Code generation tools are +used to generate both server-side type-safe endpoint routes and client-side +libraries. Auto-generated reference documentation is, for now, available at +<https://api.qa.fatcat.wiki>. + +All API traffic is over HTTPS; there is no insecure HTTP endpoint, even for +read-only operations. To start, all endpoints accept and return only JSON +serialized content. + +## Editgroups + +All mutating entity operations (create, update, delete) accept an +`editgroup_id` query parameter. If the parameter isn't set, the editor's +"currently active" editgroup will be used, or a new editgroup will be created +from scratch. It's generally preferable to manually create an editgroup and use +the `id` in edit requests; the allows appropriate metadata to be set. The +"currently active" editgroup behavior may be removed in the future. + +## Sub-Entity Expansion + +To reduce the need for multiple GET queries when looking for common related +metadata, it is possible to include linked entities in responses using the +`expand` query parameter. For example, by default the `release` model only +includes an optional `container_id` field which points to a container entity. +If the `expand` parameter is set: + + https://api.qa.fatcat.wiki/v0/release/aaaaaaaaaaaaarceaaaaaaaaam?expand=container + +Then the full container model will be included under the `container` field. +Multiple expand parameters can be passed, comma-separated. + +## Authentication and Authorization + +There are two editor types: bots and humans.

This applies to the +catalog metadata itself (titles, entity relationships, citation metadata, URLs, +hashes, identifiers), as well as "meta-meta-data" provided by editors (edit +descriptions, progeny metadata, etc). + +The core catalog is designed to contain only factual information: "this work, +known by this title and with these third-party identifiers, is believed to be +represented by these files and published under such-and-such venue". As a norm, +sourcing metadata (for attribution and progeny) is retained for each edit made +to the catalog. + +A notable exception to this policy are abstracts, for which no copyright claims +or license is made. Abstract content is kept separate from core catalog +metadata; downstream users need to make their own decision regarding reuse and +distribution of this material. + +As a social norm, it is expected (and appreciated!) that downstream users of +the public API and/or bulk exports provide attribution, and even transitive +attribution (acknowledging the original source of metadata contributed to +Fatcat). As an academic norm, researchers are encouraged to cite the corpus as +a dataset (when this option becomes available). However, neither of these norms +are enforced via the copyright mechanism. + +As a strong norm, editors should expect full access to the full corpus and edit +history, including all of their contributions. + +## Immutable History + +All editors agree to the licensing terms, and understand that their full public +history of contributions is made irrevokably public. Edits and contributions +may be *reverted*, but the history (and content) of their edits are retained. +Edit history is not removed from the corpus on the request of an editor or when +an editor closes their account. + +In an emergency situation, such as non-bibliographic content getting encoded in +the corpus by bypassing normal filters (eg, base64 encoding hate crime content +or exploitive photos, as has happened to some blockchain projects), the +ecosystem may decide to collectively, in a coordinated manner, expunge specific +records from their history. + +## Documentation Licensing + +This guide ("Fatcat: The Guide") is licensed under the Creative Commons +Attribution license. + +## Software Licensing + +The Fatcat software project licensing policy is to adopt strong copyleft +licenses for server software (where the majority of software development takes +place), and permissive licenses for client library and bot framework software, +and CC-0 (public grant) licensing for declarative interface specifications +(such as SQL schemas and REST API specifications). + +## Privacy Policy + +*It is important to note that this section is currently aspirational: the +servers hosting early deployments of fatcat are largely in a default +configuration and have not been audited to ensure that these guidelines are +being followed.* + +It is a goal for fatcat to conduct as little surveillence of reader and editor +bahavior and activities as possible.
