A recent discussion at the [https://apachecon.com/acah2020/tracks/jena.html ApacheCon 2020 Jena Track] let to the organization of this GeoSpatial Semantic Web Use Cases workshop to further learn more about our users and the application of Semantic GeoSpatial Web technologies and in particular GeoSPARQL and to help build a dedicated community around the topic of spatial data on the web.

It's almost 14 years since we have introduced the first official geospatial features to the Jena project and we are now fortunate to offer an OGC compliant GeoSPARQL module along with the regular Apache Jena release cycle which be used to build spatial data applications and publish spatial linked data on the web.

If you are interested in use cases or applications that makes use of spatial data and analyses for the web this event is for you. Presentations are not limited to the use of the latest release of the Apache Jena Spatial module or the Apache Jena project for that matter but any use of linked spatial data and GeoSPARQL on the web.

====<i>Foreword</i>====

<H3>Consolidation and extension of the semantic web with spatial-temporal data models and open APIs</h3>
<i>George Percivall, Geospatial Information Engineer and Apache Software Foundation</i>

This workshop is a timely opportunity to build on the call for consolidation of previous developments of ontologies, linked data, and knowledge graphs.   Apache projects, such as Apache Jena, serve as a basis for consolidation and advancement of the semantic geospatial web. Previous experiments demonstrated building blocks toward a system of real-world feature identifiers and the use of APIs for resource access. More work is needed to establish best practices related to negotiation between varied representations of a feature, observations related to a feature, and for expressing and mediating between varied content from a given resource.  Further developments of the GeoSPARQL standard for space and time as well as  with non-geographic spatial data have been identified.  Standards in Discrete Global Grid Systems along with implementations of DGGS provide new methods for linked open spatial data.  Use cases for the future semantic geospatial web will consolidate use of spatial concepts, extend to discrete space, and enhance linked data and property graphs for spatial data in time.

===Standards for Spatial Data on the Web - Linda van den Brink===
 W3C and the Open Geospatial Consortium (OGC) have been collaborating through a joint working group to develop and maintain vocabularies and best practices that encourage better sharing of spatial data on the Web; and identify areas where standards should be developed jointly by both W3C and OGC. The talk will give a short overview of how this collaboration works, what came out of it, and possible future developments.
 
 Linda van den Brink worked (10+ years) as a geospatial standards expert at Geonovum, a national geospatial standards body for the Netherlands.
