Earlier experiments

Hello this is me Bharti, one of the developers at Mimas. I have earlier been involved in setup of DSpace installation on which the current ELO-Geo repository is based at the University of Nottingham. We got a unix (Solaris 10) based server setup with following details:
Basic configuration:
4GB RAM, 80GB or more Disk space, 2 processors

Then the basic software that were installed were:
1- Apache HTTP Server 2
2- Java JDK 6 or later
3- Apache Tomcat 7.0.12
4- PostgreSQL 8.4
5- PHP 5.3.6
6- Apache Maven 2.2.x
7- Apache Ant 1.7 or later

Once the above got installed I needed to begin the process of installing the DSpace repository software and MediaWiki.
8- DSpace
9- MediaWiki

The Nottingham folks were not much familiar with the last two and not a server expert, only had experience of installing on a local Windows server. Thus it was a challenge installing java based DSpace software on Solaris, and much tweaking was required.

I got finally DSpace running by following the steps which I coudln’t find anywhere, so thought to blog:

Change the domain name

Change from <original> to <new> in following files:

2) <user directory>/apache/conf/httpd.conf
3) <user directory>/elogeodspace/config/dspace.cfg

========================================================================

The initial URL is http://elo-geo.net/xmlui

In case there is a 503 error, the following commands need to be followed:

-bash-3.2$ <user directory>/postgresql-8.4.8/bin/pg_ctl -D <user directory>/postgresql-8.4.8/data -l logfile stop

 

-bash-3.2$ cd <user directory>/apache/bin/

 

-bash-3.2$ sudo ./apachectl stop

This will ask for the user password

 

-bash-3.2$ sudo ./apachectl start

 

-bash-3.2$ cd <user directory>/apache-tomcat-7.0.11/bin

 

-bash-3.2$ startup.sh

 

-bash-3.2$ <user directory>/postgresql-8.4.8/bin/pg_ctl -D <user directory>/postgresql-8.4.8/data -l logfile start

Then the task was to customise DSpace and Mediawiki according to Nottingham copy of ELO-Geo.

We as part of this project of Breaking barriers, will now proceed to complete the process and enhance as per the project outlines.

GeoKnowledge Project Begins

Introduction

Welcome to the blog for the JISC funded Open Educational Resources (OER) Rapid Innovation Project called Breaking Down Barriers: Building a GeoKnowledge Community with Open Educational Resources (OER).

Who is Involved?

This project is led by Mimas at the University of Manchester with Landmap and Jorum working together to host geospatial e-learning content using DSpace. The geospatial e-learning content originates from the outputs of a partnership project with Mimas and The University of Nottingham Geospatial Institute called E-Learning for the Open Geospatial Community (ELOGeo). The e-learning content within the Landmap Learning Zone has been sourced from geospatial companies and members of the academic community.

Project Aim and Objectives

The project aim is to use the Landmap and Jorum infrastructure to facilitate the sharing of OER in the geospatial community for a wide audience (researchers, students, local councils, Continuing Professional Development (CPD), industry). The objectives are:

  • To open-up 50% of the Landmap Learning Zone by relicensing e-learning materials using Creative Commons BY-NC-SA (as already agreed by the authors of the content)
  • In Jorum create a special GeoKnowledge Community repository using the DSpace API providing access to ELOGeo content (Figure 1).
