My 3rd Week of the GSoC’21

2 min readJul 2, 2021

From this blog, I will explain what I did in my third week of the GSoC’21. As you can remember from my previous blog, this week I have to make sure that all JSON message outputs of KBox have to follow the same structure as below.

{
"status_code": HTTP_CODE
"message": "information or error message"
"result": [expected resutls as a json array]
}

To achieve this I created a newer class called JSONSerilizer. So that I can handle the converting of all the outputs into json format in this class. Hence it will follow both the open-close principle and single responsibility principle.

After doing the necessary modifications, the final outcome looked like this

java -jar kbox.jar -list -o json{
    "status_code": 200,
    "message": "visited all KNs.",
    "results": [
        {
            "name": "http://purl.org/pcp-on-web/dbpedia",
            "format": "kibe",
            "version": "c9a618a875c5d46add88de4f00b538962f9359ad"
        },
        {
            "name": "http://purl.org/pcp-on-web/ontology",
            "format": "kibe",
            "version": "c9a618a875c5d46add88de4f00b538962f9359ad"
        },
        {
            "name": "http://purl.org/pcp-on-web/dataset",
            "format": "kibe",
            "version": "dd240892384222f91255b0a94fd772c5d540f38b"
        }
    ]
}java -jar kbox.jar -list -kns -o json{
    "status_code": 200,
    "message": "KNS table list",
    "results": ["https://github.com/AKSW/KBox/tree/master/kns/2.0"]
}java -jar kbox.jar -install -kns https://github.com/AKSW/KBox/tree/master/kns/2.0 -kns -o json{
    "status_code": 200,
    "message": "KNS installed.",
    "results": [true]
}java -jar kbox.jar -remove https://github.com/AKSW/KBox/tree/master/kns/2.0 -kns -o json{
    "status_code": 200,
    "message": "KNS removed.",
    "results": [true]
}java -jar kbox.jar -info http://purl.org/pcp-on-web/dbpedia -o json
{
    "status_code": 200,
    "message": "Information has been fetched.",
    "results": [{
        "License:": "[\"http://en.wikipedia.org/wiki/Wikipedia:Text_of_the_GNU_Free_Documentation_License\",\"http://en.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_Attribution-ShareAlike_3.0_Unported_License\"]",
        "version Tags:": ["latest"],
        "Format:": "kibe",
        "KN:": "http://purl.org/pcp-on-web/dbpedia",
        "label:": "PCP-on-Web ontology",
        "Owner:": "PCP-on-Web",
        "KNS:": "https://raw.githubusercontent.com/AKSW/kbox/master/kns/2.0",
        "Version:": "c9a618a875c5d46add88de4f00b538962f9359ad",
        "Publisher:": "KBox team"
    }]
}java -jar kbox.jar -search ontology -o json
{
    "status_code": 200,
    "message": "searching completed.",
    "results": [{
        "name": "http://purl.org/pcp-on-web/ontology",
        "format": "kibe",
        "version": "c9a618a875c5d46add88de4f00b538962f9359ad"
    }]
}java -jar kbox.jar -r-dir -o json
{
    "status_code": 200,
    "message": "Your current resource directory is: /home/sahandilshan/.kbox",
    "results": ["/home/sahandilshan/.kbox"]
}java -jar kbox.jar -version -o json
{
    "status_code": 200,
    "message": "KBox Version.",
    "results": ["v0.0.2-beta"]
}

This was the final output of the KBox. After this, I had the weekly meeting with my mentors and made the plans for the upcoming week.

Task for the upcoming weeks:

Fix the issue in kbox -remove command.
Integrate the modified KBox feature (Json Serialization) with the airML project.
Remove the hyphens from the KBox commands.
