This list is not an accurate science, more a mnemonic.  This means that there may be errors. As I only speak german and about 80% english, the list focusses on the corresponding countries.

Version
It's a kind of ver 0.1. I'm not sure yet that stackby is the ideal tool. But it allows 1,500 entries in the free version. I still find the filters too complicated. Stay tuned.

.Durability
In my experience, brand communication and especially brand documentation doesn't last forever. Things change. Therefore, it can of course happen that links no longer work.

Brand
Name of the company, country, city, university, organisation ...

Name
Name of the portal or design system. Mostly taken from the page title.

Sender
Rough categorisation according to 

• com = company
• gov = public administration
• edu = universities, schools, colleges
• org = organisation

Accessibility: 

• closed = No access to brand content possible.
• open = access to brand content is possible. Please note that often only partial access is possible, as certain content is not publicly available for a variety of reasons (legal, communication strategy, licences). Examples: fonts, assets, office templates

Language
The obvious language, there always tends to be more than that.

System
A rough analysis via Wappalyzer and Whatcms.org. It's about getting a feeling of which systems are used. PDF means that there is a page with perhaps a little information that quickly links to a PDF. We do not (yet) link directly to PDFs.
