TRiDaS 1.1: The tree-ring data standard

Tree-ring research and collaboration are currently being hampered by the lack of a suitable data-transfer standard for both data and metadata. This paper highlights the issues currently being faced and proposes a solution that, if adopted by the global dendro community, will open up the possibility of exciting new research collaborations. The solution consists of a data model for dendrochronological data and metadata, and an eXtensible Markup Language (XML) schema as a technical vehicle to exchange this data and metadata. The technology and structure of the standard enable future versions to be developed that will satisfy evolving requirements whilst remaining backwards compatible.
