GADM is a spatial database of the location of the world's administrative areas (or adminstrative boundaries) for use in GIS and similar software. Administrative areas in this database are countries and lower level subdivisions such as provinces, departments, bibhag, bundeslander, daerah istimewa, fivondronana, krong, landsvæðun, opština, sous-préfectures, counties, and thana. GADM describes where these administrative areas are (the "spatial features"), and for each area it provides some attributes, foremost being the name and variant names.

The jLayout JavaScript library provides layout algorithms for laying out components. A component is an abstraction; it can be implemented in many ways, for example as items in a HTML5 Canvas drawing or as HTML elements. The jLayout library allows you to focus on drawing the individual components instead of on how to arrange them on your screen.

The library currently provides four layout algorithms: border, which lays out components in five different regions; grid, which lays out components in a user defined grid, flex-grid which offers a grid with flexible column and row sizes, and flow which flows components in a user defined direction. A jQuery plugin to lay out (X)HTML elements is also available.

XSLTJSON is an XSLT 2.0 stylesheet to transform arbitrary XML to JavaScript Object Notation (JSON). JSON is a lightweight data-interchange format based on a subset of the JavaScript language, and often offered as an alternative to XML in—for example—web services. To make life easier XSLTJSON allows you to transform XML to JSON automatically.

XSLTJSON supports several different JSON output formats, from a compact output format to support for the BadgerFish convention, which allows round-trips between XML and JSON. To make things even better, it is completely free and open-source.
