A journal that publishes only in open access.
We follow Unpaywall’s approach on defining fully Open Access journals and publishers and we construct the lists of the latter using Unpaywall data.
In brief, a journal is fully Open Access if one or more of the following occur:
- It is in the Directory of Open Access Journals (DOAJ)
- It has a known fully OA Publisher (curated list).
- It only publishes OA articles.
A fully OA journal that does not charge article processing charges (APCs).
We obtain APC data from DOAJ using DOAJ’s Public Data Dump (an exportable version of the journal metadata). We used it to determine whether a particular fully OA journal charges APCs.
A journal that charges for access to its articles.
Journals without any open access articles.
A subscription journal where some of its articles are open access.
Journals with open access articles that are not fully OA journals.
"A Transformative Journal is a subscription/hybrid journal that is actively committed to transitioning to a fully Open Access journal.
In addition, a Transformative Journal must:
- gradually increase the share of Open Access content; and
- offset subscription income from payments for publishing services (to avoid double payments)."

We identify Transformative Journals by ISSN matching with the publicly available Transformative Journals data from Plan S initiative.
Transformative agreements are those contracts negotiated between institutions (libraries, national and regional consortia) and publishers that transform the business model underlying scholarly journal publishing, moving from one based on toll access (subscription) to one in which publishers are remunerated a fair price for their open access publishing services.

We have identified and retrieved from OpenAPC the set of articles with metadata published under transformative agreements for Ireland.
Green articles are published in toll-access journals, but archived in an OA archive, or "repository". These repositories may be discipline-specific (like ArXiv) or institutional repositories operated by universities or other institutions. Green articles may be published versions or preprints, and must be accompanied by a specified licence that outlines how the material can be used, shared, and distributed.
We follow the Budapest Open Access Initiative definition.
An open access scientific publication published in a hybrid journal with an open license. Hybrid articles are free to read at the time of publication, with an open license. These are usually published in exchange for an article processing charge (APC).
We define hybrid journals above.
Gold articles have all the same characteristics as Hybrid articles, but are published in all-Open Access journals, which are in turn called "Gold journals", or just "OA journals".
We define all-Open Access journals as OA (Gold) journals above.
Bronze articles are free to read on the publisher's website, without a licence that grants any other rights. There may be a delay between publication and availability to read, and often articles can be removed unilaterally by the publisher.
As in definition
Green articles deposited in a repository without any particular licence specified.
As in definition
A peer reviewed publication is a scholarly article that has been evaluated and critiqued by independent experts in the same field before being published. This method is widely used by academic journals to enhance the credibility and reliability of published research.
A publication is peer-reviewed if either of the following criteria is true.
- Curated Peer-Review Assessment: The OpenAIRE team has engaged in a curation process to determine peer-review status. This hand-curated assessment has been integrated into the Graph and is continuously under development.
- Exclusion of Grey Literature: We filter out grey literature, which includes document types that typically bypass the peer review process, such as reports, and white papers. Given that the OpenAIRE Graph aggregates data from various sources, resulting in merged records, we specifically exclude entries where all instances are identified as grey literature.

Presence of DOI from Crossref: Since Crossref predominantly catalogues peer-reviewed content, its DOIs help maintain the scholarly credibility of our included publications.
Publicly funded refers to research activities supported wholly or partially by public funds, such as grants, salaries, or contracts.
This filter has been specifically curated for Ireland.
We used the responses for the publicly funded RPOs/RFOs from the National Open Access Monitor Survey conducted by IReL. We also utilised OFR’s metadata to identify publicly funded RFOs with the “Government” type. OFR’s metadata offers pertinent information on funder type which is being integrated in the Graph.
The number of downloads of a publication’s full text in a specific time frame, from a given set of data sources.
We utilize the usage data for the downloads from OpenAIRE’s Usage Counts service that harvests it from a set of datasources. The time range of available downloads varies for each datasource.
The number of citations received by a publication. A citation is a reference to the source of information used in a publication.
We utilize the number of citations of a publication from the calculated impact indicators, provided by BIP!. Precisely, we use the Citation Count (CC) impact indicator, which sums all citations received by each article.

Reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network.
Reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
Reflects the initial momentum of an article directly after its publication, based on the underlying citation network.
