The glossary of terms related to the active players in an artwork/construction in azulejo is the result of the workshop that ended AzLab#33. In it, a debate was promoted on the definitions below. These are not only operative tools used in the Az Infinitum – Azulejo Reference and Indexing System, but they are also a part of the ongoing Az.Thesaurus Project developed by the Rede de Investigação em Azulejo in partnership with the National Azulejo Museum.
