INTRODUCTION

This software has been developed to create the MEDIN Portal
(portal.oceannet.org) by the GeoData Institute
(www.geodata.soton.ac.uk) on behalf of the MEDIN partnership
(www.oceannet.org).

INSTALLATION
------------
The server-side software is written in Python 2.6 and is designed to
run on any WSGI or CGI compliant HTTP server. It is recommended that
it be run under CGI for development environments and a persistent WSGI
environment for production deployment (e.g. www.modwsgi.org).

The software has the following dependencies:

 * Python 2.{6,7}

 * libxml2 2.7.* (http://www.xmlsoft.org/) compiled with support for
   Python

 * GDAL 1.7.* (http://www.gdal.org) compiled with support for OGR

 * TMS/WMS + Python Mapnik 0.7.0 (http://www.mapnik.org/) compiled
   with support for GDAL + Python

 * sqlite3 (http://www.sqlite.org/) compiled with threadsafe support

 * pysqlite 2.5.6 (http://pypi.python.org/pypi/pysqlite)

 * SQLAlchemy 0.7.6 (http://www.sqlalchemy.org/)

 * rdfextras 0.2 (http://pypi.python.org/pypi/rdfextras/0.2)

 * RDFLib 3.2.1 (http://pypi.python.org/pypi/rdflib/3.2.1)

The CGI script is deploy/portal.cgi and the WSGI application is found
in deploy/portal.wsgi. Your web server should be configured
appropriately to invoke the required script.

In addition, the 'python' directory must be added to the HTTP server's
PYTHONPATH location so that the calling python process can locate the
application's modules. 

Likewise the contents of the html directory should be made available
at the web server's root web location.

CONFIGURATION
-------------
The application is configured by setting the PORTAL_ROOT environment
variable to the absolute filesystem path of the package's root
directory. 

Genetic portal configuration is done by copying the
etc/portal.cfg.example file to etc/portal.cfg and editing the contents
as required.

Specific configuration of the portal spatial services is done by
editing the files in the templates/config directory.

Additionally, the online EPSG Geodetic Parameter Database
(http://epsg-registry.org) should be updated by running the
`bin/epsg-update.py` script when required (e.g. on a daily basis as a
cron job):

    PYTHONPATH=./python python ./bin/epsg-update.py ./data/epsg-registry.sqlite

The above command assumes the script is run from the root distribution
directory: the PYTHONPATH variable provides access to the required
packages provided by the distribution.

The vocabulary cache should be updated in a similar way using
`bin/vocab-update.py`. This script uses a newline separated text file
as input to define a number of both local file-based and online
vocabularies. These vocabularies are then cached in a SQLite database
specified as a command line argument along the following lines:

    PYTHONPATH=./python python ./bin/vocab-update.py \
    --vocabularies ./data/vocabularies/vocab-list.txt \
    ./data/vocabularies.sqlite
