Subject re:Marc tag is a metadata or is a coded template metadata
Thank you very much for those who contribute the information which is helpfull for me in developing my Digital Library project.
 
As now, I understand that Z39.50 is not a metadata but it is protocol compliant for searching biblographic database. but if it is, can anyone ensure is Marc tag  is a metadata or is a coded template metadata or it just a standard?
 
thanks
