What is the difference between hyperlinks to other maps and contextual neighbourhoods?
A hyperlink is (just like in html) a link from an object in a map to another map. It has no controlled meaning other than a good place to go to from this concept or concept relation. A concept (or concept relation) can have different hyperlinks in different maps. The contextual neighbourhood of a concept (or concept relation) is the collection of contextmaps it occurs in. The neighbourhood is hencefort the same in all maps however when displaying a neighbourhood of a given concept in a certain context(map), this context is excluded from the collection.
