After serving our community and improving our platform for over ten years, we have made the calculated decision to adjust our rates. The improved services provided include: the per-file cap has been raised from 10 MB to 50 MB per file, and now digital curators will be available to assist uploaders with a quality assurance and control routine for their materials.

As a result, the adjusted prices are:

$20 per 1-99 files

$10 per 100-499 files

>500 files Email tDAR 

Please contact if you have any questions or need assistance.

These changes will go into effect in October 2023

Sébastien Plutniak research stay at the Center for Digital Antiquity / SHESC (May 1st–June 30th)

Screen capture of archeoViz homepage

Sébastien Plutniak is researcher at the French National Center for Scientific Research (CNRS) and currently works at the CITERES laboratory, in Tours. His background is sociology and history of science (PhD) and archaeology (MA), with a strong flavor of computational methods. He will stay at the Center for Digital Antiquity from May 1st to June 30th, funded by the European SEADDA COST Action (Saving European Archaeology from the Digital Dark Age) – of which the CDA is a partner.

Sébastien will work on his “archeoViz” project, a web application to visualize, interactively explore, and quickly and seamlessly deploy and communicate spatialized archaeological data at site’s scale. 

Distributed as an R package, archeoViz can be used locally on a personal computer or deployed on a server. It can be run statically with a specific dataset or dynamically by loading data through its interface. Static instances of archeoViz are indexed on the archeoViz portal. During his stay, Sébastien will learn from the tDAR team’s experience, develop methods to connect tDAR and archeoViz, and set up visualizations of tDAR datasets.

Besides his interest in archaeological data representation and processing, Sébastien’s other lines of investigation deal with archaeology on Islands throughout Southeast Asia, the history and theory of formal approaches in the humanities and the social sciences, the history of prehistoric archaeology in Western Europe, the philosophy of the social sciences (epistemology and ontology, including archaeology).

During these two months, he will be more than happy to exchange with anyone at SHESC interested in these questions, and beyond!

Data management is a topic constantly on our minds here at the Center for Digital Antiquity (DA). Exploring topics such as appropriate file formats, sufficient metadata, and proper digitization practices, the staff at DA strive to provide support with workshops and consultation. Thus, in hopes of answering some of the most common questions, over the past year we have created new help documentation and videos tutorials that are now available under our Using tDAR page.

Data Management Survey

While creating this new documentation, we found that we are not alone in thinking about how archaeologists handle data. A recent survey from the ARIADNEplus project consortium on data management practices has recently crossed our desks and we hope others are able to contribute to this project.

To take part in this survey please see the description and survey link below:

The ARIADNEplus project has launched a survey on data management policies of archaeological repositories.

The survey focuses on the current policies concerning access to and re-use of archaeological data to contribute to the application of the FAIR principles in the field. Target groups are managers, curators and IT units of digital archaeological repositories and collections, both in operation or currently being prepared.

Survey link:

The survey is managed by the Central Institute for the Union Catalogue (ICCU) of the Italian Ministry of Culture on behalf of the ARIADNEplus project consortium.

For any questions related to the survey please contact Flavia Massara:

We look forward to seeing the results of this survey and are open to hearing any suggestions from our users on how best we can help you manage your archaeological data. We hope to continue adding new video tutorials and would appreciate any feedback or suggestions! For any questions or suggestions, please drop us a note at

Last week, our Senior Digital Data Curator, Rachel Fernandez, was out on the road again to present at the 2019 Air Force Cultural Resource Workshop, held at the Kirtland Air Force Base in Albuquerque, New Mexico. Sponsored by the Air Force Civil Engineer Center (AFCEC), the three-day workshop included natural and cultural resource managers from Air Force installations spread across the states to discuss issues and developments in cultural resource management within the Air Force.

One of the ongoing projects discussed at the meetings was the Center for Digital Antiquity and AFCEC’s collaboration to preserve Air Force cultural resources within tDAR. At present, there are over 500 active resources within tDAR from over 17 different installations, with another 2500 resources in different stages of completion. At this meeting, Rachel was able to provide training on the tDAR system and answer questions concerning organizing and managing digital resources.

We hope to continue being involved in these workshops and work closely with AFCEC to provide digital curation and preservation services for the US Air Force.

To learn more about the US Air Force CRM Program and the challenges of digital data curation, read our Reports in Digital Archaeology Number 4, The US Air Force CRM Program Meets the Challenges of Digital Data Curation: A Case Study Using tDAR

The ARIADNEplus project invites archaeological researchers and data managers to participate in an online survey on community needs regarding data sharing and access, new services and tools, and related training needs.

ARIADNEplus, is a project funded by the European Commission under the Horizon 2020 Programme. It aims to integrate archaeological datasets in a digital infrastructure so that researchers can use them with services and tools which will also be provided by the project.

We kindly invite you to share your experience and your views on the survey topics. Please note that the survey includes matrix table questions, therefore using a desktop or notebook (not a tablet or mobile) is recommended.

Workshop Dates: November 19- 23, 2018

Location: University of Ghana, Department of Archaeology and Heritage Studies

Participants: University of Ghana, Dept. of Archaeology and Heritage Studies Faculty and Students, Ghana Museum and Monuments Board Staff, University of Ghana, Institute of African Studies

Workshop Instructors: Ann Stahl, University of Victoria, Dept. of Anthropology, Lisa Goddard, University of Victoria Libraries, Rachel Fernandez, Center for Digital Antiquity

Recently, our Senior Digital Curator, Rachel Fernandez, along with Ann Stahl and Lisa Goddard from the University of Victoria, had the opportunity to lead a week-long workshop at the University of Ghana in Accra. This workshop is part of a larger Social Sciences and Humanities Research Council (SSHRC) of Canada Partnership Development grant titled, “Improving African Future Using Lessons from the Past” (IAfF). Partners on this grant include the University of Victoria, the University of Ghana, Ghana Museums and Monuments Board, Center for Digital Antiquity, and the Banda Traditional Council. The grant focuses on creating digital heritage collections that are not only relevant to scholars but to local communities and the broader public, with the idea of fostering digital heritage “communities of practice.”

At the kickoff workshop for the grant, a great group of 30 students, faculty, and staff participated in a series of lectures and hands-on activities throughout the week that touched upon topics such as best practices for digital data management and converting slides into digitized files.

By the end of the intensive week, the group had the chance to digitize documents, sort and digitize color slides, take photos and videos with audio, organize documents and add important metadata, and lastly, make draft digital data management plans to help them organize their own projects.  

Rachel was able to not only talk about the curation and planning activities that the Center for Digital Antiquity is able to provide, but also learned  about the challenges and innovative projects that are happening in Ghana. This partnership and workshop is a great example of how the archaeological community can come together with broader local and national communities to provide greater accessibility and increase preservation of valuable cultural heritage resources. We look forward to continuing working on this project and assisting in the workshops to come.
