Interface CatalogEntry

All Known Subinterfaces:

TypeEntry, TypeEntry

All Known Implementing Classes:

DefaultTypeEntry, WMSLayerCatalogEntry

public interface CatalogEntry

The Catalog Entry contains all the metadata entities used to describe one resource. More specifically, an object of this class contains a collection of metadata entities which together describe the associated resource for the purpose of discovery. This collection of metadata entities is usually only a subset of all the MetaDataEntity that exists for the associated resource.

One or more of the metadata entities usually directly reference the associated resource, and provide the basic information needed to locate and subsequently access that resource, either directly or through an access service. When applicable, one or more of the included metadata entities may specify the spatial location of the resource. The spatial location could be defined by a (minimum bounding) rectangle, and/or by a polygon bounding the ground area covered. Perhaps the spatial location could be defined by any OpenGIS geometry. For example, the spatial location of a feature describing a single point could be defined by that point.

If the resource is a dataset, several of the included metadata entities may define the types of data included in the dataset, plus the quality of that data.

NOTE: The specification Catalog Services 1.1.1 does not specify the methods of the CatalogEntity interface. The methods in this interface were inferred from reading the abstract catalog specification: Catalog Services section 3.1.2
