Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.
A general description of the statistical process and its outputs, and their evolution over time.

proportional
ISCED 5 programs are taught in secondary schools. they are special tertiary programs but we miss specific data on slitted personnel from ISCED 3. So we allocate the number of personnel and the expenditure proportionally according to the number of ISCED 5 students on total ISCED 5 + ISCED 3

At ISCED 6 and 7 a split into academic and vocational programs of expenditure and personnel is not possible. So we allocate the number of personnel and the expenditure proportionally according to the number of registered students into academic and vocational programs respectively at ISCED 6 and ISCED 7 level
