Required format: Drop-down list based on the Nomisma standard (http://nomisma.org/).
This field identifies the personal, ethnic, or institutional authority under which the weight is issued. It is frequently used to indicate the ruling monarch appearing on a weight. E.g. “Antiochus IV Epiphanes”, “Nerva”, “Justinian I”, “Philippus”, “Patricius of Megalopolis”.

Required format: Drop-down list based on the Nomisma standard (http://nomisma.org/).
This field identifies the place of manufacture or the issuing city of the weight.
E.g. “Athens”, “Rome”, “Constantinople”.

Required format: Drop-down list based on the Nomisma standard (http://nomisma.org/).
This field identifies the official name(s) of the weight, based on its legend, its symbols, its shape, its mass, or any other available evidence.

Required format: Drop-down list based on the Nomisma standard (http://nomisma.org/).
This field defines the physical material from which the weight is made. E.g. “Lead”, “Bronze”, “Stone”.

Required format: Drop-down list based on the Nomisma standard (http://nomisma.org/).
This field defines the technique of manufacture of the weight. E.g. “Cast”, “Carved”, “Struck”.

Required format: Drop-down list. To be defined in the Nomisma standard (http://nomisma.org/).
This field defines the shape of the weight. E.g. “Square”, “Truncated sphere”, “Polyhedron”, “Pig”.

Required format: Numeric data. The dimensions are typically expressed in centimetres (cm), but can occasionally be expressed in inches (in)—in this case, the relevant field should be filled in, and the dimensions will be converted to centimetres automatically.

Length: One of the three dimensions of the weight (the x-coordinate in a 3D Cartesian coordinate system).

Width: One of the three dimensions of the weight (the y-coordinate in a 3D Cartesian coordinate system).

Height: One of the three dimensions of the weight (the z-coordinate in a 3D Cartesian coordinate system).

Required format: Numeric data.
This field registers all the measurements of the mass of the weight since it was found or acquired. The mass of the weight is typically expressed in grams (g), but can occasionally be expressed in grains (gr)—in this case, the relevant field should be filled in, and the mass will be converted to grams automatically. To each measurement can be linked a date of measurement (format YYYY-MM-DD), the reference for this measurement (free text), and technical explanations about the physical conditions of the object (fragmented and/or cleaned). If several measurements are registered, one mass should be selected as the reference mass of the weight.

Required format: Drop-down list.
This field enumerates all the symbols that are shown on the weight. E.g. “Dolphin”, “Horse”, “Female head”, “Bust of Emperor”, “Imperial crown”.

Required format: Free text based on the EpiDoc standard (https://sourceforge.net/p/epidoc/wiki/Home/).
This field describes the inscriptions or markings (incised or in relief) placed on the weight as part of the production process or after the production.

Required format: Drop-down list based on the Nomisma standard (http://nomisma.org/), as defined by “Usure et corrosion: Tables de référence pour la détermination de trouvailles monétaires = Abnutzung und Korrosion: Bestimmmungstafeln zur Bearbeitung von Fundmünzen” ( Bulletin IFS ITMS IRMS 2, 1995, Suppl.) (https://www.muenzfunde.ch/downloads/supplement_1995.pdf).
This field measures the degree of degradation of the weight due to chemical reaction with its environment. E.g. “K1. Little to no corrosion”; “K5. Extremely corroded”.

Required format: Drop-down list based on the classical periodization of ancient and Byzantine times.

This field identifies the period of production of the weight, i.e.: “Archaic and Classical periods (700–338 BCE)”; “Hellenistic period (338–31 BCE)”; “Early Roman Empire (31 BCE – 284 CE)”; “Late Roman Empire (284–476 CE)”; “Early Byzantine Empire (476–843 CE)”; “Middle Byzantine Empire (843–1204 CE)”; “Late Byzantine Empire (1204–1453 CE)”.

If necessary, select several (contiguous) periods: e.g. “Archaic and Classical (700–338 BCE)” + “Hellenistic (338–31 BCE)” for a weight dating to the 4th or the 3rd c. BCE.

Required format: Free text.

This field is intended to justify the suggested dating for the weight, by explaining the main chronological arguments and referring to modern scholarship.

Required format: Drop-down list based on the Nomisma standard (http://nomisma.org/).

This field registers all the private collection(s) and/or the museum(s) that conserved the weight since it was found or acquired. To each collection can be linked a date of acquisition (format YYYY-MM-DD) and an inventory number (free text).

Required format: Drop-down list.

This field registers all the relevant bibliographical references, in an abbreviated form (usually with the author-date system). To each bibliographical reference can be linked a page or column number, a reference number, a plate or figure number, and a short comment. This short comment is mainly intended to point out some features of the bibliographical reference, such as the mention of a wrong inventory number, a mistaken identification between several weights, or the use of a specific typology.
