The basic idea is to provide stable urls that show a Wikidata item's sitelinks in a single language. Possibly also showing related items, e.g. items found from "What links here" and/or items with nearby coordinates. If combined with a tool to generate QR codes for the stable urls, this would be a solution to https://meta.wikimedia.org/wiki/2017_Community_Wishlist_Survey/Wikidata/Qr_codes_for_all_items

This tool is located on the Wikimedia Toolforge, at https://tools.wmflabs.org/portal/. To update:

1. Login with to toolforge with ssh:

   $ ssh -i ~/.ssh/id_rsa user@login.tools.wmflabs.org

2. Become the tool account:

   $ become portal

3. Pull from GitHub repo into the public_html folder:

   $ cd public_html

   $ git pull

4. If the .lighttpd.conf file has changed, that file needs to be copied to the root directory:

   $ cp public_html/.lighttpd.conf .lighttpd.conf

5. Restart the webservice:

   $ webservice stop

   $ webservice start

The stable url format is {base-url}/portal/{item}/{lang-code} (e.g. {base-url}/portal/Q12345/en) with /{lang-code} being optional.
This maps to {base-url}/portal/index.php?id={item}&lang={lang-code} (via the url rewrite rules in .lighttpd.conf file).

Item titles, descriptions, and sitelinks are retrieved from the Wikidata api.

I18n: labels and descriptions from Wikidata are already in the correct langauge. Other strings are pulled from json files. If the language is not specified, the device language is detected.
