This huge amount of high quality information would not be possible without the effort, specifically, of 'mappers', people who manually set the semantic relationships between the DBpedia ontology terms and the infoboxes in the spanish wikipedia.

These mappings would not be so productive without the logistical and financial support of the [Spanish Thematic Network of Linked Data|http://red.linkeddata.es/web/guest/home], which organized in November 2011 a [mappings marathon |http://www.fi.upm.es/?id=tablon&acciongt=consulta1&idet=932] attended for two days by 15 mappers. The effort paid off, as seen in Figure 1, as it managed to advance 12 positions (from 15 + english) in the ranking of semantic information generated from the information stored in the spanish wikipedia infoboxes.

As seen in figure 1, currently 80% of the spanish wikipedia infoboxes are mapped and, therefore, their information is available as Linked Data.
