A digital publishing platform enables users to create and organize notes associated with electronic, published documents. Sets of notes, each associated with a document, are uploaded to the publishing platform by notepad applications executing on user devices. Each set of notes has one or more notes, and each note includes a link to a location in the associated document. The publishing platform is configured to aggregate a plurality of sets of notes, combining the notes of the sets into a single set while maintaining their link to an associated document.

Notes aggregation across multiple documents

An education digital reading platform provides aggregation, management, and distribution of digital education content and services. The platform ingests content from a variety of content sources, transforms the content for web-based publication, and distributes the content to connected end-user devices via a network. The transformed content preserves the original page structure of the content document regardless of the original format of the content file. As the user experiences the content, the user's web browser regularly communicates with the platform for updating reading content and connected services. User-generated content such as notes are uploaded to the platform so that the user's user-generated content can be accessed from any of the user's registered devices. Moreover, the platform enables the user-generated content and other user activities to be optionally shared among friends, classmates, campus, or other groups, as part of an education social platform.

Electronic content management and delivery platform

An education digital reading platform provides pages of a document requested by a user, the pages including additional content layers associated with the requested content. The additional content layers including related content, user generated content, advertisement content and other services content offered by the digital reading platform. The requested content and additional content layers require processing capability on a web browser application. The amount of data associated with a page of a document may vary dramatically especially considering the additional layers of content associated with the pages. In order to permit the web browser application anticipate the processing needs associated with each page, the digital reading platform provides markers indicating a difference in processing requirements associated between two pages of a document. The markers enable the web browser request additional resources to provide a seamless user experience or enable the web browser application to request additional or fewer content layers.

Characterization of layered documents in HTML5 publishing

A method, a storage medium and a system for document content reconstruction are provided in a digital content delivery and online education services platform to enable delivery of textbooks and other copyrighted material to multi-platform web browser applications. The method comprises ingesting a document page in an unstructured document format. The method further comprises extracting one or more images and metadata associated with the images and text and fonts associated with the texts from the document page. In addition, the method comprises coalescing text into paragraphs and creating a structured document page in a markup language format using the extracted images, text and fonts rendered with layout fidelity to the original ingested document page.

Document content reconstruction

Embodiments provide a system for content distribution and protection. The system first receives an order from a user for a protected document. In response to a successful user authentication, the system generates an access code for the user to access the protected document. In response to a received user reading request, the system validates the access code for a reading session. The system then transfers a set of URLs for accessing a set of pages and associated metadata in the protected document to the user. The set of URLs are valid for a period of time. Responsive to a request for reading a next set of pages, the system again validates the access code for the session and transfers another set of URLs for accessing the next set of pages. The system also logs user activities related to the protected document.

Digital content distribution and protection

A notepad application enables users to create notes associated with electronic documents. The document, configured for rendering by an eReader browser application, is associated with a table of contents defining a plurality of sections of the document. The notepad application displays a note window associated with a section of the document within a user interface of the browser application. When a user generates a note in connection with the note window by indicating a location within the document, the notepad application adds the note to a note region in a note object that is associated with a section of the document defined by the table of contents. The notepad application then can access the note using the table of contents of the document.
