WNET.org and Brooklyn web developer Tierra Innovation Inc. promoted their WordPress CMS Toolkit at the regional WordCamp NYC last week. Their first four freely available, open-source plugins for WordPress are available online now and “lots more” are coming, says Tierra President Jamie Trowbridge. Also coming are templates for a content management system abstracted from the ones used by WNET.org to build 50 sites for its shows, stations and projects, Trowbridge tells Current. Outside of West 33rd Street, Dallas’s KERA recently used the toolkit to build a site for KXT-FM, its new sister station (“Music to the Core”), and Chicago’s WTTW created one for its coproduction with Brian Boyer, Retirement Revolution. Among the available WP plugin modules: Audio Playlist Manager, for embedding a series of clips in a website, and WPDB Profiling, which helps a site-builder find causes of undue server loads. Soon to be released are Billboard Manager, which creates a Flash slide show; prettyPhoto Gallery and two other plugins.
