| Identifier | http://rs.tdwg.org/dwc/terms/recordedBy |
| Class | http://rs.tdwg.org/dwc/terms/Occurrence |
| Definition | A list (concatenated and separated) of names of people, groups, or organizations responsible for recording the original Occurrence. The primary collector or observer, especially one who applies a personal identifier (recordNumber), should be listed first. |

The pointRadiusSpatialFit is undefined (and should be left blank) if the original representation is a point without uncertainty and the given georeference is not that same point (without uncertainty). If both the original and the given georeference are the same point, the pointRadiusSpatialFit is 1. |
