GSoC 2020 Data transaction implementation on pygeoapi

Introduction

Idea

pygeoapi is a python server implementation of the OGC API suite of standards. The project emerged as part of the next generation OGC API efforts in 2018 and provides the capability for organizations to deploy a RESTful OGC API endpoint using OpenAPI, GeoJSON, and HTML. pygeoapi is open source and released under an MIT license.

This GSoC project aims to add support for simple transactions in pygeoapi. This project will implement Create, Update, Delete operations in pygeoapi data providers, thereby enabling all standard CRUD transactions in pygeoapi. This will enable an application developer to perform a transaction in a pygeoapi data provider through an HTTP request containing the resource id and suitable HTTP verb (POST/PUT/DELETE/PATCH). The project proposal is based on OGC API - Features - Part 4: Simple Transactions.

Project proposal

My proposal for GSoC 2020 can be found at Proposal.

Advantages from this project

pygeoapi implements OGC WFS 3.0 (OGC Feature API) which is fully RESTful. This makes it much easier for the application developers to work with. This project idea implements 'Part 4 : Simple Transactions' of this OGC standard. It adds transactional capabilities to the pygeoapi data providers by which application developers can perform transactions via the RESTful API itself. A RESTful API supporting complete CRUD transactions will be preferred by most application developers over other non-RESTful APIs. So this will make pygeoapi a more popular choice among application developers.
