I’ve written quite a few articles about using Functional Programming (FP) with Magik on this site, and provided detailed code examples. However I haven’t yet put together an entire FP application. So let’s do that now. But rather than follow the same-old-same-old and write a standard GIS app, we’ll hook into one of the hottest […]

GeoSpatial Server (GSS) is an industrial-strength application that provides service-based integration technology for Smallworld products. Part of what puts the, “strength,” in, “industrial-strength,” is the fact it is deployed using Docker containers managed and orchestrated by Kubernetes. However deployment can be a complicated affair, and in many cases we simply want to develop services without […]

Starting in version 4.3, Smallworld GIS images/sessions can use a virtual VMDS by passing the -vvmds flag. For example: d:\smallworld\core\bin\x86\runalias.exe -vvmds -a d:\smallworld\cambridge_db\config\gis_aliases cambridge_db_open This is useful when you want to be able to restart from a known state without having to use checkpoints. It’s also extremely helpful when doing work with Alternatives. If, for […]

Smallworld GeoSpatial Server (GSS) is an industrial-strength application that allows Smallworld GIS to communicate with other systems in an industry-standard, open manner. It comes equipped with a variety of services out-of-the-box, but it’s real strength is that it can be customized to fit an enterprise’s exact needs. Unfortunately most custom implementations are tightly coupled to […]

If you’re familiar with JavaScript objects, then much of what I’m going to write will be familiar to you. These objects are different from what we’re used to in Smallworld GIS Magik. Like many OO languages, Magik uses class-based (or classical) inheritance while JavaScript uses prototypal inheritance. The difference is that instead of defining the […]
