	// It will be used when 'show.php' was called with 'submit=Export' but no 'exportFormat' parameter was specified.
	$defaultExportFormat = "RIS";


	// Specify whether export of data should be allowed via the refbase GUI for anyone who isn't logged in:
	// Note that this setting overrides the permission settings 'allow_export' and 'allow_batch_export' for
	// anonymous users ('userID=0') w.r.t. the *web* interface. E.g., with '$allowAnonymousGUIExport' set to

	$defaultFeedFormat = "RSS XML"; // possible values: "RSS XML", "Atom XML"


	// Specify who'll be allowed to see files associated with any records:
	// Set this variable to "everyone" if you want _any_ visitor of your database (whether he's logged
	// in or not) to be able to see links to any associated files. If you choose "login" instead, a
	// user must be logged in to view any files. Finally, use "user-specific" if you want to set this
	// permission individually for each user. Note that, setting this variable to either "everyone" or
	// "login" will override the user-specific permission setting for file downloads ("allow_download"
	// permission).
	$fileVisibility = "user-specific"; // possible values: "everyone", "login", "user-specific"


	// Specify a condition where files will be always made visible [optional]:
	// This variable can be used to specify a condition where the above rule of file visibility can be
	// by-passed (thus allowing download access to some particular files while all other files are
	// protected by the above rule). Files will be shown regardless of the above rule if the specified
	// condition is met. First param must be a valid field name from table 'refs', second param the
	// conditional expression (specified as /perl-style regular expression/ -> see note at the end of
	// this file). The given example will *always* show links to files where the 'thesis' field of the
	// corresponding record is not empty. If you do not wish to make any exception to the above rule,
	// just specify an empty array, like: '$fileVisibilityException = array();'. Use the "/.../i"
	// modifier to invoke case insensitive matching.
	$fileVisibilityException = array("thesis", "/.+/"); // e.g. 'array("thesis", "/.+/")'


	// Define what will be searched by "library_search.php":
	// refbase offers a "Library Search" feature that provides a separate search page for searching an
	// institution's library. All searches performed thru this search form will be restricted to
	// records that match the specified condition. First param must be a valid field name from table
	// 'refs', second param the conditional expression (specified as MySQL extended regular expression
	// -> see note at the end of this file). Of course, you could also use this feature to restrict
	// searches thru "library_search.php" by _any_ other condition. E.g., with "location" as the first
	// parameter and your own login email address as the second parameter, any "library" search would
	// be restricted to your personal literature data set. If you don't want to make any use of
	// "library_search.php", specify an empty array, like: '$librarySearchPattern = array();'
	$librarySearchPattern = array("location", "library"); // e.g. 'array("location", "IP� Library")'


	// Define the directory path that's used to save session data and to write any temporary files.
	// Usually, you can leave this variable as is. However, if you're on a hosted service, your
	// Internet Service Provider may have given you a specific session/temp DIR path which you may need
	// to specify here.
	$sessionTempDir = session_save_path(); // e.g. session_save_path(), or "/var/www/web12345/phptmp"
//echo  'tempdir: '.$sessionTempDir.'<br>';

	// The base DIR path to your default file directory:
	// I.e., the local path to the root directory where any PDF files etc. are stored. This must be a
	// valid path specification to a local directory that's accessible (read+write) by the server. As an
	// example, if you're using the Apache web server on a unix machine and if your default file
	// directory (named "files") is located on the root level of your refbase script directory (named
	// "refs") the path spec could be something like: "/usr/local/httpd/htdocs/refs/files/"
	// (IMPORTANT: if given, the base dir MUST end with a slash!)
	$filesBaseDir = getcwd()."/files/"; // e.g. "/usr/local/httpd/htdocs/refs/files/"
//echo  "dir: ".$filesBaseDir.'<br>';


	// The URL to the default file directory that you've specified in $filesBaseDir:
	// Any string within the 'file' field of the 'refs' table that doesn't start with "https://" or
	// "ftp://" will get prefixed with this URL. If your files directory is within your refbase root
	// directory, specify a *relative* path (e.g.: "files/" if the directory is on the same level as the
	// refbase php scripts and it's named "files"). Alternatively, if your files directory is somewhere
	// else within your server's DocumentRoot, you must specify an *absolute* path (e.g.: "/files/" if
	// the directory is on the uppermost level of your DocumentRoot and it's named "files"). If,
	// instead, you want to use *complete* path specifications within the 'file' field (e.g. because
	// your files are located within multiple directories), simply don't specify any URL here, i.e.,
	// keep it empty: '$filesBaseURL = "";'
	// (IMPORTANT: if given, the base URL MUST end with a slash!)
	$filesBaseURL = "files/"; // e.g. "files/"


	// Specify if files should be moved into sub-directories:
	//   - "never": files will always be copied to the root files dir (i.e. don't use any sub-directories)
	//   - "always": auto-generate new sub-directories if required (according to the naming scheme
	//               given in '$dirNamingScheme', see below)
	//   - "existing": only copy files into sub-directories if the sub-directory already exists
	$moveFilesIntoSubDirectories = "never"; // possible values: "never", "always", "existing"


	// Specify the naming scheme for auto-generated sub-directories:
	// (see comments for '$fileNamingScheme' for more info on supported placeholders)
	// Notes: - use slashes ('/' or '\') to separate between multiple sub-directories
	//        - you're allowed to use any characters between (or within) placeholders except the delimiters
	//          '<', '>' and ':'
	//        - handling of any non-ASCII chars will be controlled by '$handleNonASCIIChars' and unwanted
	//          characters can be excluded with the help of '$allowedDirNameCharacters' (see below)
	$dirNamingScheme = "<:firstAuthor:>/<:year:>"; // e.g. "<:firstAuthor:>/<:year:>"


	// Specify whether refbase shall rename uploaded files:
	// (note that if '$renameUploadedFiles' is set to "no", uploaded files will be blocked if they
	// contain any other characters than specified in '$allowedFileNameCharacters', see below)
	$renameUploadedFiles = "yes"; // possible values: "yes", "no"


	// Specify how to rename uploaded files:
	// Supported placeholders:

	// <:recordIdentifier:>, <:randomNumber:>
	// Notes: - some of these placeholders offer options (e.g. how many words/items shall be extracted
	//          from the given field), please see the refbase online documentation for more info about
	//          placeholders and their syntax: <https://placeholders.refbase.net/>
	//        - existing file extensions will be kept untouched by this naming scheme

	//          '<', '>' and ':'
	//        - handling of any non-ASCII chars will be controlled by '$handleNonASCIIChars' and unwanted
	//          characters can be excluded with the help of '$allowedFileNameCharacters' (see below)
	//        - it is strongly recommended to always include the '<:serial:>' placeholder in order to ensure

	$fileNamingScheme = "<:serial:>_<:authors:><:year:>"; // e.g. "<:serial:>_<:authors:><:year:>"


	// Specify how non-ASCII characters shall be treated in file/directory names:
	//   - "strip": removes any non-ASCII characters
	//   - "keep": keeps any non-ASCII characters (which, depending on your file system, may cause problems!)
	//   - "transliterate": attempts to transliterate most of the non-ASCII characters and strips all non-ASCII
	//                      chars that can't be converted into ASCII equivalents (this is the recommended option)
	$handleNonASCIIChars = "transliterate"; // possible values: "strip", "keep", "transliterate"


	// Specify all characters that will be allowed in file names:
	// In addition to the character conversion invoked by '$handleNonASCIIChars' (see above), this variable
	// allows you to further restrict generation of file names to a particular set of characters.
	// If '$renameUploadedFiles' is set to "no", uploaded files will be blocked if they contain any other
	// characters than specified here. If '$renameUploadedFiles' is set to "yes", any characters which
	// are not listed below will be removed from the generated file name.
	// (given expression must be specified as contents of a perl-style regular expression character class -> see
	// note at the end of this file; you can simply specify an empty string if you don't want any further character
	// conversion: '$allowedFileNameCharacters = "";')
	$allowedFileNameCharacters = "a-zA-Z0-9+_.-"; // e.g. "a-zA-Z0-9+_.-"

	$allowedDirNameCharacters = "a-zA-Z0-9+_-"; // e.g. "a-zA-Z0-9+_-"


	// Choose whether case transformations shall be applied to the file/directory names:
	//   - "no": don't perform any case tranformations (i.e, keep the file/directory names as is)
	//   - "lower": transform all characters to lower case
	//   - "upper": transform all characters to upper case
	// (note that case transformations will be always performed regardless of any other file/directory

	// here will appear as link within the explanatory text of 'import.php' pointing your users
	// directly to the CSA databases you have access to.

	// The search & replace actions defined in file 'includes/transtab_refbase_html.inc.php' will be
	// applied to the 'title', 'address', 'keywords' and 'abstract' fields (the list of fields can be
	// modified below, see '$searchReplaceActionsArray'). This feature is meant to provide richer text
	// capabilities (like displaying italics or super-/subscript) from the plain text data delivered by
	// the MySQL database. It works by means of "human readable markup" that's used within the plain
	// text fields of the database to define rich text characters. E.g., if you enclose a particular
	// word by substrings (like '_in-situ_') this word will be output in italics. Similarly, '**word**'
	// will print the word in boldface, 'CO[sub:2]' will cause the number in 'CO2' to be set as
	// subscript while '[delta]' will produce a greek delta letter. Feel free to customize this markup
	// scheme to your needs (the left column of the array in 'transtab_refbase_html.inc.php' represents
	// regular expression patterns matching the human readable markup that's used in your database while
	// the right column represents the equivalent HTML encoding). If you do not wish to perform any
	// search and replace actions, just specify an empty array, like: '$transtab_refbase_html =
	// array();'.
	include 'includes/transtab_refbase_html.inc.php'; // include refbase markup -> HTML search & replace patterns


	// Defines search & replace 'actions' that will be applied to all those refbase fields that are listed in the corresponding 'fields' element
	// upon WEB DISPLAY. Search & replace patterns must be specified as perl-style regular expression (including the leading & trailing slashes)
	// and may include mode modifiers (such as '/.../i' to perform a case insensitive match) -> see note at the end of this file.
	// If you don't want to perform any search and replace actions, specify an empty array, like: '$searchReplaceActionsArray = array();')

	// Note regarding the use of regular expressions:

	// Certain variables within this file expect you to enter search patterns as either "MySQL
	// extended" or "perl-style" regular expression. While regular expressions provide a powerful
	// syntax for searching they may be somewhat difficult to write and daunting if you're new to the
	// concept. If you require help coming up with a correct regular expression that matches your
	// needs, you may want to visit <https://grep.extracts.de/> for pointers to language-specific
	// documentation, tutorials, books and regex-aware applications. Alternatively, you're welcome to
	// post a message to the refbase help forum: <https://sourceforge.net/forum/forum.php?forum_id=218758>
