Layout of installation
=======================

SeedDMS allows various kinds of installations with very individual layouts
on disc. The proposed layout till version 5.1.6 was as the following:

seeddms51x ---+--- data
              |
              +--- pear
              |
              +--- seeddms-5.1.x
              |
              +--- www -> seeddms-5.1.x

'data' contains all document files, the sqlite database (if used), the full text
data, the log files, and the cached preview images.

'pear' contains all PEAR packages including the four SeedDMS packages SeedDMS_Core,
SeedDMS_Lucene, SeedDMS_Preview, SeedDMS_SQLiteFTS.

'seeddms-5.1.x' are the sources of seeddms and 'www' being a link on it.

This layout has disadvantages when updating the source of seeddms, because
the directories 'conf' and 'ext' had to be moved from 'seeddms-5.1.x' to
'seeddms-5.1.(x+1)'. 'conf' was also visible over the web unless it was
protected by an .htaccess file. The .htaccess file has been shipped, but it
is far better to keep senѕitive data out of the document root in the first
place.

The new layout mostly retains that structure but uses more soft links to place
the local data outside of 'seeddms-5.1.x' which makes updating a lot easier
and moves the configuration out of the document root.
As MS Windows does not support soft links, this change will only apply to Linux/Unix
systems. MS Windows users just skip all the soft links and set seeddms-5.1.x
as the document root. The new layout is the following:

seeddms51x ---+--- data --+-- log
              |           |
              |           +-- cache
              |           |
              |           +-- 1048576
              |           |
              |           +-- ...
              |
              +--- pear
              |
              +--- conf
              |
              +--- seeddms-5.1.x
              |
              +--- seeddms -> seeddms-5.1.x
              |
              +--- www --+-- inc -> ../seeddms/inc
                         |
                         +-- op -> ../seeddms/op
                         |
                         +-- out -> ../seeddms/out
                         |
                         +-- views -> ../seeddms/views
                         |
                         +-- controllers -> ../seeddms/controllers
                         |
                         +-- styles -> ../seeddms/styles
                         |
                         +-- languages -> ../seeddms/languages
                         |
                         +-- webdav -> ../seeddms/webdav
                         |
                         +-- restapi -> ../seeddms/restapi
                         |
                         +-- pdfviewer -> ../seeddms/pdfviewer
                         |
                         +-- index.php -> ../seeddms/index.php
                         |
                         +-- ext

In order to convert to this layout you need to do the following in the seeddms51x
directory (replace the 'x' in '5.1.x' with the correct number):

ln -s seeddms-5.1.x seeddms
mv www/conf .
mv seeddms-5.1.x/ext www
cd www
rm inc op out views controllers styles languages webdav restapi pdfviewer index.php
ln -s ../seeddms/inc
ln -s ../seeddms/op
ln -s ../seeddms/out
ln -s ../seeddms/views
ln -s ../seeddms/controllers
ln -s ../seeddms/styles
ln -s ../seeddms/languages
ln -s ../seeddms/webdav
ln -s ../seeddms/restapi
ln -s ../seeddms/pdfviewer
ln -s ../seeddms/index.php
