EXTENSIBILITY FOR WEB-BASED DIAGRAM VISUALISATION Russian patent published in 2014 - IPC G06F15/16 G06F9/06 G06F9/44 

FIELD: physics, computer engineering.

SUBSTANCE: group of inventions relates to an extensible architecture and data flow which enable a diagram update engine to launch custom code modules. A method to be executed at least in part in a computing device for extensible web-based diagram visualisation services comprises steps where, in response to receiving a request for a diagram including references to external data sources, providing the request to an update engine for determination of supported data sources and custom data modules for retrieving data from non-supported data sources which implement a predefined abstract class. Further, the method includes receiving a custom data module identifier from the update engine. The custom data module indicated by the identifier is also activated through said predefined abstract class and either data or an exception is received from the custom data module. If data are received, said data are redirected to the update engine.

EFFECT: reduced amount of data stored in a client device.
