eml-resource
The eml-resource module contains general
information that describes dataset resources, literature resources,
collection resources, and software resources. It is intended to provide
overview information about the resource, including title, abstract,
keywords, contacts, and the links to associated metadata and data for
the given resource.
all datasets

Resource Base
Generic information about any resource that is being
described.
The 'ResourceBase' complexType contains information
that is inherited by each resource type that is being documented. The
subelements with the resource base are common to all
resources.
Please see the individual sub-fields for specific
examples.
The 'ResourceBase' element was introduced into EML
2.0.
Alternate Identifier
A secondary identifier for this entity
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.
VCR3465
As of EML 2.0.0
Identifier System
The system in which this id is
relevant
The computing 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
data management system.

Online Distribution Information
Distribution information for accessing the
resource online.
Distribution information for accessing the
resource online, represented either as a URL or as a series of
named parameters that are needed in order to
connect. The URL field is provided for the simple cases where a
file is available for download directly from a web server or
other similar server and a complex connection protocol is not
needed. The connection field provides an alternative where a
complex protocol needs to be named and described, along with
the necessary parameters needed for the connection.
Download site URL
A URL (Uniform Resource Locator) from which
this resource can be downloaded or information can be
obtained about downloading it.
A URL (Uniform Resource Locator) from
which this resource can be downloaded or additional
information can be obtained. If accessing the URL would
directly return the data stream, then the "function"
attribute should be set to "download". If the URL
provides further information about downloading the
object but does not directly return the data stream, then
the "function" attribute should be set to "information".
If the "function" attribute is omitted, then "download"
is implied for the URL function.
In more complex cases where a non-standard connection
must be established that complies with application
specific procedures beyond what can be described in the
simple URL, then the "connection" element should
be used instead of the URL element.

Connection Definition
The definition of a type of connection
that will be used in another location in the EML
document.
The definition of a type of connection
that will be used in another location in the EML
document. This only provides the definition of the
protocol and its parameters, but not the actual values
to be used to make the connection (instead, see the
connection element). The same connection definition may be
used by multiple connections (e.g., to download different files
from the same database), but each connection must provide or
reference a valid connection definition.
New in EML 2.0.0
Scheme Name
The name of the scheme used to identify this
connection.
The name of the scheme used to identify this
connection. The scheme name is qualified by its system attribute.
The scheme name implies a particular protocol for
accessing information from the connection. Applications must
have a knowledge of the scheme or be able to deduce the protocol
from the scheme description in order to effectively access data
over the connection. Many schemes will be unknown to client
applications. At some later point in time a registry for
connection schemes may be established in order to promote
application interoperability, and we may expand this portion of
EML to adopt a more comprehensive standard such as WSDL, but for
now this simpler description is provided.

Scheme System
The system in which this scheme name is
relevant
The computing system within which this
scheme name has relevance. This attribute qualifies the
scheme name in order to decrease the likelihood of scheme
name collisions when more that one EML user defines a
scheme name with the same name but different semantics.

Scheme Description
The description of the scheme used to identify this
connection.
The description of the scheme used to identify
this connection. The scheme name implies a particular protocol for
accessing information from the connection. Applications must
have a knowledge of the scheme or be able to deduce the protocol
from the scheme description in order to effectively access data
over the connection.
The metacat application protocol. Applications
must first log into metacat by sending an HTTP POST request
in http-url-encoded format with the parameters action, username,
and password. Action must be set to "login".
If authentication is successful, the metacat
server will respond with a session cookie. All future requests
should include the session cookie in the HTTP header. To
retrieve an object, the client then would send an HTTP POST
in http-url-encoded format, with an action parameter set to
"get" and the docid paramter set to the identifier for the
desired object. The response will either be an XML document
or a multipart-form-encoded response containing data.

Parameter Definition
The definition of a parameter that is needed to
properly use this connection scheme.
The definition of a parameter that is needed to
properly use this connection scheme. Each parameter has a name
and a definition that are used by applications to assess the type
of information needed for the request. Parameters may also set
default values that are used if a connection does not provide a
value for a parameter.

The definition of a parameter that is
needed to properly use this connection scheme. The
definition is used by applications to assess the type
of information needed for the request.

Default Parameter Value
The default value for a parameter that is
needed to properly use this connection scheme.
The default value for a parameter that is
needed to properly use this connection scheme. If a default
value is set, then it should be used for connections that
do not override the default with a connection-specific
value. This allows a definition to be established that
declares common information that might be shared by several
connections as default values. Parameter values provided
in the connection always override any default values
provided in the conneciton definition.
