SGVizler integration for Plone 4
SGVizler is a library that can directly question SPARQL endpoint to visualize opendat in your site. This intregration of version 0.6 use dexterity type to be flexible with parameters.
Due to time limitation for the exercise this package is not done in the Plone 5 way.
- SGVizler 0.6
- Dexterity type to make the rendering
See the SGVizler documentation and screenshot below to see examples.
This add-on can be seen in action at the following sites:
TODO #Full documentation for end users can be found in the “docs” folder, and is also available online at http://docs.plone.org/foo/bar
As SPARQL works with prefix in its query, a good thing can be to overload the sgvizler-setup.js file.
SGVizler does AJAX request between domains. You need to configure your front proxy to accept data from domains where are SPARQL endpoints, id est you need to add connect-src and script-src provider in the Content-Security-Policy HTTP header.
Example with NGinx:
add_header X-Frame-Options "SAMEORIGIN"; add_header Strict-Transport-Security "max-age=15768000; includeSubDomains"; add_header X-XSS-Protection "1; mode=block"; add_header X-Content-Type-Options "nosniff"; add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-eval' 'unsafe-inline' http://endpoint.example.com http://sws.ifi.uio.no https://www.google.com; style-src 'self' 'unsafe-inline'; img-src 'self' 'unsafe-inline' http://mediaserver.example.com; media-src 'self' http://mediaserver.example.com http://videoserver.example.com; font-src 'self' 'unsafe-inline'; object-src 'self' http://endpoint.example.com http://sws.ifi.uio.no; connect-src 'self' http://endpoint.example.com http://sws.ifi.uio.no";
Notice that you need to open your server to google.com JS api (https://www.google.com/jsapi) until a better implementation of requirements in this project.
