This document discusses integrating user feedback data with geospatial data through a CKAN extension. It describes how user feedback is a form of citizen science data that can help validate other collected data. Examples are shown of integrating feedback on INSPIRE and ECOPotential maps. A live demo is provided and future development of a JavaScript API and widget is discussed to simplify integration of user feedback for programmers with basic JavaScript knowledge.

Geospatial User Feedback
• User feedback is a form of CitSci data and complements
producers data quality. Since CitSci projects are conducted
by communities, they can validate the data collectively by
providing feedback on the data others have captured

How to enter new feedback
• A development for the NextGEOSS project

Examples of GUF integration:
INSPIRE discovery portal
• Looking for “Corine” and “Spain”, this is the first record
that shows previous feedback entries

Examples of GUF integration:

Future of GUF
• At the moment:
– The programmer retrieves directly the feedback items related with a
resource using the NiMMBus API and gets the response encoded in
XML. The programmer should generate a presentation by
himself/herself. This provides him/her full control on how the content
is shown in the screen but it requires considerable more knowledge
on JavaScript programming, including XML parsing and AJAX calls.
• Future:
– Develop a JavaScript API and a widget
• very simple to integrate
• relative low level of flexibility
– It will be useful for fast an simple integration requiring only basic
knowledge on JavaScript
