The challenges of providing portals for
diverse user communities
Our institutional challenge is to deliver
information to people outside of our (climate)
community so they can make informed
analyses and decisions that lead to solutions
● non-climate scientists
● decision makers
● organizations and businesses
tools need to be part of that work flow

The birth and life of the IFRC Maprooms
If floods relate to unusual rainfall, does this map tell where rainfall is unusual?
No! Need for historical context: Compare current 6-day forecast with historical 30-year average same 6-day period
Need for a new dataset

Search
● The maprooms are designed to be found and understood by a search
engine
But we also have our RDF-based search
● The maprooms are semantically tagged using RDFA
● We have an RDF-crawler with inferencing to gather metadatata
● uicore (maproom clientside) interface code talks with a SPARQL service
point (sesame server)
● Function documentation
● comprehendible terms
● faceted browser
All very much works-in-progress
