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

Embodiments of the invention provide a system and a method for providing consistent user experience in eReading applications. The system extracts a set of attributes of browsers and platforms on which an eReading application is running. The system receives a target eReading application performance. The system adjusts behavior of the eReading application to compensate for the difference between the extracted set of attributes and the target eReading application performance.

Cache management in HTML eReading application

An application gateway enables controlled communication between application components within a browser based environment while maintaining a level of isolation of the individual application components. A dispatching API wrapper and a listening API wrapper are registered for each of a plurality of application components. The registered API wrappers are used to send and receive communications from the associated application components. For example, a first application component can dispatch an action to a second application component via the first application component's dispatching API wrapper. The second application component can receive the action via the second application component's listening API wrapper. As another example, a first application component can dispatch an event that broadcasts a state to other application components via the first application component's dispatching API wrapper. A listening API wrapper of at least one other application component receives the state and may perform other functions dependent on the state.

Application gateway in a browser based environment

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.
