FOLIO's location tree has four branches:
- Institutions (locinsts)
- Campuses (loccamps)
- Libraries (loclibs)
- Locations (loctions)
- Libraries (loclibs)
- Campuses (loccamps)
Each requires a dbId from the table above (a location requires an Id from all three of the other db tables.) Each location (whether or not it is associated with the same institutions, campuses, or libraries) must be unique. This means that in all of the libraries across our several campuses spanning our many institutions only one may have a location named "Reference" or "Reading Room". <rant> rather than requiring each location's name to be unique what should be required to be unique is the combination of location name and libraryId <lesserRant> the fact that locations also require a campusId and an institutionId is unnecessarily redundant</lesserRant></rant>
