Open data on beads, pendants, blanks from the Ceramic Age Caribbean
A database of lapidary artifacts in the Caribbean for the Ceramic Age
Recommendation: posted 28 February 2021, validated 28 February 2021
The paper 'A database of lapidary artifacts in the Caribbean for the Ceramic Age' by Queffelec et al.  presents a description of a dataset of nearly 5000 lapidary artefacts from over 100 sites. The data are dominated by beads and pendants, which are mostly made from Diorite, Turquoise, Carnelian, Amethyst, and Serpentine. The raw material data is especially valuable as many of these are not locally available on the island. This holds great potential for exchange network analysis. The data may be especially useful for investigating one of the fundamental questions of this region: whether the Cedrosan and Huecan are separate, little related developments, with different origins, or variants or a single tradition .
In addition to metric and technological details about the artefacts, the data include a variety of locational details, including coordinates, distance to coast, and altitude. This enables many opportunities for future spatial analysis and geostatistical modelling to understand human behaviours relating to ornament production, use, and discard. I recommend the authors make a minor revision to Table 1 (spatial coverage of the dataset) to make the column with the citations conform to the same citation style used in the rest of the text.
I warmly commend the authors for making transparency and reproducibility a priority when preparing their manuscript. Their use of the R Markdown format for writing reproducible, dynamic documents  is highly impressive. This is an excellent example for others in the international archaeological science community to follow. The paper is especially useful for researchers who are new to R and R Markdown because of the elegant and accessible way the authors document their research here.

This manuscript is a most welcome announcement of a database of lapidary artifacts from the Ceramic period of the Caribbean islands. Open data such as presented here is essential for the sustainability of archaeology as a discipline and a community. I recognise the authors' impressive efforts to make this manuscript transparent and reproducible by writing in R Markdown. This has enabled the reviewers to identify some specific corrections necessary before we can recommend the article. The reviewers have also made many suggestions for improving the English text to make the text easier to understand. I request that the authors study the reviews and make all of the revisions requested (the reviewers often spot the same things, so this will not be a big task). Please also look into the suggestions to improve the text and make those changes (especially those made by Bischoff on the PDF he attached to his review). I believe that once these revisions are complete, we can recommend the article to the scholarly community.
