There are two approaches to archiving timber groups and average chronologies in the DCCD repository, both of which differ in terms of labour and cost.

  • The TRiDaS data model allows digital linkage of individual measurement series (field: measurementSeries) to average chronologies (field: derivedSeries). For the present study this level of data accuracy requires that a new project is uploaded to the DCCD containing all series underlying the German-Rhineland chronology, as well as the chronology itself. This approach can be labour intensive since it requires that all relevant TRiDaS fields are administrated from Project down to measurementSeries level.
  • A faster, digitally less accurate method is to limit the use of TRiDaS to the Project and Object levels. Files containing references to relevant DCCD projects and measurementSeries, and containing research results such as the description and annual values of an average chronology, should be specified in the ‘files’ form in one of these levels. This approach requires discipline since revised interpretations of e.g. wood provenance should be added to the original project files stored in the DCCD.

Because the series used in this case study already had been archived in the DCCD we chose the second approach. In TRiDaBASE we created a new project (P:2015503), added the Object level, and described the research and associated files in the Project and Object comment fields. The associated files were administrated in the ‘files’ form of the Object level. This ensures that the DCCD user interface recognises these files and during uploading of the XML will require that these files are uploaded as well. The access level of the project was set at ‘Value (download)’[1]. For other Early-medieval data stored in the DCCD some adaptations of the geographical interpretations (stored in measurementSeries level under ‘Interpretation’) are forthcoming.
