The Mindjet Labs has just released a new Mindjet MindManager Pro 6 OPML Editor. The Editor enables users to open, edit, and save Outline Processor Markup Language (OPML) files in MindManager Pro 6. The editor also reads and writes the Simple Sharing Extensions to OPML introduced by Microsoft under a Creative Commons License.
Originally conceived by Dave Winer, founder of Userland Software, OPML (Outline Processor Markup Language) is, according to WikiPedia, "an XML format for outlines. Originally developed…as a native file format for an outliner application, it has since been adopted for other uses, the most common being to exchange lists of RSS feeds between RSS aggregators. The OPML specification defines an outline as a hierarchical, ordered list of arbitrary elements. The specification is fairly open which makes it suitable for many types of list data."
