This is an example on how to query the datasets on the wiki using Semantic Media Wiki (SMW) queries. The queries refer to the Special:Categories and Special:Properties defined in the wiki.

Example: Get a list of datasets with archive coral (limit to 10)

{{ #ask: 
[[Category:Dataset_(L)]] 
[[IncludesPaleoData_(L).FoundInMeasurementTable_(L).IncludesVariable_(L).MeasuredOn_(L)::<q>[[Category:Coral]]</q>]]
 | mainlabel=Datasets
 | format=broadtable
 | limit=10
}}

Example: Get a list of datasets with archive coral and observation d18O

{{ #ask: 
[[Category:Dataset_(L)]] 
[[IncludesPaleoData_(L).FoundInMeasurementTable_(L).IncludesVariable_(L).MeasuredOn_(L)::<q>[[Category:Coral]]</q>]]
[[IncludesPaleoData_(L).FoundInMeasurementTable_(L).IncludesVariable_(L).ProxyObservationType_(L)::D18O]]
 | ?IncludesPaleoData_(L)=PaleoData
 | format=broadtable
 | limit=10
}}

Example: Search and map the records for the Atlantic

{{#ask: 
[[Category:Location_(L)]] 
[[CoordinatesFor.IncludesPaleoData_(L).FoundInMeasurementTable_(L).IncludesVariable_(L).MeasuredOn_(L)::<q>[[Category:Coral]]</q>]]
[[Ocean::Atlantic]]
 | ?Coordinates
 | ?CoordinatesFor
 | ?Name_(L)
 | showtitle=off
 | maxzoom=14
 | minzoom=1
 | limit=500
 | template=LiPDLocation
 | format=leaflet
}}
