-The entity-level elements include the `dataTable`, `spatialRaster`, `spatialVector`, `storedProcedure`, `view`, and `otherEntity` elements, in addition to custom modules. Entities are usually tables of data (`dataTable`). Data tables may be ascii text files, relational database tables, spreadsheets or other type of tabular data with a fixed logical structure. Related to data tables are views (`view`) and stored procedures (`storedProcedure`). Views and stored procedures are produced by a relational database management system or related system. Other types of data such as raster (`spatialRaster`), vector (`spatialVector`) or spatialReference image data are also data entities. An `otherEntity` element should be used to describe types of entities that are not described by any other entity type. The entity-level elements are nested under `dataset` elements. Further information about entities may be found in the "eml-entity module" section in chapter 6.1.

 An entity-level annotation represents a precisely-defined semantic statement that applies to an entity. This semantic statement is used to associate precise measurement semantics with the entity. An entity-level `annotation` element is embedded in a containing entity-level element. The subject of the semantic statement is the entity-level element that contains the annotation. If the entity-level element contains an `id` attribute, then the subject should refer to the value of the `id` attribute. Each annotation consists of a `propertyURI` element and `valueURI` element, which respectively define a property and a value (object) that apply to the entity. Each URI should resolve to a controlled vocabulary that provides a precise definition, relationships to other terms, and multiple labels for displaying the statement. The associated `label` attribute for each URI can be used to display the property and value in a more readable format to users. Ideally, each `label` should be populated by a preferred label or label from a controlled vocabulary.
