The AMICO Library was conceived in 1997, a full year before eXtensible Markup Language (XML) became a W3C recommendation, let alone a household name in cultural heritage institutions. Lacking a readily available standard for data encoding, the AMICO consortium invented a data format consisting of a field-prefix (such as OTY for Object Type) and the field delimiter “}~” to exchange information (AMICO) [2]. The burden of gathering data for the 27 required fields describing the artwork, plus the 16 required fields describing its surrogate, and exporting them in a non-standard format required many data contributors to dedicate full-time positions to the endeavor of sharing information.
