Introduction

Hi everyone! As GSoC 2021 is coming to a close, I am writing this diary entry as a final report on the progress of my GSoC project, the OpeningHoursEvaluator, in the second period of GSoC.

Project Summary

An evaluator for opening hours tag according to OSM opening hours specification.

Second Period’s Summary

Just to recap, the evaluator from the first period supports almost all the syntaxes defined by the specifications, ranging from something as small as time and a wider range such as year. Building from my previous progress, I have added geocoding to the evaluator, for use in calculation of variable time such as dawn, dusk, sunrise, sunset. I have also added support for holiday data for the corresponding opening hours tag PH and SH, which currently supports 168 countries. Combined with my progress in the first period, the current evaluator now supports evaluation of all the syntax defined by the grammar, and is ready for use in production.

Introduction

Hi everyone! As the first evaluation period is closing in, I am writing this diary entry as an update on the progress of my GSoC project for OSM, the OpeningHoursEvaluator.

Using the test-driven development approach (which, by the way, works wonderfully with this project), suggested by one of my mentors, Simon Poole, my project OpeningHoursEvaluator, an evaluator for the opening hours tag defined by OSM, is progressing fairly well, with the evaluator supporting almost all the syntaxes defined by the specifications, ranging from something as small as time and a wider range such as year, except for certain syntax where the OpeningHoursParser have yet to cover, variable time (dawn, sunrise, sunset, dusk), and also country-specific public holidays and school holidays (PH, SH). This is something I intend to complete in the second period of GSoC.

Introduction

Hi OSM community! My name is Vuong Ho, an international student at the University of Rochester in the U.S. I am currently living in Ho Chi Minh City, Vietnam, though, since due to Covid-19, I haven’t had the chance to go the States yet. In my free time, I like to tinker away with my small personal projects, play games with my friend, and watch cat videos on Youtube. Once this pandemic is over, I am thinking of going mapping around too!

Though I have never contributed to open-source, I really like the idea of openly sharing software for public use and would like to contribute to a project someday. Therefore, I am really glad to have the opportunity in this GSoC to contribute to OpenStreetMap!

My GSoC project: Opening hours tag evaluator

As noted by Simon Poole, the current opening hours parser lacks a complete evaluator for its input opening hours tag. This project will center around building an evaluator to determine if an input of date and time translates to a location is currently opened or closed based on an opening hours tag (specifications here). This evaluator will also support checking sunrise/sunset and holiday information, if any is provided in the opening hours tag, since these are supported by the parser.

The evaluator will be in the form of a data structure resembling a compact calendar, though this may change over the course of the project since I will be making use of the test-driven development framework to develop the evaluator. The information on sunrise/sunset and holidays is taken externally, using other open-source libraries and data. My full project proposal can be found here.

The milestones for my project in the span of two months of this year’s GSoC are:

1. Creating a simple evaluator that supports checking open/close status of time and day
2. Adding support for sunrise/sunset information
3. Adding support for holidays information
