/**
 * \file
 * \brief Configuration file of current data provider.
 *
 * This is the configuration file for the PHP OAI Data Provider.
 * Please read through the WHOLE file, there are several things, that
 * need to be adjusted.
 *
 *
 * The response may may be compressed for better performace:
 * - Compression : a compression encoding supported by the repository. The recommended values are those defined for the Content-Encoding header in Section 14.11 of RFC 2616 describing HTTP 1.1. A compression element should not be included for the identity encoding, which is implied.
*
 *
 * Some other used variables:
 *
 * - <B>$adminEmail</B>: the e-mail addresses of administrators of the repository.
 *
 * - <b>$repositoryIdentifier</b> : For a data provider there is only one. For repositories to comply with the oai 
 * format it has to be unique identifiers for items records.  Basically using domainname will be fine.
 * See: http://www.openarchives.org/OAI/2.0/guidelines-oai-identifier.htm.
 *
 * - <b>$SETS</b>: An array with key words . List of supported SETs.
 *
 * - <b>$METADATAFORMATS</b>: List of supported metadata formats. It is a two-dimensional array with keys.
 * Each supported format is one element of this array at the first dimension. 
 * The key is the name of a metadata format.  
 * The exact number of items within each format associated array depends on the nature of a metadata format.
 * Most definitions are done here but handlers themselves are defined in separated files because only the names of PHP script are listed here.
 * 		- metadataPrefix
 * 		- schema
 * 		- metadataNamespace
 * 		- myhandler
 * 		- other optional items: record_prefix, record_namespace and etc. 
 *
 * - <b>$SQL</b>: Settings for database and queries from database
 *
 * - <b>$DSN</b>: DSN for connecting your database. Reference PDO for details.
 *
 * The rest of settings will not normally need to be adjusted. Read source code for details.

 * Whether to show error message for dubug.

 * If set to TRUE, application will die and display query and database error message
 * as soon as there is a problem. Do not set this to TRUE on a production site,
 * since it will show error messages to everybody.
 * If set FALSE, will create XML-output, no matter what happens.

 * Identifier settings. It needs to have proper values to reflect the settings of the data provider.
 *
 * - $identifyResponse['repositoryName'] : compulsory. A human readable name for the repository;
 * - $identifyResponse['baseURL'] : compulsory. The base URL of the repository;
 * - $identifyResponse['protocolVersion'] : compulsory. The version of the OAI-PMH supported by the repository;
 * - $identifyResponse['earliestDatestamp'] : compulsory. A UTCdatetime that is the guaranteed lower limit of all datestamps recording changes, modifications, or deletions in the repository. A repository must not use datestamps lower than the one specified by the content of the earliestDatestamp element. earliestDatestamp must be expressed at the finest granularity supported by the repository.
 * - $identifyResponse['deletedRecord'] : the manner in which the repository supports the notion of deleted records. Legitimate values are no ; transient ; persistent with meanings defined in the section on deletion.
 * - $identifyResponse['granularity'] : the finest harvesting granularity supported by the repository. The legitimate values are YYYY-MM-DD and YYYY-MM-DDThh:mm:ssZ with meanings as defined in ISO8601.
