations are saved on the blockchain network as transactions.
Currently, the application is served using tomcat. WAR can be built by running mvn package at project's root. Then, copy / symlink the obtained .war package to your tomcat home folder. At the moment, it's symlinked, so should any changes happen, simple mvn package should be sufficient.
Two enpoits are provided
/transaction/save
POST endpoint expecting a JSON payload, which then is sent to blockchain instance, set as const to localhost:3000/api/delivery.
The JSON is prior enriched by semantic annotations.
For debugging purposes, simple POST endpoint that saves any payload to log folder.
You will need to provide APP_MASTER_USERNAME and APP_MASTER_PASSWORD to the server, which is used to access the blockchain endpoints. As this is currently run via tomcat, the variables are set in tomcat.
The code also contains a package com.proofd.evaluate. The SPARQL queries can be found in server/src/main/java/com/proofd/evaluate/EvalQueries.java. You can re-run the competency questions evaluation by running the main method in RunEval.java. The code will use files in the resource folder which contain local copies of the required ontologies, university catering delivery plan, and a sample execution trace for a non-compliant use case (i.e. this produces the richest provenance records) which was produced by the server app
