Properties that further clarify or quantify the output of the process (e.g. dynamic range, sensitivity, threshold, etc.). These can assist in the discovery of processes that meet particular requirements.

Useful properties of this process that do not further qualify the output values (e.g. component dimensions, battery life, operational limits, etc).

Classifiers useful for discovery of the process (e.g. process type, sensor type, intended application, etc.)

Persons or responsible parties that are relevant to this process (e.g. designer, manufacturer, expert, etc.)

Additional external online documentation of relevance to this process (e.g. user's guides, product manuals, specification sheets, images, technical papers, etc.)

A property that allows one to extend a document using a schema in a different namespace from the current schema.

A collection of time-tagged events relevant to this process.

Identifiers useful for discovery of the process (e.g. short name, mission id, wing id, serial number, etc.)

Short keywords describing the context of this document to aid in discovery.

A tag that identifies the language (e.g. english, french, etc.) for the overall document using a two-letters code as defined by ISO 639-1.

Legal constraints applied to this description (e.g. copyrights, legal use, etc.)

Overall security tagging of process description; individual tagging of properties can be done using extension element.

The time instance or time range during which this instance description is valid.

The value of the gml:boundedBy property describes an envelope that encloses the entire feature instance, and is primarily useful for supporting rapid searching for features that occur in a particular location.

The value of the gml:location property describes the extent, position or relative location of the feature.

The value of this property is a text description of the object. gml:description uses gml:StringOrRefType as its content model, so it may contain a simple text string content, or carry a reference to an external description. The use of gml:description to reference an external description has been deprecated and replaced by the gml:descriptionReference property.

The value of this property is a remote text description of the object. The xlink:href attribute of the gml:descriptionReference property references the external description.

Often, a special identifier is assigned to an object by the maintaining authority with the intention that it is used in references to the object. For such cases, the codeSpace shall be provided. That identifier is usually unique either globally or within an application domain. gml:identifier is a pre-defined property for such identifiers.

The gml:name property provides a label or identifier for the object, commonly a descriptive name. An object may have several names, typically assigned by different authorities. gml:name uses the gml:CodeType content model. The authority for a name is indicated by the value of its (optional) codeSpace attribute. The name may or may not be unique, as determined by the rules of the organization responsible for the codeSpace. In common usage there will be one name per authority, so a processing application may select the name from its preferred codeSpace.
