 Dutch novel about dendrochronology: De Messias

​Author: Julian Winter

Publishing house: Prometheus/Bert Bakker, Amsterdam (NL)

De Messias_Book cover.jpg
In September 2015 a Dutch novel will appear in which dendrochronology plays a key role. De Messias ('The Messiah') tells the story of Emma Faber, a dendroclimatologist who becomes involved in the research of stringed instruments. Her adventures in a realm dominated by greed and vanity are intertwined with the history of Antonio Stradivari and his legacy, taking us from 17th-century Italy through Napoleonic France to post-war Berlin.

More information: see the summer catalogue of Prometheus/Bert Bakker (2015; in Dutch). For the English translation please follow this link.

 Three Roman ships from Utrecht (NL) were built in Flanders (BE)

​Link: Jansma, Haneca & Kosian 2014.

Dendrochronological research shows that Roman river barges 'De Meern 1' and 'De Meern 4', and the Roman punt 'De Meern 6', were built in north-western Flanders (Belgium). The location of the wreck sites in Utrecht-De Meern in the central Netherlands points at inland navigation between Gallia Belgica and the limes of Germania inferior.

 TRiCYCLE released

We'd like to bring your attention to a new, freely available, universal dendro data conversion tool - TRiCYCLE. Downloads for Windows, Mac and Linux are now available from:

TRiCYCLE supports conversion of data between the following formats: Belfast Apple; Belfast Archive; Besancon; CATRAS; CSV; Corina Legacy; Excel; Heidelberg; Nottingham; PAST4; Sheffield; Topham; TRiDaS; TRIMS; Tucson; Tucson Compact; VFormat; and WinDENDRO.

TRiCYCLE is designed to intelligently interpret both the data and the metadata from files. For instance information about pith, bark, species, location, measuring units etc are all read from files where available. It includes a comprehensive system for providing feedback to the end user about errors encountered or assumptions made during the conversion process.

This new open source tool has been made possible using the capabilities of the Tree-Ring Data Standard (TRiDaS) to comprehensively describe dendro data and metadata. Although we hope that TRiCYCLE will be useful in allowing collaboration between labs using different data formats, our ultimate goal is that it will help the community to adopt TRiDaS as the dendro data standard. An article containing a complete description of the tool is currently under review and will hopefully be published later this year.

We thank the many people that have helped test earlier beta versions, but please keep us informed of any bugs you come across as TRiCYCLE will continue to be developed. Keep in mind that the majority of these legacy data formats are completely undocumented. It is therefore possible that there are nuances and features present in some unusual files that have not yet been seen by the developers.

 Completing stand-alone data-conversion library
We are completing the development of a stand-alone data-conversion library that will allow conversion to and from many tree-ring data formats, including the newly developed TRiDAS format which allows for lots of metadata, as well as older formats such as Tucson, Heidelberg, TSAP, D-format, V-format, Besancon and Catras. 
DCCD-participants who want to suggest a name for this utility are invited to contact the DCCD-project leader, Prof.dr. Jansma. See the DCCD-project workspace for details.
In a few weeks the conversion library will be made available through this website. The development was funded by NWO section Humanities as part of the DCCD-project (Medium Investment subsidy).
