moduleName: eml-entity

moduleDescription: 
          
            
              The eml-entity module - Entity level information within datasets
            
          
        

recommendedUsage: This module is used to describe data
        entities.

standAlone: Only when 'otherEntity' is used.

tooltip: Alternate Identifier

summary: A secondary identifier for this entity

description: An additional, secondary identifier for this
            entity. The primary identifier belongs in the "id" attribute, but
            additional identifiers that are used to label this entity, possibly
            from different data management systems, can be listed
            here.

example: VCR3465

tooltip: Entity name

summary: The name of the entity name

description: The name identifies the entity in the dataset:
            file name, name of database table, etc.

example: SpeciesAbundance1996

tooltip: Entity description

summary: General description of the entity and its
            contents

description: Text generally describing the entity, its type,
            and relevant information about the data in the
            entity.

example: Species abundance data for 1996 at the VCR LTER
            site

tooltip: physical descriptors

summary: Description of the physical format of the entity
            

description: Information on the physical format of this entity.
            Each logical entity can be serialized in one or more physical
            formats, which can be described here.  For each physical format,
            provide a "physical" element that describes the format and how
            to obtain that version.  Two physical elements MUST describe
            the same entity precisely (i.e., after obtaining and parsing
            the physical data stream described under each physical element,
            one MUST end with an identical logical entity).
            For more information see the eml-physical module.

tooltip: coverage descriptors

summary: Information on the geographic, spatial and temporal
            coverages used in this entity.

description: Information on the geographic, spatial and temporal
            coverages used in this entity.  Please see the eml-coverage module
            for more information.

tooltip: method descriptions

summary: 

description: Information on the specific methods used to collect
            information in this entity.  Please see the eml-methods module for
            more information.

example:

tooltip: Additional Information

summary: Any extra information pertitent to the
            entity.

description: This field provides any information that is not
            characterized by the other entity metadata
            fields.

example: Multiple sampling events represented

tooltip: Semantic Annotation

summary: A precisely-defined semantic statement about this entity.
            

description: An annotation represents a precisely-defined semantic
                  statement that applies to this entity.  This semantic statement
                  is used to associate precise measurement semantics with the
                  entity.  Each annotation consists of a propertyURI and valueURI,
                  which define a property and a value that apply to the entity.
                  The associated labels can be used to display the property and
                  value to users.  Each URI is resolvable to a
                  controlled vocabulary that provides a definition, relationships
                  to other terms, and multiple labels for displaying the statement.

tooltip: Attribute List

summary: The list of attributes associated with this
                entity.

description: The list of attributes associated with this
                entity.  For more information see the eml-attribute
                module.

tooltip: Constraint

summary: 

description: Description of any relational constraints on '
                this entity.  For more information see the eml-constraint
                module.

tooltip: Entity type

summary: Contains the name of the type for this
                entity.

description: The entityType field contains the name of the
                entity's type. The entity's type is typically the name of the
                type of data represented in the entity, such as "photograph".
                This field is used only if this is an 'other' entity and you
                want to specify the kind of "other" entity this
                is.

example: Photograph

tooltip: Other Entity

summary: Descriptor of single data entity in a dataset of a type
        not specifically described in eml.

description: The other entity element is a descriptor of a
        not-otherwise-defined entity in the dataset, identified by its name.
        The element can contain information about the entity's basic identity,
        its temporal, geographic and taxonomic coverage, and its
        type.

example: Photograph of rocky intertidal plot 12 from Santa Cruz
        Island

tooltip: Identifier System

summary: The system in which this id is
                    relevant

description: The information management system within
                    which this identifier has relevance. Generally, the
                    identifier would be unique within the "system" and would be
                    sufficient to retrieve the entity from the system. The
                    system is often a URL or URI that identifies the main entry
                    point for the information management
                    system.

example: 
                    http://knb.ecoinformatics.org/knb/

tooltip: Base Entity descriptors

summary: Basic information about an entity common to all entity
        types.

description: The EntityGroup defines the common structure for
        descriptions of any type of entity, including the name and attributes
        of the entity. The term entity is used in the sense of an entity in a
        relational model. The most common entity is a table, something with
        columns and rows, but can also represent an image or other type of
        data. See 'eml-attribute' for descriptions of the required attribute
        fields.
