Content

This repo contains a Bokeh application that allows to validate D-SI unit parsing and conversion by the dsiUnit Module

The Web Gui Looks Like:

Install localy

git clone https://gitlab1.ptb.de/digitaldynamicmeasurement/dsi-parser-frontend.git
cd dsi-parser-frontend
pip install -r requirements.txt

Run the Bokeh Server

bokeh serve ./ --port 5020

Run the rest API

uvicorn restAPIServer:app --host 0.0.0.0 --port 5021

Use Docker Container

docker pull benesee/dsiunitsfrontend:latest
docker run -p 5020:5020 -p 5021:5021 benesee/dsiunitsfrontend:latest

Change target port by changing the first port number in the -p option to the desired port number urls of the services are:

• http://localhost:5020/dsi-parser-frontend/main for the Bokeh GUI
• http://localhost:5020 for the GUI
• http://localhost:5021/docs for the rest API documentation

API Documentation for Unit Conversion Service

This documentation covers the available REST API endpoints for converting unit strings to UTF-8 and LaTeX formats, as well as comparing different units for scalability and conversion. Each endpoint is described with its functionality, required input, and example responses.

Endpoints

Convert to UTF-8

• URL: /convert/utf8/
• Method: POST
• Description: Converts a unit string to its UTF-8 representation.
• Request Body:

  {
    "unit_string": "String"
  }

• Responses:
  • 200 OK:

    {
      "utf8_string": "Converted UTF-8 string"
    }

  • 500 Internal Server Error:

    {
      "detail": "Error message"
    }

Convert to LaTeX

• URL: /convert/latex/
• Method: POST
• Description: Converts a unit string to its LaTeX representation.
• Request Body:

  {
    "unit_string": "String"
  }

• Responses:
  • 200 OK:

    {
      "latex_string": "Converted LaTeX string"
    }

  • 500 Internal Server Error:

    {
      "detail": "Error message"
    }

Compare Units

• URL: /compare/units/
• Method: POST
• Description: Compares two unit strings for scalability and equivalence. Optionally performs a complete conversion comparison if specified.
• Request Body:

  {
    "unit_string1": "First unit string",
    "unit_string2": "Second unit string",
    "complete": false
  }

• Responses:
  • 200 OK:

    {
      "scale_factor": "Scale factor if units are scalable",
      "base_unit": "Base unit derived from comparison"
    }

  • 400 Bad Request:

    {
    "detail": "Warnings or error details from unit validation"
    }

  • 500 Internal Server Error:

    {
      "detail": "Error message"
    }

Error Handling

Errors are returned as standard HTTP response codes along with a JSON body specifying the detail of the error.

• 400 Bad Request: Sent when there's a validation error with the input data.
• 500 Internal Server Error: Sent when the server encounters an unexpected condition.

Example Usage

Here's an example using curl to make a request to the /convert/utf8/ endpoint:

curl -X POST "http://localhost:8000/convert/utf8/" -H "accept: application/json" -H "Content-Type: application/json" -d "{\"unit_string\":\"\\meter\"}"
