Health Data Platform Simple Sign-On Challenge

Description is leveraging a variety of open source infrastructure components including the Drupal 7 content management system, the CKAN data portal, the Solr search engine, and the community edition of the Virtuoso (as a RDF database and SPARQL endpoint query service). Going forward, the HDP team intends to realize an architecture similar to the Linked Data Integration Framework (LDIF) and leverage tools in the LOD2 stack where possible, beginning with Ontowiki to be used as Virtuoso editor, most likely followed by SILK for cross domain correlation. HDP would like to enable service requestors to be authenticated using WebID from the W3C. Some of the current and upcoming HDP infrastructure components support aspects of WebID functionality already while others do not. A number of WebID libraries are available, written in various languages .

This challenge winner will present a replicable open source virtual machine environment demonstrating how HDP components (with an initial emphasis on Virtuoso , Drupal 7 , CKAN , OntoWiki , and Solr ) can provide and/or consume WebID’s, contributing to simplified sign-on for humans and machines. The developer designs how their code might utilize each component as a WebID identity provider or relying party, presumably leveraging existing capabilities to the fullest extent possible. The end result will demonstrate seamless integration across a number of HDP components, without introducing any external service dependencies that couldn’t be operated by HHS. The contributed code will be given an open source license and managed by HHS on, with copyright and attribution to the developer(s) as appropriate.
