Abstract: Source of information is a source of data from which a description is prepared. It is the basis of data selection in description. Compared with the original RDA, instructions on source of information in the new RDA have changed significantly in terms of concept, form and content. Instructions on source of information in the original RDA are for the source of the description data. Instructions on source of information in the new RDA are included in the instructions on data provenance. Instructions on data provenance are for the description of metadata work, which can be said to be an upgraded version of instructions on source of information in the original RDA. It embodies the orientation of linked data application and the concept of internationalization, openness and inclusiveness in the new RDA.

Key words: New RDA, Source of information, Data provenance, Metadata work
