In some implementations, a method includes receiving a first data set that is stored using a first format, generating an info item based on the first data set, the info item representing an entity extracted from the first data set, generating a delta item based on the first data set, the delta item including a reference to the info item and defining a context-based modification of the info item, generating a second data set in a second format comprising the info item and the delta item, and storing the second data set to the computer-readable storage medium. |

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 delta item based on the first data set, the delta item including a reference to a source info item and a context-based modification of the source info item,in response to performing the context-based modification to the source info item, 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 attributes of the source info item, andstoring the third data set to the computer-readable storage medium; andgenerating the second data set by exporting the third data set from the computer-readable storage medium. |
