surrounding links

These are the links that connect the same identity group to at least two other identity groups in different EU information systems that are themselves also linked to one another creating a closed series of links in the form of a geometrical shape (e.g. triangle, rectangle). This means that the relation between those linked identity groups are connected to one another. If some of them are considered the same (and connected by white links), that means that it is impossible to also have a difference between them (connected by a green link). When a new link closes the series, inconsistencies might become apparent and will need to be resolved.
