Digital Collaboratory for Cultural Dendrochronology (DCCD)
A digital data library for dendrochronology

Tips for DCCD users


A. Creating TRiDaS XML metadata 


Many users of the DCCD have been using old-legacy tree-ring data formats for storing metadata of wood samples (tree species, number of tree rings in the series, dendrochronological date et cetera). In this case a useful approach towards producing TRiDaS XML is to:


1.      use TRiCYCLE for creating TRiDaS XML from tree-ring files (in case of trouble, questions etc, please contact the developers of TRiCYCLE);


2.      import the resulting file into TRiDaBASE version 1.1;


3.      use TRiDaBASE to add references to your tree-ring files and other associated files. This way the DCCD will know which tree-ring files and other files it has to upload together with the TRiDaS XML. Click here to learn how to add references to tree-ring series.


4.      use TRiDaBASE to produce TRiDaS XML;


5.      upload the TRiDaS XML to the DCCD, where if will become a draft project;


6.      in the DCCD environment: edit your draft project so that it includes all info you wish to store. Please note: in the edit mode of the DCCD you can only change descriptive and interpretative metadata. It is not possible to add extra associated files such as ring-width series and photo’s. If you are missing associated files in your uploaded project, please erase this project (this can be done in draft status), add references to missing associated files in TRiDaBASE, and continue with step 4).


7.      in the DCCD environment: set the permission levels to this project. The default level is ‘Maximum security’ and will only show some fields to other users. These public fields are:

·         Project title (the human-readable title under which a project is stored);

·         Project type (e.g., dating; anthropology; forest dynamics, ecology, pyrochronology, climatology);

·         Principal investigator (the scientist responsible for the project’s content);

·         Period of research (the date of the research);

·         Type of material that was studied (e.g., archaeology, ships's archaeology, standing building, wood carving, musical instrument, living tree);

·         Laboratory (name of the laboratory that produced the data);

·         Object title: the human-readable title given to the studied object(s) in the file.

The data owner can set other (‘deeper’) default permission levels. In addition the data owner can set deviating permission levels for specific individual DCCD members.


8.      in the DCCD environment: archive the project.
