Not required for CQL and searchTerms additional information on the query type indication of the level of support for facets, which provide analysis of search results giving counts and facilitate selection within a result set repeatable structure for each facet type supported and delivered by a server name of a facet additional information on a facet indicates whether or not the server will accept a request to limit the facet count for a particular facet limit on facet counts imposed by the server an indication that a server will accept limits other than its own default an offset into the list of counts to allow paging the offset applied by the server if no instruction is given in the query an indication that a server will accept offsets other than its own default indicates that a server will supply the facets in a sorted order on request indicates that a server will supply results in a sorted order on request repeatable sequence for each sort key supported by a server name of sort key to be used in queries indicates that a server supports results sorting in ascending or descending sequence or both and indicates its default behavior indicates that a server supports case sensitive or case insensitive facet sorting or both and indicates its default behavior indicates the default applied by the server if the data being sorted lacks the necessary data element indicates the character encoding conventions accepted by the server for Unicode characters beyond U+007F that are not valid in a URI. indicates the types of records used by a server to deliver results indicates the defined schemas used by a server to deliver or to sort results information on the support of stylesheets by a server indication that the server will supply a stylesheet reference in the response for the client to do the rendering upon request indication that the server will apply a stylesheet to a result set prior to sending sequence of URLs pointing to the stylesheets supported for server rendering list of URIs of extensions supported which are returned in extraRecordData and extraResponseData only if requested in extraSearchData includes server defaults, fixed settings and supported elements list of response formats supported, e.g. sru+xml, rss+xml, atom+xml (httpAccept parameter in request) name identifier used in a request to indicate the response format URI identifying response format's definition URL for a locaion where the response format's definition may be found media types for which this response format is valid indicates support for diagnostic sets other than SRU name of diagnostic set URI identifying diagnostic set's definition URL for a locaion where the diagnostic set's definition may be found an indication that the owner of the database has also made the explain document and thus this is the definitve description. an indication of the person or institution that created this document address of the server which provides the service, usually a name which will resolve to a correct IP address number of the port used for connection to the service name of the database accessed by the service described authentication details that are required to access this server name of the protocol used to access the server at this URL endpoint indication of the latest version of the protocol supported for accessing the server name of the protocol used to access the database URL to a WSDL file which describes the server description of the database that is accessed by the server name of the database free text information about the database including but not limited to coverage, strengths, size, quality and recency name of a person or organization credited with the creation of the database name and address of a person to contact for information on the database indicates completeness of the database information on the origin, development and evolution of this database indication of the languages covered in the database indication of limitations that may affect access to the database or reuse of its records list of terms from a controlled vocabulary indicating the topical coverage of the database URL links to alternative accesses to this database information on the software and other technical components used by this database date and time on which this explain document was last created or modified URL linking to another server, indicating that the explain document was not created on this server but harvested date and time on which this explain document was harvested recognized scheme of pre-defined indexes an index or access point that can be used in queries of data in a database indicates the record structure supported by a server indicates whether 'string' or 'xml' or both is or are supported list of escapes supported. String and XML are reserved definitions indicates whether 'packed' or 'unpacked' or both is or are supported list of packing supported. Packed is a reserved definition information on the schemas employed for sorting and presenting data from the database indicates that if an element is not given in a search, the server will apply this default value indicates that only one setting for an element is possible indicates that the server supports an element publically available token which can be used for access publically available authentication elements which can be used for access an indication that authentication is required for access to the database by this method indication of the number of records in the database date and time in format ISO 8601 (YYYYMMDDHHMMSS) of the latest addition or modification in the database index name supported by the server indication of equivalent alternative names for the index within other sets includes server defaults, fixed settings and indication of support for the index identifier of the index other than its title indicates that this index is used by the server in search indicates that this index is used by the server in scan indicates that this index is used by the server in sort indicates the content schemas for a record structure supported by a server name of the schema with an indication of language identifier of this schema name of this schema URL linking to a copy of this schema indicates that this schema may be used for sorting indicates that records may be retrieved from the database using this schema name of index scheme with an indication of language name of a recognized scheme of pre-defined indexes or a URI identifier in the form of a URI pointing to a definition of the index scheme indicates the default text that should be provided if language is not specified 2 letter code from RFC 1766 indicating the language of the text string of one or more 2 letter codes from RFC1766 indicating the languages covered in the database indicates that a server supports sorting of facets alphabetically or by record count or both and indicates its default behavior indicates that a server supports results sorting in ascending or descending sequence or both and indicates its default behavior indicates that a server supports case sensitive or case insensitive facet sorting or both and indicates its default behavior
