DCCD Repository tips

Tips for data owners - creating TRiDaS XML and uploading to the DCCD

If you only want to upload data and metadata stored in non-TRiDaS tree-ring files (e.g., Heidelberg format), and do not wish to upload associated information such as photo's and research reports, please follow steps 1 and 5-8 described below.

If you also want to upload research reports, photo's and/or other associated files, follow steps 1-8.


  1. Use TRiCYCLE for creating TRiDaS XML from tree-ring files. When converting a single stacked file that contains all series of a single project, just run your current version of TRiCYCLE.
    If you want to convert separate files into a single TRiDaS XML project file,
    please dowload the new version developed in September 2011 by Peter Brewer for this purpose.  
    In this new version you can use the pull down menu at the bottom of the screen to tell TRiCYCLE to treat files as:
    - separate projects (as before)
    - all from one project
    - all from one object 
    TRiCYCLE will take the project/object info (depending on your selection) from the first file in the list and will discard any other project/object info contained in the remaining files.
  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 (head of the lab);
    • Period of research (the date of the research);
    • Type of material that was studied (e.g., archaeology, ship 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. Please note: data owners can alter permission levels of their projects at any time, also after a project has been archived.

  8. In the DCCD environment: archive the project.
