Dissemin API

Dissemin provides an API to query the availability of arbitrary papers. Please do not assume the interface will not change in the future as it is still being improved.

Querying by DOI

You can retrieve Dissemin’s metadata for a specific paper by DOI:

https://dissem.in/api/10.1016/j.paid.2009.02.013.

Querying by Dissemin paper ID

Dissemin stores internal numeric identifiers for its papers. These identifiers are exposed in the URLs of the paper pages, for instance. It is possible to retrieve metadata from these identifiers:

https://dissem.in/api/p/6859902

Querying by metadata fields

When the DOI or the Dissemin ID are not known, it is possible to retrieve a paper by title, authors and publication date. This is done by posting a JSON object encoding this metadata to https://dissem.in/api/query, as follows:

curl -H "Content-Type: application/json" -d '{"title":"Refining the Conceptualization of an Important Future-Oriented Self-Regulatory Behavior: Proactive Coping", "date":"2009-07-01","authors":[{"first":"Stephanie Jean","last":"Sohl"},{"first":"Anne","last":"Moyer"}]}' https://dissem.in/api/query

The date field can contain coarser dates such as 2009-07 or 2009, and authors can also be specified as plain text with {"plain":"Anne Moyer"} instead of {"first":"Anne","last":"Moyer"}.

This API method uses the internal paper deduplication strategy in Dissemin to match the bibliographic reference to a known paper in the database. This deduplication is done by computing a unique key (called fingerprint) from the title, authors and publication date. Therefore, this API method will always return at most one paper, unlike the search endpoint below which works like traditional search engines.

Searching for papers

The search interface is also exposed as an API. The parameters it understands are the same as the human-readable version at https://dissem.in/search. Statistics about the results are also returned.

two of the proactive competencies, use of resources and realistic goal
setting, and the remaining variance in well-being was explained by the

Most fields are self-explanatory, here is a quick description of the other ones:

  • classification is the code for the self-archiving policy of the publisher “OA” (available from the publisher), “OK” (some version can be shared), “UNK” (unknown/unclear sharing policy), “NOK” (restrictive sharing policy).
  • splash_url is a URL where Dissemin thinks that the paper is described, without being necessarily available. This can be a publisher webpage (with the article available behind a paywall), a page about the paper without a copy of the full text (e.g., a HAL page like https://hal.archives-ouvertes.fr/hal-01664049), or a page from which the paper was discovered (e.g., the profile of a user on ORCID).
  • pdf_url is a URL where Dissemin thinks the full text can be accessed for free. This is rarely a direct link to an actual PDF file, i.e., it is often a link to a landing page (e.g., https://arxiv.org/abs/1708.00363). It is set to null if we could not find a free source for this paper.
  • records gives a list of the places where the full text has been made available (so: repositories, homepages or social networks). Sometimes, these repositories only contain a bibliographical record and not the full text. The pdf_url field of each record indicates our assessment of the availability of that record. If the publisher has been found in RoMEO, it also indicates the summary of its policy, using the codes drawn from the RoMEO API. This list will remain empty if no DOI is provided.
