Data management system, corresponding data management method and computer program

A computer-implemented data management method comprising:

• storing an additional dataset in a dataset memory included in a storing unit;
• determining whether the additional dataset includes dataset annotations descriptive of data comprised in said additional dataset;
• mapping each dataset annotation of the dataset annotations onto at least one predetermined annotation value stored in an annotation memory included in the storing unit;
• writing, in a metadata memory included in the storing unit, metadata representative of a result of the mapping, in relation to the additional dataset;
• wherein the mapping comprises
• encoding said each dataset annotation into a predetermined space to obtain a respective encoded dataset annotation;
• for said each dataset annotation that is encoded,
• determining a distance, with regard to a predetermined metric, between said each dataset annotation that is encoded and a closest encoded predetermined annotation value, each encoded predetermined annotation value being a result of encoding a respective predetermined annotation value into the predetermined space;
• if the distance that is determined is lower than a predetermined threshold, matching a respective dataset annotation with the respective predetermined annotation value corresponding to said closest encoded predetermined annotation value.

A non-transitory computer program product comprising instructions, which when executed by a computer, cause the computer to carry out a data management method, said data management method comprising:

• storing an additional dataset in a dataset memory included in a storing unit;
