Last Updated: 2026-10-31

## Overview

https://www.photoplanete.ch is a one-page showcase site for Photo Planète Charmilles, a photo shop, photo lab and copy service inside the Planète Charmilles shopping centre in Geneva, Switzerland. The same page exists in six languages. It is static HTML generated at build time by a dependency-free Node.js script and served by a small Express server. It was designed and developed by Kero Digital Solutions (Vernier, Genève, https://kero-digital.solutions).

## Public Areas

- The landing page in six languages: https://www.photoplanete.ch/, https://www.photoplanete.ch/en/, https://www.photoplanete.ch/es/, https://www.photoplanete.ch/pt/, https://www.photoplanete.ch/it/, https://www.photoplanete.ch/de/ — fully public
- Information page for AI systems: https://www.photoplanete.ch/llms.html — fully public
- AI discovery files at the site root and the OKF bundle under /okf/ — fully public
- There is no login area, no API, no form and no client portal. Every other path returns HTTP 404 (in the language of the path prefix).

## Structured Data (Schema.org / JSON-LD)

One graph per language page, with @ids on the domain so the nodes link together:
- Store + LocalBusiness   https://www.photoplanete.ch/#entreprise (address, geo, openingHoursSpecification, hasOfferCatalog with 19 offers, keywords, containedInPlace: the shopping centre)
- Organization            https://www.photoplanete.ch/#organisation (the shop as publisher)
- Organization            https://www.photoplanete.ch/#partenaire (Kero Digital Solutions, provider of the IT-support offer)
- WebSite                 https://www.photoplanete.ch/#site (inLanguage: the six codes)
- WebPage                 <language URL>#page
- FAQPage                 <language URL>#faq (every question of the page, in that language)
No Review, AggregateRating, Event or Product nodes exist and none should be inferred.

## Live Status

The open/closed indicator, the hours table and the countdown are computed in the browser in Europe/Zurich from the hours written into the HTML at build time (data-horaires). They are the same hours as in the JSON-LD openingHoursSpecification.
