SLAP xs slap XML Schema used to describe the capabilities of a service instance conforming to the Simple Line Access Protocol (SLAP). An abstract capability that fixes the standardID to the IVOA ID for the SLAP standard. See vr:Capability for documentation on inherited children. The capabilities of an SLAP service implementation. The category indicating the level to which this service instance complies with the SLAP standard. Allowed values are "minimal" and "full". See definitions of allowed values for details. The category specifying where the data accessed by the service originally came from. Allowed values are "observational/astrophysical", "observational/laboratory", "theoretical" The hard limit on the largest number of records that the query operation will return in a single response. If not specified there is no predefined hard limit on the number of records in a query response. A set of queryData parameters that is expected to produce at least one matched record which can be used to test the service. The value should include all parameters required for the test query but should exclude the baseURL and the REQUEST parameter. The allowed values for indicating the level at which a service instance complies with the SLAP standard. The service supports all of the capabilities and features of the SLAP protocol identified as "must" in the specification. In brief, this includes: * implementing the GET interface, * WAVELENGTH, REQUEST for input query, * ssldm:Line.wavelength.value and ssldm:Line.title for output fields * supports the "FORMAT=METADATA" metadata query. The service supports, at a minimum, all of the capabilities and features of the SLAP protocol identified as "must" or "should" in the specification. The defined categories that specify where the line data originally came from, i.e., the type of data collections to which the service provides access. Lines observed and identified in real spectra of astrophysical observations by different instrument/projects Lines observed and identified in real spectra of laboratory measurements Servers containing theoretical spectral lines A query to be sent to the service, e.g., a test query. Spectral range in meters to be used to constrain the query of spectral lines. Fully specified queryData test query formatted as an URL argument list in the syntax specified by the SLAP standard. The list must exclude the REQUEST argument which is assumed to be set to "queryData". VERSION may be included if the test query applies to a specific version of the service protocol. If queryDataCmd is used to form a query, the default value of WAVELENGTH specified above is not used; if the test query requires WAVELENGTH it should be included directly in queryDataCmd. This value must be a string in the form of name=value pairs delimited with ampersands (&). A query may then be formed by appending to the baseURL the request argument, "REQUEST=queryData&", followed by the contents of this element. Spectral range in meters to be used to constrain the query of spectral lines Minimum wavelength in meters to be used to constrain the query of spectral lines Maximum wavelength in meters to be used to constrain the query of spectral lines
