These are - integers prefixed with "Q", like "Q4321". Each `release` entity can be - associated with at most one Wikidata entity (this field is not an array), and - Wikidata entities should be associated with at most a single `release`.

This is a free-form string, and could - represent the first page, a range of pages, or even prefix pages (like - "xii-xxx"). -- `publisher` (string): name of the publishing entity. This does not need to be - populated if the associated `container` entity has the publisher field set, - though it is acceptable to duplicate, as the publishing entity of a container - may differ over time. Should be set for singleton releases, like books. -- `language` (string, slug): the primary language used in this particular release of - the work. Only a single language can be specified; additional languages can - be stored in "extra" metadata (TODO: which field?). This field should be a - valid RFC1766/ISO639 language code (two letters). AKA, a controlled - vocabulary, not a free-form name of the language. -- `license_slug` (string, slug): the license of this release. Usually a - creative commons short code (eg, `CC-BY`), though a small number of other - short names for publisher-specific licenses are included (TODO: list these). -- `contribs` (array of objects): an array of authorship and other `creator` contributions to this - release. Contribution fields include: - - `index` (integer, optional): the (zero-indexed) order of this - author. Authorship order has significance in many fields. Non-author - contributions (illustration, translation, editorship) may or may not be - ordered, depending on context, but index numbers should be unique per - release (aka, there should not be "first author" and "first translator") - - `creator_id` (identifier): if known, a reference to a specific `creator` - - `raw_name` (string): the name of the contributor, as attributed in the - text of this work. If the `creator_id` is linked, this may be different - from the `display_name`; if a creator is not linked, this field is - particularly important. Syntax and name order is not specified, but most - often will be "display order", not index/alphabetical (in Western - tradition, surname followed by given name). - - `role` (string, of a set): the type of contribution, from a controlled - vocabulary. TODO: vocabulary needs review. - - `extra` (string): additional context can go here. For example, author - affiliation, "this is the corresponding author", etc. -- `refs` (array of ident strings): references (aka, citations) to other releases. References - can only be linked to a specific target release (not a work), though it may - be ambiguous which release of a work is being referenced if the citation is - not specific enough. Reference fields include: - - `index` (integer, optional): reference lists and bibliographies almost - always have an implicit order. Zero-indexed. Note that this is distinct - from the `key` field. - - `target_release_id` (fatcat identifier): if known, and the release - exists, a cross-reference to the Fatcat entity - - `extra` (JSON, optional): additional citation format metadata can be - stored here, particularly if the citation schema does not align. Common - fields might be "volume", "authors", "issue", "publisher", "url", and - external identifiers ("doi", "isbn13"). - - `key` (string): works often reference works with a short slug or index - number, which can be captured here. For example, "[BROWN2017]". Keys - generally supersede the `index` field, though both can/should be - supplied. - - `year` (integer): year of publication of the cited release. - - `container_title` (string): if applicable, the name of the container of - the release being cited, as written in the citation (usually an - abbreviation). - - `title` (string): the title of the work/release being cited, as written. - - `locator` (string): a more specific reference into the work/release being - cited, for example the page number(s). For web reference, store the URL - in "extra", not here. -- `abstracts` (array of objects): see below - - `sha1` (string, hex, required): reference to the abstract content (string). - Example: "3f242a192acc258bdfdb151943419437f440c313" - - `content` (string): The abstract raw content itself. Example: `<jats:p>Some - abstract thing goes here</jats:p>` - - `mimetype` (string): not formally required, but should effectively always get - set. `text/plain` if the abstract doesn't have a structured format - - `lang` (string, controlled set): the human language this abstract is in. See - the `lang` field of release for format and vocabulary. - -[arxiv.org]: https://arxiv.org - -#### `extra` Fields - -- `crossref` (object), for extra crossref-specific metadata - - `subject` (array of strings) for subject/category of content - - `type` (string) raw/original Crossref type - - `alternative-id` (array of strings) - - `archive` (array of strings), indicating preservation services deposited - - `funder` (object/dictionary) -- `aliases` (array of strings) for additional titles this release might be - known by -- `container_name` (string) if not matched to a container entity -- `subtitle` (string) -- `group-title` (string) for releases within an collection/group -- `translation_of` (release identifier) if this release is a translation of - another (usually under the same work) -- `withdrawn_date` (string, ISO date format): if this release has been - retracted (post-publication) or withdrawn (pre- or post-publication), this is - the datetime of that event. Retractions also result in a `retraction` release - under the same `work` entity. This is intended to migrate from "extra" to a - full release entity field. - -#### `release_type` Vocabulary - -This vocabulary is based on the -[CSL types](http://docs.citationstyles.org/en/stable/specification.html#appendix-iii-types), -with a small number of (proposed) extensions: - -- `article-magazine` -- `article-journal`, including pre-prints and working papers -- `book` -- `chapter` is allowed as they are frequently referenced and read independent - of the entire book. The data model does not currently support linking a - subset of a release to an entity representing the entire release. The - release/work/file distinctions should not be used to group multiple chapters under - a single work; a book chapter can be it's own work. A paper which is - republished as a chapter (eg, in a collection, or "edited" book) can have - both releases under one work. The criteria of whether to "split" a book and - have release entities for each chapter is whether the chapter has been - cited/reference as such. -- `dataset` -- `entry`, which can be used for generic web resources like question/answer - site entries. -- `entry-encyclopedia` -- `manuscript` -- `paper-conference` -- `patent` -- `post-weblog` for blog entries -- `report` -- `review`, for things like book reviews, not the "literature review" form of - `article-journal`, nor peer reviews (see `peer_review`) -- `speech` can be used for eg, slides and recorded conference presentations - themselves, as distinct from `paper-conference` -- `thesis` -- `webpage` -- `peer_review` (fatcat extension) -- `software` (fatcat extension) -- `standard` (fatcat extension), for technical standards like RFCs -- `abstract` (fatcat extension), for releases that are only an abstract of a - larger work. In particular, translations. Many are granted DOIs. -- `editorial` (custom extension) for columns, "in this issue", and other - content published along peer-reviewed content in journals. Many are granted DOIs. -- `letter` for "letters to the editor", "authors respond", and - sub-article-length published content. Many are granted DOIs. -- `stub` (fatcat extension) for releases which have notable external - identifiers, and thus are included "for completeness", but don't seem to - represent a "full work". - -An example of a `stub` might be a paper that gets an extra DOI by accident; the -primary DOI should be a full release, and the accidental DOI can be a `stub` -release under the same work. `stub` releases shouldn't be considered full -releases when counting or aggregating (though if technically difficult this may -not always be implemented). Other things that can be categorized as stubs -(which seem to often end up mis-categorized as full articles in bibliographic -databases): - -- commercial advertisements -- "trap" or "honey pot" works, which are fakes included in databases to - detect re-publishing without attribution -- "This page is intentionally blank" -- "About the author", "About the editors", "About the cover" -- "Acknowledgments" -- "Notices" - -All other CSL types are also allowed, though they are mostly out of scope: - -- `article` (generic; should usually be some other type) -- `article-newspaper` -- `bill` -- `broadcast` -- `entry-dictionary` -- `figure` -- `graphic` -- `interview` -- `legislation` -- `legal_case` -- `map` -- `motion_picture` -- `musical_score` -- `pamphlet` -- `personal_communication` -- `post` -- `review-book` -- `song` -- `treaty` - -For the purpose of statistics, the following release types are considered -"papers": - -- `article-journal` -- `chapter` -- `paper-conference` -- `thesis` - -#### `release_status` Vocabulary - -These roughly follow the [DRIVER](http://web.archive.org/web/20091109125137/http://www2.lse.ac.uk/library/versions/VERSIONS_Toolkit_v1_final.pdf) publication version guidelines, with the addition of a `retracted` status. - -- `draft` is an early version of a work which is not considered for peer - review. Sometimes these are posted to websites or repositories for early - comments and feedback. -- `submitted` is the version that was submitted for publication. Also known as - "pre-print", "pre-review", "under review". Note that this doesn't imply that - the work was every actually submitted, reviewed, or accepted for publication, - just that this is the version that "would be". Most versions in pre-print - repositories are likely to have this status. -- `accepted` is a version that has undergone peer review and accepted for - published, but has not gone through any publisher copy editing or - re-formatting. Also known as "post-print", "author's manuscript", - "publisher's proof". -- `published` is the version that the publisher distributes. May include minor - (gramatical, typographical, broken link, aesthetic) corrections. Also known - as "version of record", "final publication version", "archival copy". -- `updated`: post-publication significant updates (considered a separate release - in Fatcat).

This is a free-form string, and could + represent the first page, a range of pages, or even prefix pages (like + "xii-xxx"). +- `publisher` (string): name of the publishing entity. This does not need to be + populated if the associated `container` entity has the publisher field set, + though it is acceptable to duplicate, as the publishing entity of a container + may differ over time. Should be set for singleton releases, like books. +- `language` (string, slug): the primary language used in this particular release of + the work.

ISBN-9 and other formats + should be converted to canonical ISBN-13. +- `pmid` (string): external identifier for PubMed database. These are bare + integers, but stored in a string format. +- `pmcid` (string): external identifier for PubMed Central database. These are + integers prefixed with "PMC" (upper case), like "PMC4321".

Retractions also result in a `retraction` release + under the same `work` entity. This is intended to migrate from "extra" to a + full release entity field. + +#### `release_type` Vocabulary + +This vocabulary is based on the +[CSL types](http://docs.citationstyles.org/en/stable/specification.html#appendix-iii-types), +with a small number of (proposed) extensions: + +- `article-magazine` +- `article-journal`, including pre-prints and working papers +- `book` +- `chapter` is allowed as they are frequently referenced and read independent + of the entire book. The data model does not currently support linking a + subset of a release to an entity representing the entire release. The + release/work/file distinctions should not be used to group multiple chapters under + a single work; a book chapter can be it's own work. A paper which is + republished as a chapter (eg, in a collection, or "edited" book) can have + both releases under one work. The criteria of whether to "split" a book and + have release entities for each chapter is whether the chapter has been + cited/reference as such. +- `dataset` +- `entry`, which can be used for generic web resources like question/answer + site entries. +- `entry-encyclopedia` +- `manuscript` +- `paper-conference` +- `patent` +- `post-weblog` for blog entries +- `report` +- `review`, for things like book reviews, not the "literature review" form of + `article-journal`, nor peer reviews (see `peer_review`) +- `speech` can be used for eg, slides and recorded conference presentations + themselves, as distinct from `paper-conference` +- `thesis` +- `webpage` +- `peer_review` (fatcat extension) +- `software` (fatcat extension) +- `standard` (fatcat extension), for technical standards like RFCs +- `abstract` (fatcat extension), for releases that are only an abstract of a + larger work. In particular, translations. Many are granted DOIs. +- `editorial` (custom extension) for columns, "in this issue", and other + content published along peer-reviewed content in journals. Many are granted DOIs. +- `letter` for "letters to the editor", "authors respond", and + sub-article-length published content. Many are granted DOIs. +- `stub` (fatcat extension) for releases which have notable external + identifiers, and thus are included "for completeness", but don't seem to + represent a "full work". + +An example of a `stub` might be a paper that gets an extra DOI by accident; the +primary DOI should be a full release, and the accidental DOI can be a `stub` +release under the same work. `stub` releases shouldn't be considered full +releases when counting or aggregating (though if technically difficult this may +not always be implemented).
