The laws of supply and demand dictate that there will be no end to the growing commercial value for a limited number of great works of art; and as long as those who deal in the commercial aspects of art — galleries, art dealers, auction houses and the media — are involved as the arbiters of criteria in judging art, market prices will continue to rise and art forgery will proliferate.

Provenance (from the French provenir, 'to come from/forth') is the chronology of the ownership, custody or location of a historical object.[1] The term was originally mostly used in relation to works of art but is now used in similar senses in a wide range of fields, including archaeology, paleontology, archives, manuscripts, printed books and science and computing.
All the paintings appear to have originated with one man, an obscure French collector-turned-dealer named Giulano Ruffini. The works appear to have had next-to-no provenance, save that they came from the collection of French civil engineer André Borie. Ruffini insists he never suggested they were the real deal, and that eager dealers were the ones to declare his paintings Old Master originals.

Interoperability is a design goal of most recent computer science provenance theories and models, for example the Open Provenance Model (OPM) 2008 generation workshop aimed at "establishing inter-operability of systems" through information exchange agreements.[38] Data models and serialisation formats for delivering provenance information typically reuse existing metadata models where possible to enable this. Both the OPM Vocabulary[39] and the PROV Ontology[40] make extensive use of metadata models such as Dublin Core and Semantic Web technologies such as the Web Ontology Language (OWL). Current practice is to rely on the W3C PROV data model, OPM's successor.[41]
The notion of intellectual property—the idea that artists’ works belong to them—dates at least to medieval Europe, though history records examples of the concept as early as ancient Greece. It had taken hold sufficiently during the Renaissance for Michelangelo to take umbrage when his work was misattributed. It was reported that when he discovered that another artist was receiving credit for sculpting the famous Pietà (now in St. Peter’s Basilica in Rome), Michelangelo returned with his chisel and added his signature across the centre of the sculpture, on the prominent sash across Mary’s upper body (in Italian): “Michelangelo Buonarroti, Florentine, made this.”
