rasdaman is the pioneer Array DBMS enabling Big Datacube Analytics on spatio-temporal sensor, image, simulation, and statistics data through a high-level declarative datacube query language. Frontends supported include Leaflet, QGIS, ArcGIS, Python, R, openEO, and many more. Client-side parts are ... [More] LGPL for free use of rasdaman in open and closed applications; the server (a separate process) is GPL, implementing "life is a give and take". rasdaman community has been forked into open-source by rasdaman GmbH (dual-licence) and is co-led by Constructor University, the makers of Big Datacube standards: ISO Array SQL, ISO 19123-x, OGC CIS, WCS, and WCPS. rasdaman is official OGC Reference Implementation, official EU INSPIRE Good Practice and part of OSGeo Live.

The first NARS (Nested Arrays Research System) was designed and implemented in the early 1980s as a testbed for new ideas in APL, principally with nested arrays. A quarter of a century later, it's time to try again. The goal of this effort, as with the last one, is to foster new ideas about the ... [More] language and its implementation. Language ideas include new functions, operators, and datatypes. To aid in getting your ideas into an implementation, there will be a mechanism for telling NARS that a user-defined APL function represents a new primitive function, operator, or datatype. In order to experiment with your ideas for new extensions, all you need to know is how to write APL programs. [Less]

Kona is an open-source implementation of the K programming language (K3.2). If you're new to APL, you probably want this project. The K language was originally designed by Arthur Whitney and Kx Systems. It is an ASCII-based array language and a precursor to Kx's KDB, KDB+, and Q. Kona is unaffiliated with Kx.
