CatalogMetadata Class
Represents a metadata document from Carmenta Engine catalog, with information about a catalog map or dataset.
NuGet/Assembly: Carmenta.Engine.5.16.2.nupkg (in the CECatalog assembly)
Syntax
public class CatalogMetadata : EngineObjectRemarks
The class holds metadata information about a map or dataset in a Carmenta Engine catalog. An instance of this class can be used to load the corresponding map or dataset from the catalog, using the Catalog.LoadMap or Catalog.LoadDataSet method.
CatalogMetadata instances are only created internally by a Catalog object as it is being initialized. The Catalog instance will extract information about all the services defined by the catalog, and create one metadata object for each service. The information is compiled from a combination of local Carmenta Engine configuration files, ISO 19139 metadata files, and possibly metadata loaded from remote CS/W services.
The Catalog instance can also read ISO 19139 metadata from OGC GeoPackage files which uses the Metadata Extension.
Please see the Catalog Mechanism Overview for more information.
