It is important to know if an occurrence is natural, rather than an escapee from captivity, or say, a plant cultivated in a park, or indeed if the occurrence is extralimital to is normal range, e.g. a vagrant migratory bird that has drifted way off-course. Usually these records are excluded from spatial analyses. Pertinent information to this may be contained in Darwin Core fields: DwC:establishmentMeans (e.g. cultivated, invasive, escaped from captivity) and DwC:occurrenceStatus (e.g. present, absent). These fields could be used to record extralimital occurrences
