The record

Product: Strabon is a spatiotemporal RDF store for storing linked geospatial data that changes over time and querying it with extensions of SPARQL.
Spatial data: It supports spatial datatypes and serializes geometric objects in OGC WKT and GML formats.
Spatial queries: It offers spatial selections and joins, spatial functions, and support for multiple Coordinate Reference Systems.
Temporal data: It supports valid time for triples, temporal functions, and modeling temporal domains and concepts such as events and facts that change over time.
Query languages: Strabon supports stSPARQL for querying data represented in stRDF, and a subset of GeoSPARQL for static geospatial RDF data.
GeoSPARQL scope: The site says implementation of the other GeoSPARQL components is underway.
Technology: Strabon extends Sesame, now called RDF4J, and uses its components to manage thematic, spatial, and temporal data stored in a backend RDBMS.
License: Strabon is released under the Mozilla Public License.
Download: The download page directs users to the project's GitHub repository for the latest version.
Documentation: The download page links to an stRDF and stSPARQL tutorial and provides an stSPARQL reference describing spatial and temporal extension functions.
Support: The project lists separate mailing lists for users and developers; the developers channel also receives check-in messages.
Use case: The site describes Strabon being used to store and query timeseries data in a MELODIES use case.
