tbd: currently, this is just a placeholder page.
Categories are pre-defined tags.
Maybe we can use hierarchical tags, e.g. Region.US, Region.Europe, Country.CH, Country, NL, Provider.Google, Provider.Microsoft etc.
Then we could convert the category links below to menus with a checklist. A user can check the categories he wants (e.g. Google Services in Europe) and select the service offering accordingly. This means that the Category links in the footer below would then lead to a preselected list of services in the catalog.
Additionally, we could offer custom tags, ie. user is able to create his own tags.
