A Drupal ++ platform for semantic web biomedical data – that’s how Sudeshna Das describes eXframe, a reusable framework for creating online repositories of genomics experiments. Das – who among other titles is affiliate faculty of the Harvard Stem Cell Institute – is one of the developers of eXframe, which leverages Stéphane Corlosquet’s RDF module for Drupal to produce, index (into an RDF store powered by the ARC2 PHP library) and publish semantic web data in the second generation version of the platform.
“We used the RDF modules to turn eXframe into a semantic web platform,” says Das. “That was key for us because it hid all the complexities of semantic technology.”
One instance of the platform today can be found in the repository for stem cell data as part of the Stem Cell Commons, the Harvard Stem Cell Institute’s community for stem cell bioinformatics. But Das notes the importance of the reusability aspect of the software platform to build genomics repositories that automatically produce Linked Data as well as a SPARQL endpoint, is that it becomes easy to build new repository instances with much less effort. Working off Drupal as its base, eXframe has been customized to support biomedical data and to integrate biomedical ontologies and knowledge bases.
