MapQuery 0.1 Released

Via the OSGeo-Discuss list I learned about the release of the open source library MapQuery 0.1. Here's the official mapquery website.

What is MapQuery? "MapQuery is a pure javascript based library which builds upon OpenLayers, jQuery and jQuery UI to provide an easy to use webmapping library. It is meant for jQuery application developers who want to build Rich Internet Applications (RIAs) with maps. Currently it provides a few basic widgets to create functionality around a map and an easy API to write your own widgets."

Here's more on its goals: "MapQuery formally extends OpenLayers, it is similar in concept as GeoExt, but uses jQuery instead of Ext. The idea is to create a jQuery-style webmapping library which wraps around OpenLayers and extends it with functionality like layer managers, datagrids (NYI), legends etc. We try to make it easy to create a webmap-application with OpenLayers, without having to know all that OpenLayers has to offer.

We aim at jQuery developers more than on people who are already well-versed in OpenLayers. As such we will provide a few simple functions which (we think) will be enough for 90% of the use-cases. The other 10% is not actively pursued, though one could directly access OpenLayers and do some of the advanced stuff we're not providing."

Review of OpenLayers 2.10 Beginner’s Guide

Geoweb Guru offers a review of OpenLayers 2.10 Beginner's Guide by Erik Hazzard. From the review: "The book is written as a tutorial but also includes API reference material. The author does a good job of blending these two approaches. Each section of discussion and reference text is followed by "Time for action" (implementation example), "What just happened?" (explanation), and "Have a go hero" (exercise suggestions for modifying the code). [...] In contrast, the chapter on FireBug is welcome. It is only an introduction, but many web developers (myself included) tend to hack Javascript with nothing more than a text editor." We regularly mention OpenLayers.
