Open Access, Connections & Impact: Q&A
Can you describe what those definitions of OA mean? and where are they derived?
Dimensions relies on the Unpaywall data set to flag articles as Open Access and for the full text button. If a publication is not included there, then a full text button is not shown.
Here are the definitions of the OA categories in Dimensions.
| All OA | A free version of the publication is available (publication is either Gold, Hybrid, Bronze or Green OA) |
| Gold | Publication is published in a fully open access journal (this includes all publications with a Gold OA status in Unpaywall and those on our own fully OA list of journals) |
| Hybrid | Publication freely available under an open licence in a paid-access journal (Unpaywall OA status = Hybrid) |
| Bronze | Publication freely available on publisher’s website, but without an open licence (Unpaywall OA status = Bronze) |
| Green | Publication freely available in an OA repository (Unpaywall OA status = Green, or publication type in Dimensions = Preprint) |
| Closed | No freely available version has been identified (publication is neither Gold, Hybrid, Bronze nor Green OA) |
How will definitions of open access change with Plan S implementation?
Definitions of Open Access in Dimensions will be in line with Unpaywall’s definitions.
Can Dimensions be used with certainty to identify compliance with funder OA policies?
With respect to the content we index, yes.
How are staff affiliations to UoA groupings identified?
Dimensions does this jut the same as any other publication – The Units of Assessment is applied using title and abstract and then whomever is on the publication and gets disambiguated, then when filtering on UoAs you get the counts. This is not just limited to UK pubs or UK research outputs.
What category would you consider “diamond” OA in?
Diamond Open Access could fit in both Bronze (free to read) and Gold but we don’t have it as a standalone category.
Do you also include publishers as funders if there is a models that supports them? For example Read and Publish or Subscribe to Open?
No we don’t.
