DESCRIPTION:A knowledge graph is a network that interconnects concepts\, ob
 jects\, or events according to domain specific relationships and terminolo
 gy. Spatial knowledge graphs model locations and how they are spatially re
 lated to each other according to semantic properties and are useful for he
 lping to automate the integration of geographic data across silos. Informa
 tion systems used to make decisions often have different pictures of the g
 eographies (i.e. people\, places\, and infrastructures) they respectively 
 cover. Within a single area\, different programs collect and store differe
 nt geographic data in siloed systems at different times\, leading to discr
 epancies and duplication of effort. This also results in decisions based o
 n incomplete and out-of-date geographic data (e.g.\, spatial distribution 
 of population and resources).\n\nGeoPrism Registry is an open-source Commo
 n Geo-Registry (CGR) implementation that utilizes spatial knowledge graphs
  to provide a single source of truth for managing geographic data over tim
 e across multiple information systems and data sources. It is used to publ
 ish\, access\, and manage changes over time to hierarchies and geospatial 
 data for geographic objects such as administrative divisions\, infrastruct
 ure and other relevant physical features. \n\nGeoPrism Registry uses geo-o
 ntologies to define semantic properties and relationships that implement s
 patial knowledge graphs using a graph database. Changes to attribute value
 s\, relationships\, and geographies are managed for different time periods
 . Historical views of data can be generated for any time period. The appli
 cation has been released under the Lesser General Public License (LGPL) an
 d was developed using only open-source components including OpenJDK\, Mapb
 oxGL\, PostgreSQL\, OrientDB\, Solr\, GDAL\, and GeoServer.\n\nThis talk w
 ill demonstrate how spatial knowledge graphs defined in GeoPrism Registry 
 using FOSS4G tools can:\n1. contextualize data from different sources in b
 oth time and space\,\n2. use geographic objects as the common link between
  data sources\,\n3. facilitate trend analysis\, and\n4. aggregate data acc
 ording to different hierarchies\n\nSupport for the development of GeoPrism
  Registry was provided by the Bill and Melinda Gates Foundation via the Di
 gital Solutions for Malaria Elimination (DSME) Project and the DSME Commun
 ity. The DSME project uses geo-enabled information systems to improve the 
 efficiency and effectiveness of malaria surveillance\, program planning\, 
 and intervention.
