We built a semantic social network based on Drupal and the Apache Solr indexer to manage and dynamise large volumes of educational resources for tens of thousands of nationwide users.

The principal challenge was to implement advanced concepts in the semantic website by Drupal

INTEF is a unit dependent of the Ministry of Education (Spain) and responsible for the integration of technologies and communications in the non-university stages of the education system. The Procomún educational website is a Ministry of Education, Culture and Sports (MECD) initiative, which is based on the Proyecto Agrega (http://agrega.educacion.es/). It is a digital initiative that focuses on a website that integrates didactic objects and teaching experiences, forming an intelligent, social and widely-available / easily accessible website.

In this educational community, the Autonomous Communities can find and create in this educational community structured didactic material and a standardized classified form (LOM-ES) for students and teachers to download and use directly.

The main objectives of this project were to:

• Construct a “semantic layer” upon an existing platform, capable of providing the contents daily with relevant information obtained automatically from other related contents  and from information obtained from the opinions of users and the uses made of the website.

• Extend the services offered by the web through work with structured websites and linked to the rules of semantic web data.

• Develop a faceted search engine that allowed users to find learning objects across multiple criteria or facets based on their own reasoning.

• Provide a social network for teachers researchers and students to connect, share knowledge and establish relationships, offering great interactivity and semantic and use recommendations.
