Hyrax - BES Client commands

Client commands

Current core commands available with BES:

    <showHelp />

	* shows this help

    <showVersion />

	* shows the version of OPeNDAP and each data type served by this server

    <showProcess />

	* shows the process number of this application. This command is
	  only available in developer mode.

    <showStatus />

	* shows the status of the server

    <showConfig />

	* shows all key/value pairs defined in the bes configuration file.
	  This command is only available in developer mode.

    <showContainers />

	* shows all containers currently defined

    <showDefinitions />

	* shows all definitions currently defined

    <showContext />

	* shows all context name/value pairs set in the BES

    <setContainer name="container_name" space="store_name" type="data_type">real_name</setContainer>

	* defines a symbolic name representing a data container, usually
	  a file, to be used by definitions, described below
	* the space property is the name of the container storage and is
	  optional.  Defaults to default volatile storage. Examples
	  might include database storage, volatile storage based on
	  catalog information.
	* real_name is the full qualtified location of the data container, for example the full path to a data file.
	* data_type is the type of data that is in the dataset.  For netcdf files it is nc. For some container storage the data type is optional, determined by the container storage.

    <setContext name="context_name">context_value</setContext>

	* set the given context with the given value. No default context
	  are used in the BES

    <define name="definition_name" space="store_name">
	<container name="container_name">
	    <constraint>legal_constraint</constraint>
	    <attributes>attribute_list</attributes>
	</container>
	<aggregate handler="someHandler" cmd="someCommand" />
    </define>

	* creates a definition using one or more containers, constraints
	  for each of the containers, attributes to be retrieved from
	  each container, and an aggregation. Constraints, attributes,
	  and aggregation are all optional.
	* There can be more than one container element
	* space is the name of the definition storage.  Defaults to
	  volatile storage. Examples might include database storage.

    <deleteContainer name="container_name" space="store_name" />

	* deletes the specified container from the specified container
	  storage (defaults to volatile storage).

    <deleteContainers space="store_name" />

	* deletes all of the currently defined containers from the
	  specified container storage (defaults to volatile storage).

    <deleteDefinition name="definition_name" space="store_name" />

	* deletes the specified definition from the specified container
	  storage (defaults to volatile storage).

    <deleteDefinitions space="store_name" />

	* deletes all of the currently defined defintions from the
	  specified container storage (defaults to volatile storage).

Added commands for dap enabled servers:

If you are serving up OPeNDAP data responses (DAS, DDS, DataDDS) then you will have loaded the dap commands in your configuration file. Here are the available commands in the dap module.

    <showCatalog node="node_name" />

	* Shows catalog information, including contents if a
	  container. If node is not specified then the root node
	  information is returned. If node is specified then that nodes
	  information is returned.</LI>

    <showInfo node="node_name" />

	* Shows catalog information for just that node, the root node
	  if no node is specified. If the node is a container the contents
	  are not displayed.</LI>

    <get type="das|dds|dods|ddx" definition="def_name" returnAs="returnAs" />

	* dds: request the data descriptor structure
	* das: request the data attributes
	* ddx: request the data attributes and data descriptor structure
	  returned as an xml document
	* dods: request for the data stream, this output is an octec binary
	* stream which requires the analysis by the client dods library

    <setContext name="errors">dap2|xml|html|txt</setContext>

	* set the context 'errors' to dap2 in order to have all
	  exceptions and errors formatted as dap2 error messages in
	  the response.
