ELISA

ELISA (Enabling Linux in Safety Applications) is a Linux Foundation collaborative project that builds the shared tools, processes and evidence needed to use Linux in safety-critical systems. Its working groups and special interest groups span automotive, aerospace, medical devices, railways, space-grade Linux and open-source engineering process, producing white papers, case studies, kernel analysis tooling and a public technical directory. ELISA develops two tools of its own: BASIL, a software quality management and traceability application with an HTTP REST API and SPDX 3.0.1 export, and ks-nav, kernel-source navigation tooling. ELISA itself publishes a machine-readable API surface at https://elisa.tech/wp-json/ — declared through an RFC 9727 api-catalog and described by a live OpenAPI 3.0.0 document — plus an llms.txt and permissive Content Signals for AI use.

ELISA publishes 6 APIs on the APIs.io network, including Categories API, Doc API, Events API, and 3 more. Tagged areas include Embedded, Linux, Linux Foundation, Safety, and Functional Safety.

ELISA’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, pricing, and 28 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/elisa: open an issue to ask a question, or submit a pull request to add artifacts.

  description: BASIL — "The FuSa Spice" — is ELISA's own software quality management tool. It decomposes a software component
    specification into snippets, maps work items (software requirements, test specifications, test cases, test runs, justifications,
    documents) onto them, tracks completeness and exports a traceability matrix as SPDX Model 3, HTML or PDF. It ships a Flask
    HTTP REST API specifically so it can be driven from automated toolchains, and it is self-hosted — operators build the
    API and app containers from the provided Containerfiles. No OpenAPI or other machine-readable contract is published for
    it.
