2019 Review

This is a new entry taken from the open submission process in 2019.  It is grouped with Museum data sets as archaeological archives typically make their way to museums, but it is also closely aligned to research data.

Additional Jury Comments

There are trusted custodians of this data such as ADS, DANS or the British Museum as well as in oceanographic research agencies, but perhaps hard to integrate good practice at an international scale. The real challenge therefore is in identifying and sustaining a custodian as other bodies have experience with this data. The proliferation of innovative data recording technologies also implies likely problems of format dependence and documentation.
