Abstract:
1. A method of importing data to a computer-readable storage medium, comprising: receiving a first data set provided in a first format corresponding to a first data model; and processing the first data set to generate a second data set provided in a second format corresponding to a second data model, the first data model being incompatible with the second data model, wherein processing the first data set comprises: transforming the first data set to a third data set provided in a third format corresponding to a unified data model, the third format comprising a quadruple schema including subject, context, predicate and object, the unified data model comprising source info items, target info items, delta items and context items, transforming comprising: generating a source info item based on the first data set, the source info item representing an entity extracted from the first data set, the source info item associated with two or more attributes; generating a delta item based on the first data set, the delta item including a reference to the source info item and a context-based modification of the source info item; performing the context-based modification of the source info item; in response to performing the context-based modification, setting a property type of the source info item to point to the delta item, wherein the delta item is associated with a subset of the attributes; and storing the third data set to the computer-readable storage medium; and generating the second data set based on the third data set by exporting the third data set from the computer-readable storage medium, the exporting comprising at least one of: generating a resource based on a context-free info item of the third data set; generating a resource based on a delta item of the third data set, and associating a second resource based on a reference to an info item; and generating an association based on a context item of the third data set, and mapping a property type of the context item to a role.
