| Notes: | ||
| 1. | There may be many instances of the date property with different date types including publication, revision or creation. The order of these instances is not fixed. | |
| 2. | There may be many instances of the identifier property corresponding to RSSHNA, RSID or identifiers out of DMF scope. The one corresponding to RSSHNA is the first one for which the codeSpace value matches RSSERI. | |
| 3. | There may be many instances of the descriptiveKeywords property providing keywords from different thesauri. The order of these instances is not fixed. | |
| 4. | There may be many instances of the resourceConstraints property. The order of these instances is not fixed. | |
| 5. | Except for non-geographic data and loose services, one of boundingBox or geogId is mandatory. | |
| 6. | There may be many instances of the spatialResolution property providing either equivalent scales or ground sample distances. The order of these instances is not fixed. | |
| 7. | The language property can be defaulted to the value of the Metadata Language when the resource does not contain textual information. | |
| 8. | Units of measures are implemented in the ISO metadata by reference to a unit of measure register. The URL of the reference can be derived from the codelist value of the DMF Property. See Additional Instructions | |
| 9. | Default value for this element should be set by the implementer’s security policy. | |
| 10. | Default values are role=user and organisationName=undefined | |
| 11. | Preceded by "Level of detail: " | |
| 12. | Preceded by "Vertical resolution: ". Value and unit are concatenated. Eg: 'Vertical resolution: 2 m'. | |
| 13. | Preceded by "Temporal resolution: ". Eg: 'Temporal resolution: 5 10-3s' | |
| 14. | If TopicCategory is "disaster" it should be mapped to a keyword. | |
