Conversion of CSV file from a P&ID diagram to DTDL file to make a digital twin

Question

I have a csv file which is the output of a p&id diagram. Is there any document or method/links which i can use for converting the csv file to a dtdl file and create a twin accordingly using that?

As per my understanding of the query, you need to create a digital twins graph out of CSV files extracted from P&ID diagram. Correct me if I'm wrong.

One way to get this data into Azure Digital Twins is to write a code to interpret the CSV file into commands to create twins and relationships. The following code sample illustrates reading the data from the CSV file and creating a twin graph in Azure Digital Twins.

Example:

// Method to ingest data from the CSV file  
        public static List<List<string>> ReadData()  
        {  
            string path = "<path-to>/filename.csv";  
            string[] lines = System.IO.File.ReadAllLines(path);  
            List<List<string>> data = new List<List<string>>();  
            int count = 0;  
            foreach (string line in lines)  
            {  
                if (count++ == 0)  
                    continue;  
                List<string> cols = new List<string>();  
                data.Add(cols);  
                string[] columns = line.Split(',');  
                foreach (string column in columns)  
                {  
                    cols.Add(column);  
                }  
            }  
            return data;  
        }  

// Method to create the digital twins client  
        private static DigitalTwinsClient createDTClient()  
        {  
  
            string adtInstanceUrl = "https://<your-instance-hostname>";  
            var credentials = new DefaultAzureCredential();  
            DigitalTwinsClient client = new DigitalTwinsClient(new Uri(adtInstanceUrl), credentials);  
            return client;  
        }  

I would suggest you, go through the Create graph from a CSV file documentation sample and see if it helps.

Do let us know if you have any further queries.
