MetadataExtended

A CityJSON Extension to store ISO19115-compliant metadata, extends the few metadata properties of the core. Works with CityJSON v1.1 and v2.0.

The CityJSON core "metadata" has those 6 properties (see specifications for more details:

  • geographicalExtent
  • identifier
  • pointOfContact
  • referenceDate
  • referenceSystem
  • title

and the MetadataExtended Extension adds several ISO19115-compliant properties, those are documented in the paper A metadata ADE for CityGML.

Integrated in cjio

The easiest way to use the MetadataExtended is by using the software cjio. Those 4 operators are related:

bash metadata_create Add the +metadata-extended properties. metadata_get Shows the metadata and +metadata-extended of this dataset. metadata_remove Remove the +metadata-extended properties. metadata_update Update the +metadata-extended.

and most operators (eg subset, lod_filter, etc.) will update the "+metadata-extended" property.

If the "+metadata-extended" is not present in the file, then nothing will be done. But if it is present then it'll be automatically updated.

To start use the "+metadata-extended":

bash cjio myfile.city.json metadata_create save myfile.city.json

To remove the "+metadata-extended" property (but keep "metadata"):

bash cjio myfile.city.json metadata_remove save myfile.city.json

Example of a CityJSON file using the +metadata-extended
