Technical Note: Database Architecture
This plugin integrates <code>webcalendar-core</code>, a framework-agnostic Composer library that provides all calendar business logic (events, recurrence, iCal, permissions) through 17 repository classes. These repositories require PDO and use exclusively parameterized prepared statements — no raw SQL concatenation. WordPress-specific data (users, options, capabilities) is accessed via <code>$wpdb</code> through the plugin’s Bridge layer (<code>WpUserRepository</code>, <code>WpConfigRepository</code>, etc.). See <code>src/Bridge/PdoFactory.php</code> for the connection factory.
<h3>External Services</h3>
This plugin connects to the following third-party services:
<h4>Nager.Date API</h4>

* <a href="https://date.nager.at/Privacy" rel="nofollow ugc">Privacy Policy</a>
<h4>Google Calendar Public Feeds</h4>
Alternative holiday source. Fetches public .ics files from Google. 
* Endpoint: https://calendar.google.com/calendar/ical/ 
* <a href="https://policies.google.com/privacy" rel="nofollow ugc">Google Privacy Policy</a> 
* <a href="https://policies.google.com/terms" rel="nofollow ugc">Google Terms of Service</a>

<h4>Remote Calendar Sync (User-Configured)</h4>
When remote iCal subscriptions are configured, the plugin fetches .ics data from 
those URLs via HTTP GET. No user data is transmitted to these services.
<h4>OpenStreetMap / Nominatim</h4>
When a single event page has a location and the map provider is set to OpenStreetMap 
(the default), the plugin geocodes the address via the Nominatim API and displays a 
map using OpenStreetMap tile servers. The event location string is sent as a search 
query. No user personal data is transmitted. 
* Geocoding endpoint: https://nominatim.openstreetmap.org/search 
* Tile server: https://tile.openstreetmap.org/

* <a href="https://wiki.osmfoundation.org/wiki/Privacy_Policy" rel="nofollow ugc">OpenStreetMap Privacy Policy</a>
<h4>Google Maps Embed API</h4>
When the map provider is set to Google Maps in settings, single event pages display 
an embedded Google Map for the event location. The event location string and your 
Google Maps API key are sent to Google. No other user data is transmitted. 
* Endpoint: https://www.google.com/maps/embed/v1/place 
* <a href="https://cloud.google.com/maps-platform/terms" rel="nofollow ugc">Google Maps Platform Terms of Service</a> 
* <a href="https://policies.google.com/privacy" rel="nofollow ugc">Google Privacy Policy</a>
<h4>Add to Calendar Links</h4>
Single event pages include “Add to Calendar” buttons that generate links to Google 
Calendar, Outlook.com, and Yahoo Calendar. When a visitor clicks a button, the event 
title, date, time, location, and description are passed as URL parameters to the 
chosen service. No data is sent until the visitor clicks. 
* Google Calendar: https://www.google.com/calendar/render — <a href="https://policies.google.com/terms" rel="nofollow ugc">Terms</a> | <a href="https://policies.google.com/privacy" rel="nofollow ugc">Privacy</a>

<h3>Development & Source Code</h3>
Full unminified source for this plugin is included in this distribution under GPL-2.0-or-later — you do not need to download anything external to rebuild the compiled assets.
What ships in this zip:
<ul>
<li><code>src/</code> — unminified React/JSX source for all admin components, frontend calendar, and the mini-calendar widget</li>
<li><code>build/</code> — the pre-compiled minified bundles (what the plugin actually loads at runtime)</li>
<li><code>package.json</code> + <code>package-lock.json</code> — Node build manifest and lockfile for reproducible <code>npm install</code></li>
<li><code>composer.json</code> — PHP dependency manifest</li>
</ul>
Rebuilding the compiled assets from source:
Prerequisites: PHP 8.2 or higher with Composer 2, Node.js 20 or higher with npm 10.
<ol>
<li><code>composer install</code> — install PHP dependencies</li>
<li><code>npm install</code> — install JavaScript build dependencies (@wordpress/scripts, React, Toast UI Calendar, Leaflet, Tiptap)</li>
<li><code>npm run build</code> — compile <code>src/index.js</code> and <code>src/frontend.js</code> into the minified bundles under <code>build/</code></li>
</ol>
The compiled output in <code>build/</code> is byte-reproducible from the matching <code>src/</code> at the same version using this toolchain.

Jomres is a commission-free, responsive, Open Source multi-vendor, multi-language, multi-property online booking plugin for accommodation, rentals and tours used by thousands of businesses worldwide to manage their properties and reservations. You can create an unlimited number of booking websites, accessible to customers on any device, in any language.
From basic features like secure frontend property administration, comprehensive and flexible <a href="http://www.jomres.net/manual/site-managers-guide-2/402-search-widgets" rel="nofollow ugc">search features</a>, <a href="http://www.jomres.net/manual/property-managers-guide-2/41-your-toolbar/bookings/328-jomres-ical" rel="nofollow ugc">iCal import and export</a>, through to powerful developer tools such as its built-in <a href="http://www.jomres.net/manual/developers-guide-2/90-channel-management-framework" rel="nofollow ugc">REST API</a> and <a href="http://www.jomres.net/manual/developers-guide-2/64-webhooks" rel="nofollow ugc">Webhooks</a> functionality, there’s something here for everybody. Whether you are looking for a booking engine for a single property site, or a complete portal, Jomres is where it’s at.
Jomres is created and maintained by me, Vince Wooll. I am not a designer or a marketer, I’m a software engineer who believes that there’s still a place for the solo developer in today’s internet. I think of Jomres as less a booking engine and more a toolkit, with a set of tools that my users can use to build their own unique online websites. Jomres follows that line of thinking with it’s strong emphasis on giving you, the user, the <a href="http://www.jomres.net/documentation/" rel="nofollow ugc">information and tools</a> you need to create something amazing.
<h3>What’s new?</h3>
<h4>Bootstrap no longer required</h4>
Jomres can now be run on non-Bootstrap themes. This means that you can use Jomres on any theme, not just Bootstrap themes. If you’re using a Bootstrap theme, you can still use the Bootstrap version of Jomres, but you don’t have to.
<h3>Demos</h3>
<a href="http://wordpress-portal.jomres.net/" rel="nofollow ugc">See the Portal Demo here – a variety of bookable items, multiple owners</a>
License holders can download the “QuickStart” zip file that enables you to deploy a full installation of WordPress with everything already set up to exactly match the Demo. You can be up-and-running, with a fully-featured booking website that looks terrific, within minutes.
