On 18 November, there will be an online meetup for the (German-speaking1) Apache Hop user community. Apache Hop2 is an open-source platform (under the Apache v2 license) that – in its own words and certainly in the hopes of some industry stakeholders – “aims to be the future of data integration.”
The registration form for the user meetup is available online. Participation is free of charge. The program also features a talk by Stefan Keller that specifically discusses spatial data integration and manipulation. In August, Stefan Keller has already hosted a webinar centered on Hop and he occasionally posts about Hop in the GEOWebforum3.
