Embodiments include a system for matching an element of a source schema to an element of a target schema. The system includes a processing unit and a communication unit. The processing unit may be configured to: identify a sample data item of the element of the target schema; match a part of the sample data item to a part of a sample instance of the source schema; and match the element of the source schema to which the part of the sample instance of the source schema belongs to the element of the target schema. The communication unit may be configured to: provide the sample data item through an interface and receive the sample instance of the source schema.
