a Number of those operations, or their names b Number of those interfaces, or their names
One or more interfaces shall be specified that, when all are implemented by one archive server instance, provide operations that support the functionality specified in the
following subclauses, namely providing operations allowing:
a Get service metadata b Get schema
c Input and delete object d Get object
e Get coverage optional f Get map optional
5.3.2 Get service metadata
The archive function interfaces shall provide one or more operations that together meet the following service metadata retrieval requirements:
a This operations shall allow clients to retrieve service metadata for the archive server instance.
b This operations shall allow retrieving service metadata that describes all the operations implemented by the archive server instance, providing information needed
for a client to request those operations and use the operation responses. c This operations shall allow retrieving a list of all the data and metadata types that
can currently be retrieved from or input into the archive server instance. This operations shall not require retrieving some metadata from all of the data andor
metadata groups currently stored by the archive server instance. Also, this operations should not require retrieving the complete data schema for all of the data
and metadata types that can be stored.
d The service metadata outputs shall be encoded in XML. e The output contents and formats shall be specified using XML Schema, and those
schemas should be based on GML wherever applicable. f This operations shall be required implementation by all compliant archive server
instances.

NOTE That is, an archive server instance which does not fully implement this operations shall not
be considered compliant with the specification. All the image archiving server components implemented in the OWS 1.2 testbed shall implement this operations.
This get service metadata operations should be as similar as practical to both the a GetCapabilities operation of the WFS, WRS, or WOS.
