Abstract: A data visualization metrics explorer can be provided using JSON and hypertext. When an element of a grid row is selected, a new metrics explorer blade can be opened. A filter can be applied so that only information associated with the selected element is presented. Additional filters may also be applied to the data that is displayed. Progressive, iterative filtering can occur. The links between blades can be specified using JSON and hypertext. Multi-linking and re-use of individual JSON files can be performed by linking the JSON files together into a web. The web of visualization can be used to construct a web of visualization actions enabling data visualization exploration.

Abstract: Visual indicators are added to each page or screen of an e-book display to provide a visual cue to help the user associate the visual cue with content of the book and go back to previously read contents using the visual cue. The visual indicators are icon-like graphic objects placed at a desired location on the page. They have shapes that are simple, easy to remember, and easily distinguished from each other. In one example, each visual indicator has an outline shape such as a circle, triangle, square, etc. which starts out empty with no fill. As the user moves forward in the book the current visual indicator is progressively filled with a pattern. Once the visual indicator is fully filled the next visual indicator is selected and the process repeats. The visual indicators are automatically generated for each page based on the position of the page within the e-book.

Abstract: A method for managing digital files, including the steps of generating a main hash for a new file, searching for a matching main hash of any existing file in storage, if a matching main hash is found, then stop from further processing the new file, but if no match is found, then generating a sub-hash for a sub-part of the new file, and searching for a matching sub-hash of any existing file in storage; if no match of the sub-hash is found, then processing the entire new file and saving the processed new file in the storage, if a matching sub-hash for a sub-part of an existing file is found, then processing only the remaining part of the new file that is not the sub-part for which the sub-hash is generated, and retrieving the matching sub-part of the existing file; and saving the processed remaining part of the new file and the retrieved sub-part of the existing file in storage as a combined digital file.

Abstract: A method for managing printing a hard copy of a work from a digital copy of the work, including the steps of a content provider of the digital copy of the work dynamically generating a standardized two-dimensional barcode when the digital copy of the work is produced for a user acquiring rights to the digital copy of the work, the barcode containing a unique URL of the content provider and being embedded in a portion of the digital copy of the work where digital rights management protection is omitted; and a print shop scanning the barcode from the digital copy of the work provided by the user to be readily linked to the content provider, and obtaining authorization and royalty information for printing the hard copy of the work for the user.
