Location
To answer the yes/no question "Is the selected page located in P?", an attribute is used with value "v" for "yes", and undefined for "no". Additional possibilities are "partly", "from 2007", etc. It can also be used in selection, possibly combined with a condition regarding the nature of the page, e.g. Attribute:City.
Example:
To answer the open question "Where is the selected page located?", Relation:Located in is used. Usually only the next level is annotated. It can also be used in selection ("all pages in P"), possibly combined with a condition regarding the nature of the page, e.g. Attribute:City.
To answer the more specific open question "In which Q is the selected page P located?" (where Q denotes a level or type of subdivision), a relation "has location Q" is used. For selection "has location Q::S ("all pages in Q S") is (if S is of type Q) equivalent with "located in::S". It can be combined with a condition regarding the nature of the page, e.g. Attribute:City.
