KnowledgeLink is a powerful yet easy-to-use application for managing knowledge, ideas, and notes. It organizes documents in a hierarchy by branches whereby general categories nest more specific ones. Categories can easily be rearranged, added, and deleted. Each category contains a main document supporting rich text editing which allows fonts, formatting, and graphics to be embedded within the document. Files can be dragged from the Finder and copied into the category. Tagging is a central feature of KnowledgeLink. Within each document multiple tags may reside which associate text with structured data – similar to XML, but using a syntax that is less disruptive to the flow of plain text.
One of the built-in tags, flash, allows question tags to be embedded within the document with optional answer choices. The flash-card system allows these questions to be extracted from specified categories for quizzing.
