Bill Seddon, a software engineer at Lyquidity and XBRLQuery and creator of an open source XBRL processor, has created a resource page that supplements the information that I provide related to digital financial reporting. The page, Additional Information for the Digital Information Reporting Developer, targets the information needs of a developer looking to add support for Digital Financial Reports.
The page does not really add new stuff to the conceptual model, but rather its purpose is to bring together information across my sites that is relevant to a developer so there is no need to go hunting for that information.
However, it does try emphasise some important points that I seem to take for granted because I have been working with XBRL-based reporting for so long. Of course, once you learn of these points they are self-evident but until you make the connection certain things don't seem to make sense.
