-===== Dependencies =====+The latest version of the documentation is always available in [[https://svn.met.no/viewvc/metamod/trunk/docs/html/index.html?view=co|the code repository]].
  
-This software depends on the following external software which is not part +===== Installing METAMOD 2.10 or later =====
-of the METAMOD 2.x distribution:+
  
-  * Linux operating system. METAMOD 2.x should work on other UNIX-like operating systems, but this is not tested. +The installation procedure is evolving for each new release, constantly seeking to make it more automated and painless. For instructions, read the official installation guide for the required release:
-  * Mail system +
-  * PostgreSQL database system. Tested on version 8.1 +
-  * Apache 2.x web server with PHP 5.x installed, including pgsql, libxml +
-  * Perl v5.8 with the following Perl modules: File::Copy, File::Path, XML::Simple, XML::LibXML, XML::LibXSLT, DBI, DBD::Pg, Geo::Proj4, Mail::Mailer, PDL, PDL::NetCDF, LWP::UserAgent +
-  * NetCDF software +
-  * ImageMagick +
-  * curl, php5-curl (for fimex functionality)+
  
-==== Ubuntu 8.04 (Hardy) ====+  * [[https://svn.met.no/viewvc/metamod/trunk/docs/html/installation.html?view=co|bleeding edge]] 
 +  * [[https://svn.met.no/viewvc/metamod/branches/2.12/docs/html/installation.html?view=co|2.12]]

-  * XML::XPathContext +
-  * PDL::NetCDF +
- +
-===== Directory structure ===== +
- +
-The top METAMOD 2.x directory  +
-is divided into one subdirectory for each module (base, search, upload and +
-quest). In addition, one subdirectory (app) contains an example application. +
- +
-The module directories shares a common structure. During installation of an +
-application, a new directory is created (the target directory), and all module +
-directories are merged into this target directory. In each module directory +
-there is a htdocs subdirectory. The htdocs directories for all the selected +
-modules are in the same way merged into one htdocs subdirectory in the target +
-directory.  To avoid name collisions, the actual HTML and PHP files etc. are +
-contained within subdirectories of the htdocs directory. For example, all such +
-files are contained in the directory htdocs/sch for the METAMODSEARCH module, +
-and htdocs/upl for the METAMODUPLOAD module. On the target directory, there +
-will be a htdocs directory containing both the sch and the upl subdirectories. +
-Some htdocs subdirectories may be shared among several modules. For example, +
-the METAMODBASE module and the METAMODQUEST module both have files in the adm +
-subdirectory. Special care must be taken for these files to avoid name +
-collisions. +
- +
-Each module directory must also contain a file 'filelist.txt' which +
-lists all files comprising the module. +
- +
-The app directory contains one subdirectory for each application. In each +
-of these application directories there must be a configuration file called +
-'master_config.txt', and a 'filelist.txt' file containing a list of files +
-that are specific for the application (image files, style sheets etc.). +
-Application directories may also be found outside the METAMOD 2.x source tree. +
- +
- +
-===== System Configuration ===== +
- +
-The following values should be configured in the **php.ini** file  +
- +
-<code> +
-track_errors = On +
-upload_max_filesize = 100M +
-post_max_size = 100M +
-</code> +
- +
-The following values are an advantage to use in **postgresql.conf**: +
- +
-<code> +
-random_page_cost = 2.0 +
-</code> +
- +
-===== Configuration ===== +
- +
-The source files within the METAMOD 2.x directories contain a variety of file +
-types (PHP, Perl, XML, HTML/XHTML, CSS and shell-script files, some of +
-them with embedded SQL). The source files are not intended to be used +
-directly, but must be modified and copied to a target directory tree before +
-the application can run. The reason for this is to apply a unified +
-configuration method for all the different file types. +
- +
-An application directory must contain a file, **''master_config.txt''**, which is the master configuration file for the application: +
- +
-This file contains lines as follows: +
- +
-  VARNAME = VALUE +
- +
-'VARNAME' must be all uppercase letters [A-Z], underscore or digits. Any number +
-of white space characters may separate 'VARNAME' and '=', and also '=' and +
-'VALUE'. 'VALUE' starts with the first non-whitespace character and ends with +
-the last non-whitespace character on the line. Additional lines may be +
-appended to 'VALUE' immideately after the initial 'VARNAME = ...' line. Such +
-lines must start with a space character. No whitespace are removed from such +
-appended lines. +
- +
-VALUEs may be empty, which sometimes indicate that some aspect of the software +
-is turned off. An empty value is indicated by having no characters (or only +
-whitespace characters) after the '=' character. +
- +
-In addition, comment lines, starting with '#', may be found. Blank lines are +
-ignored. +
- +
-In the source files, all text strings like: +
- +
-  [==VARNAME==] +
- +
-will be substituted with the corresponding value when the files are modified and +
-moved to the target directory. Such text strings may also be found within 'VALUE' +
-strings, and they will be substituted as appropriate. +
- +
-One variable is mandatory in master_config.txt: TARGET_DIRECTORY. This is the +
-directory name of the target directory, the top level of the target directory +
-tree. +
- +
-The following variables are used to select the modules that will comprise the +
-application. They also identify the absolute path of the source directory for +
-each module: +
- +
-  METAMODBASE_DIRECTORY +
-  METAMODSEARCH_DIRECTORY +
-  METAMODUPLOAD_DIRECTORY +
-  METAMODQUEST_DIRECTORY +
- +
-If any of these variables are missing, the corresponding modules will not be part +
-of the application. +
- +
-Each application delivering data to a database (an application with the +
-METAMODUPLOAD and/or the METAMODQUEST module) must have a short acronym +
-that uniquely identify the application for the database. This acronym is +
-included in the master_config.txt file as the value of variable APPLICATION_ID. +
- +
-===== Installation ===== +
- +
-To install an application, the following installation script (located in the top +
-METAMOD 2.x directory) should be run with one argument: +
- +
-   update_target.pl application_directory +
- +
-The argument is the absolute or relative path of the application directory, the +
-directory containing the master_config.txt file for the application. +
- +
-For each module selected by the configuration file, there is a **''filelist.txt''** list +
-of files in the corresponding module directory. The installation script will copy +
-all the files in these lists to the target directory tree (given by +
-TARGET_DIRECTORY in the configuration file). In the same way, files in the +
-application specific ''filelist.txt'' file (located in the application directory) +
-will be copied to the target directory tree. If any file name collision occur +
-between the module file lists and the application file list, the file in the +
-application file list is used. Thus, it is possible to substitute any file +
-in any module with an application specific file, although this mechanism is +
-primarily meant for image files, style sheets etc. Name collisions between files +
-from different modules are supposed not to occur. +
- +
-While copying the files, the script will perform all substitutions prescribed +
-in the configuration file. The script will only copy files that are +
-modified later than the corresponding target files (or the target file does not +
-exist). Directories will be created as needed. +
- +
-Some files (e.g. binary files like image files etc.) are not intended for this +
-kind of modification. To avoid substitution on such files, the file names must +
-be prepended with '=' in ''filelist.txt''. +
- +
-The file pathes in each ''filelist.txt'' file must all be relative to the +
-corresponding top module directory (or the application directory). The copied +
-files will keep these relative pathes on the the target directory. +
- +
-**Multiple target files** +
- +
-It is possible to use the configuration file to produce several target files +
-from a single source file. This is done using the special directives: +
- +
-  !substitute_to_file_with_new_name sourcefilepath => targetfilepath +
-  !end_substitute_to_file_with_new_name +
- +
-The 'sourcefilepath' must be a relative file path found in one of the +
-''filelist.txt'' files, and 'targetfilepath' must also be a relative file path, +
-but it is not required to exist in any ''filelist.txt'' file. The source file +
-(given by 'sourcefilepath') will be modified and copied to the target file +
-(given by 'targetfilepath') using the ordinary substitution directives in +
-the configuration file. In addition to these substitutions, any substitution +
-directive between the '!substitute_to_file_with_new_name' directive and the +
-corresponding '!end_substitute_to_file_with_new_name' directive will be +
-performed. Note that these substitution directives will not affect any of the +
-other files produced by the installation script. +
- +
-By using these special directives several times for the same source file, +
-and varying the target file name between each use, several target files are +
-produced from the same source file, and they will have different content +
-depending on the in-between substitution directives found for each target +
-file.+
