| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | abc9f747-53b3-0f38-e044-0003ba9b0d98 |
| Resource Identifier | This is the code assigned by the data owner. | BGS_CMD_REF210 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1983-08-31 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1983-09-18 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 5 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |
