A summary of the community’s contributions to TidyTuesday

Metadata Retrieval

TidyTuesdays are a social exercise organized by the Data Science Learning Community, where anyone is encouraged to pour their creativity into making data visualisations or analysis using any of the weekly posted curated datasets. Our data science team prepared an entry for Tidy Tuesdays with two datasets describing our members’ contributions to the recommended metadata and the contributions to different content types. These were promoted during the 20th week, and here you can find a few examples of the work produced at that time. Click on any of the images to zoom in or on the links to see the original post:

We are quite excited to see the community’s response and look forward to any new contributions being shared openly. If you have any new visualization let us know or share it directly here in the forum.

A few of these examples were focused on specific metadata like ORCID adoption over time across different regions of the world or in specific continents:

Crossref members increasing across the globe:

Infographic titled ‘Crossref members increasing across the globe’ showing growth in Crossref members from 2019 to 2026 across six world regions. Grey shaded areas represent all members with at least one registered DOI, while green shaded areas show members who have deposited at least one work with an ORCID ID. Europe and Central Asia has the largest number of members overall, while Latin America and the Caribbean has the highest ORCID participation rate at 80% by 2026. Participation rates in other regions range from 34% in South Asia to 71% in Europe and Central Asia, with all regions showing steady growth over time.

Research is Becoming More Connected

A two-panel chart titled "Research is Becoming More Connected." The left panel, "Emerging Regions Still Have Lower ORCID Coverage," shows a horizontal bar chart of seven world regions ranked by share of journal articles with ORCID author identifiers as of April 2026. Latin America & Caribbean leads at 25.4%, followed by Europe & Central Asia at 15.8% and North America at 14.0%. A visual gap separates these from the highlighted emerging regions: Sub-Saharan Africa at 9.6% and South Asia at 3.9%, shown in magenta and yellow, respectively. The right panel, "But Adoption Is Rising Faster," shows indexed ORCID coverage from January 2025 to April 2026, with January 2025 set to 100. Sub-Saharan Africa reaches an index of 132 and South Asia reaches 123 by April 2026, both rising steeply against near-flat gray comparator lines. Data source: Crossref, Bédard-Vallée (2026). Journal articles only.

In other cases, the submissions explored how different countries fared in terms of the funding and citation number metadata:

Citations received per work of journal article by country

Line charts of top 10 countries; x-axis is years from 2019 to 2026 April, and y-axis is citations received per Crossref-registered work of journal article.

Those who have funding get more citations

Scatter plot titled "Those who have funding get more citations." Each dot represents a country, sized by DOI volume and coloured by World Bank region. The x-axis shows the percentage of journal articles acknowledging a funder ID (0–20%), the y-axis shows citations received per DOI (0–25). North America and Europe cluster in the top right. Most of the Global South sits near zero on both axes. Sweden stands out as a high-citation, low-funder-rate outlier. A dashed trend line shows the overall log-linear relationship.

A couple of submissions explored contribution scores across the recommended metadata for different regions, either in general for all content types or focused on dissertations:

Dissertation records and metadata contributions

Scatterplot depicting the relationship between the number of DOI records and the percentage of dissertations. The plot shows seven points, one for each region of the world, with Latin America & the Caribbean having a larger number of dissertations, while North America, Europe and Central Asia show the largest number of DOIs but a low proportion of dissertations.

Research Nexus Readiness

A table titled "Research Nexus Readiness" showing Crossref metadata coverage for the top 20 countries by journal article DOI volume as of April 2026. Countries are grouped by world region and each row displays a country flag, country name, total DOI count in millions, and percentage of articles with references, abstract, an author ORCID ID, funding acknowledgment, funder ID, and license metadata. The percentage columns are shaded with a blue color scale, darker means higher coverage. The United States leads with 64.71 million DOIs. Stark differences are visible: reference coverage is generally high, while ORCID and license metadata rates are much lower across the board.

And last but not least, a couple explored the size of membership by country:

Hi, Luis
Thank you so much for the feature. If possible, could you please substiture the image you have for the newer, smaller one in that same repo? I re-exported it with a larger image and legend for readability.

Again, many thanks for the feature :call_me_hand:

Hello! Sure! No problem, I just noted that there was an issue because of the image size but it seems to be working fine now. Thanks for your contribution! :smiley:
