The topic of "Best Practices" (or just "Practices", since the determination of what is "Best" is highly subjective) falls under the jurisdiction of the XBRL International Best Practices Board (BPB). The BPB actively manages the production, dissemination, and continual improvement of products and resources that describe practices, methods, and processes for successful implementation, integration, maintenance, and usage of XBRL specifications.
**NEW** The Best Practice Board has launched a new series of educational webinars on the basics of XBRL
