Collaboration capabilities of the GeoChronos platform will be achieved through the use of a model-driven architecture that allows for new data sources, and new applications to be quickly integrated into the platform by scientists. Integrating tools, data, and computing resources into a single platform will enable the automation of scientific workflows. The platform will provide tools for developing a web accessible spectral library, allowing Earth observation scientists to contribute to, and query a database of spectra. The spectral library will support rich metadata necessary for interpreting observed spectra. The overall goal is for the platform to become a one stop shop for Earth observation science.

Recently I had a project to integrate Elgg and Moodle. In an earlier post I discused the single sign on feature where users could login to Elgg and be automatically signed into Moodle when they clicked the link to Moodle pages.

In addition I needed to make the themes for Elgg and Moodle match. This is quite challanging. As of Moodle 1.9 course layout still uses some tables which make duplicating a similar layout to Elgg difficult.

In addition I had to make the top navigation/toolbar match between Elgg and Moodle. This was interesting because the menus in the toolbar were generated dynamically by Elgg based on the user identity. To accomplish this I created an AJAX based solution using the Yahoo UI library. I created a custom Elgg view that just provided the toolbar without any additional content. This was added on the fly to the top of the Moodle pages for a seamless experience.

We recently connected ELGG and Moodle using the Moodle Network feature. This provides an API to allow single-sign-on between multilple servers. This can include multiple Moodle server, or other servers that support the MNET API.

For this project we needed ELGG to be the primary authority so users would sign into ELGG first, and be able to access Moodle by clicking a link that would provide the proper information to Moodle to log them into Moodle. 

To the end user the integration is seamless. They click a link and the Moodle site can appear as integrated into the ELGG site. This requires some fiddling with the HTML and CSS to get Moodle and ELGG themes to be consistent. I address this in another post.
