Develop binding from sitemaps and items

this is my items file-

String A_Temperature “A_Temperature:[%s °C]” {}
String A_Pressure “A_Pressure:[%s mb]” {}
String A_Humidity “A_Humidity:[%s %%]” {}
DateTime Today “Last Updated Time [%1$tH:%1$tM:%1$tS]”{}
String MyString “Value:[%s]” {mqtt="<[mosquitto:ge:state:default]"}

this is my sitemap file-
sitemap test

Frame label="ST Board"
	Text item=A_Pressure
	Text item=A_Temperature
	Text item=Today


and this is my rules file
import org.openhab.core.library.types.*
import org.openhab.core.persistence.*
import org.openhab.model.script.actions.*
import org.openhab.core.library.types.DateTimeType
import java.text.util.Calendar
import java.text.SimpleDateFormat
rule “MqttPostionPatrikParse”
Item MyString received update
var String json=(MyString.state as StringType).toString
var String temp=transform(“JSONPATH”,"$.d.A_Temperature",json)
var String press=transform(“JSONPATH”,"$.d.A_Pressure",json)
var String humi=transform(“JSONPATH”,"$.d.A_Humidity",json)
Today.sendCommand(new DateTimeType())

And these are working fine in Basic UI.
My question is can I make a binding for openhab2 with the help of these files.

What do you want to achieve?

A binding is a way to “connect your smart home’s devices and technologies to openHAB” (Source)

I just want that my all these files will link to my binding.

hmmm… I recommend that you spend some time on to better understand openHAB.

What do you mean by “my binding”?
Which binding are you using?

I need to develop a new binding from all these files.

@Geetika_Varshney - could you please tell us what you understand under the word “binding”?

A binding is a connector for a specific purpose. You seem to want to create an OpenHAB setup for your home!?
