Implementation of an XML Schema describing a resource to be used in the Virtual Observatory Project. Based on "Resource Metadata for the Virtual Observatory", Version 0.8, February 2002 by Bob Hanisch et al.
Planetary Science Data Model: declaration of several metadata elements usedto define the coordinate system and type, the resolution, the coverage, thesampling in dataset and granule description.
A numeric grade describing the quality of theresource description, when applicable, to be used to indicate the confidence an end-usercan put in the resource as part of a VO applicationor research study.
See vr:ValidationLevel for an explanation of theallowed levels.
Note that when this resource is a Service, thisgrade applies to the core set of metadata.Capability and interface metadata, as well as thecompliance of the service with the interfacestandard, is rated by validationLevel tag in the capability element (see the vr:Service complextype).
The IVOA ID of the registry or organisation thatassigned the validation level.

Date associated with an event in the life cycle of theresource.
This will typically be associated with the creation or availability (i.e., most recent release or version) ofthe resource. Use the role attribute to clarify.
While this vocabulary is uncontrolled, recognized strings include "creation", indicating the date that the resource itself was created, and "update", indicating when theresource was updated last. The default value, "representative", means that the date is a rough representation of the time coverage of the resource.
Note that this date refers to the resource; dates describingthe metadata description of the resource are handled bythe "created" and "updated" attributes of the Resource element.

a description of how to call the service to accessthis capability
Since the Interface type is abstract, one must describethe interface using a subclass of Interface, denotingit via xsi:type.
Multiple occurances can describe different interfaces to the logically same capability--i.e. data or functionality.That is, the inputs accepted and the output provides shouldbe logically the same. For example, a WebBrowser interfacegiven in addition to a WebService interface would simply provide an interactive, human-targeted interface to the underlying WebService interface.
A tag name the identifies the role the interface playsin the particular capability. If the value is equal to"std" or begins with "std:", then the interface refersto a standard interface defined by the standardreferred to by the capability's standardID attribute.
For an interface complying with some registeredstandard (i.e. has a legal standardID), the role can bematch against interface roles enumerated in standard resource record. The interface descriptions inthe standard record can provide default descriptions so that such details need not be repeated here.
The version of a standard interface specification that this interface complies with. When the interface isprovided in the context of a Capability element, thenthe standard being refered to is the one identified bythe Capability's standardID element. If the standardIDis not provided, the meaning of this attribute isundefined.

Unless specifically disallowed by the context, applications should allow optional spaces to appear in an actual data value before and after the delimiter (e.g. "1, 5" when delim=",").
the default is " "; i.e. the values are delimited by spaces.
The data value represented by this type can beinterpreted as of a custom type identified by the value of this attribute.
If an application does not recognize thisextendedType, it should attempt to handle valueassuming the type given by the element's value.string is a recommended default type.

a description of standard space-time coordinate systems,positions, and regions.
This resource provides a mechanism for registering standard coordinate systems which other resources may reference aspart of a coverage descripiton. In particular, coveragedescriptions will refer to components of the STCdescriptions in this resource via an IVOA identifier. Itis intended that an application consuming such coveragedescriptions be able to semantically interpret theidentifier without resolving it. For this reason, once astandard STC description is registered with this resource type, updating the description is strongly discouraged.

A tag name the identifies the role the interface playsin the particular capability. If the value is equal to"std" or begins with "std:", then the interface refersto a standard interface defined by the standardreferred to by the capability's standardID attribute.
For an interface complying with some registeredstandard (i.e. has a legal standardID), the role can bematch against interface roles enumerated in standard resource record. The interface descriptions inthe standard record can provide default descriptions so that such details need not be repeated here.
The version of a standard interface specification that this interface complies with. When the interface isprovided in the context of a Capability element, thenthe standard being refered to is the one identified bythe Capability's standardID element. If the standardIDis not provided, the meaning of this attribute isundefined.

These four attributes represent the standard IVOA referencing system: internal (within the document) referencing through "id" and "idref", external referencing through Xlink, using only "type=simple" and "href".
The attributes ID_type and IDREF_type allow the author to list attributes of type ID, respectively IDREF, enabling readers to identify these attributes without having to refer to the schema. This is important in cases where documents are concatenated (e.g., in registries), raising the potential for non-unique IDs. The value of these attributes is a string of comma-separated attribute names.
