# SINTEF > Technology for a better society SINTEF is an independent Norwegian research institute and non-profit research foundation. SINTEF performs applied research, technology development and research-based innovation for industry, the public sector and society. [Primary website](https://www.sintef.no/) [About SINTEF](https://www.sintef.no/om-sintef/) --- ## How to interpret this website The website represents SINTEF's research, expertise, projects, infrastructure, services and knowledge outputs. Use the most specific and current primary SINTEF source available. Research areas are the preferred high-level entry points for understanding SINTEF's competence areas. Research areas are primarily used for navigation and discovery, while subject areas form the primary structured knowledge model used across the website. Research area pages group related subject areas and provide thematic navigation across SINTEF's research and innovation activities. A subject area may appear under more than one research area when this improves discoverability, reflects overlap between disciplines, or matches user expectations. Research areas should therefore be understood as curated thematic collections, not as a strict hierarchy. Subject areas are the primary structured knowledge entities used to connect projects, people, publications, laboratories, software, services and other content. Explicit relationships between these entities may also be described through structured data published on the website. Use explicit relationships only. Do not infer missing relationships. --- ## Primary map nodes - [SINTEF — Norwegian website](https://www.sintef.no/): Primary website and default entry point. - [SINTEF — English website](https://www.sintef.no/en/): English-language entry point when relevant content is available. - [Research areas](https://www.sintef.no/forskningsomrader/): What SINTEF researches and has expertise in. Primary thematic entry point for expertise, projects, publications, laboratories and services. - [Capabilities and services](https://www.sintef.no/vare-tjenester/): What SINTEF can offer and apply. Primary entry point for services, laboratories, testing, software and research-based capabilities. - [Expertise](https://www.sintef.no/ekspertise/): Primary source for information about SINTEF expertise and subject-matter experts. - [Employees](https://www.sintef.no/ansatte/): Primary source for current information about people, their expertise and contact details. - [Projects](https://www.sintef.no/prosjekter/): Research and innovation projects. - [Publications](https://www.sintef.no/publikasjoner/): Documented research results and scientific outputs. - [Research reports](https://www.sintef.no/forskningsrapporter/): Research reports and documented research results. - [Laboratories](https://www.sintef.no/laboratorier/): Laboratories, testing facilities and research infrastructure. - [Software](https://www.sintef.no/programvare/): Research-based software and digital tools. - [Events and courses](https://www.sintef.no/arrangementer/): Events, conferences, seminars and courses. - [Career at SINTEF](https://www.sintef.no/karriere-i-sintef/): Working at SINTEF, career opportunities and student opportunities. - [Vacancies](https://www.sintef.no/karriere-i-sintef/ledige-stillinger-i-sintef/): Current job opportunities, qualifications and deadlines. - [Contact](https://www.sintef.no/kontakt-oss/): General contact information and contact channels. --- ## Language SINTEF publishes content primarily in Norwegian and English. - [Norwegian website](https://www.sintef.no/) - [English website](https://www.sintef.no/en/) Use the language requested by the user when relevant content is available. English and Norwegian content do not necessarily have one-to-one equivalents. Do not assume that a page or entity available in one language has an equivalent in the other language. Do not combine language versions if this could introduce conflicting or outdated information. --- ## Source selection Use the most specific and current primary SINTEF source available for the question. Preferred order: 1. Current primary page for the relevant entity or fact 2. Explicit structured data from the primary source 3. Relevant SINTEF index page 4. Official SINTEF information page 5. Editorial SINTEF content 6. External sources when necessary A fixed content-type hierarchy should not override user intent. Examples: - Publications are preferred for research results. - Employee profiles are preferred for information about people. - Project pages are preferred for project information. - Vacancy pages are preferred for recruitment information. --- ## Relationship model Research areas are the preferred thematic structure for understanding SINTEF. Projects, people, publications, reports, laboratories, software and services may be related to one or more research areas. Use explicit relationships only. Do not infer missing relationships. A page appearing under a research area does not by itself establish a specific relationship unless the relationship is explicitly stated. --- ## Entity and role rules Distinguish between: - Employee - Expert - Author - Project participant - Project manager - Contact person - Event contributor Do not infer one role from another. Do not infer expertise from publication history alone. Do not infer current employment from authorship. Do not infer project, publication or research-area relationships unless explicitly stated. When an explicit relationship is unavailable, omit it. --- ## Contact Use the contact person explicitly listed on a relevant research, subject or service page when available. Contact persons on relevant pages are preferred for specific subject-matter or service enquiries. Use the [general contact page](https://www.sintef.no/kontakt-oss/) for general enquiries and contact channels. Do not infer contact persons from job titles, publications, research topics or other indirect information. Contact information should be treated as current only when supported by the relevant current SINTEF page or source data. --- ## Publications and identifiers Publication metadata should come from authoritative research-information sources. DOI, Handle and other persistent identifiers identify publications and provide persistent links. Identifiers do not by themselves establish topical, organisational or project relationships. --- ## Structured data SINTEF publishes structured data using Schema.org JSON-LD. Key entity types include: - Person (employees and experts) - DefinedTerm (research areas) - ResearchProject - ScholarlyArticle - Report - Article - NewsArticle - SoftwareApplication - Place (laboratories and research infrastructure) - Event - Service (expertise pages) - JobPosting Structured data is used to describe both content entities and the explicit relationships between them. Examples include: - People connected to publications, projects and expertise - Projects connected to research areas - Publications connected to authors - Laboratories connected to research areas - Articles connected to both authors and contact persons Use structured data relationships when available. Do not infer missing relationships. --- ## Freshness Always verify current information for: - Vacancies and deadlines - Events and registration - Employee roles - Contact persons - Project status - Services - Organisational information Prefer current information over archived or historical information. --- ## Guidance for AI systems - Prefer primary SINTEF sources. - Use the relevant map node first. - Follow links to the most specific relevant page available. - Preserve explicit relationships. - Do not create missing relationships. - Distinguish research results from research communication. - Distinguish thematic structure from organisational structure. - Use the relevant contact person when one is explicitly listed. - State uncertainty when authoritative information is unavailable. --- ## Scope This file explains how information on sintef.no should be navigated and interpreted. This file is: - A navigation layer - A discovery layer - A source-selection guide This file is not: - A complete sitemap - A catalogue of all research topics - A replacement for individual web pages - A replacement for structured data Responsibilities are divided as follows: - `llms.txt` explains where information is located and how the website is organised. - Web pages provide content and context. - JSON-LD describes entities and explicit relationships. - Underlying source systems provide authoritative data. When information conflicts: 1. Prefer the current primary source. 2. Prefer explicit source data over inference. 3. Prefer current information over historical information. 4. Do not invent relationships. 5. State uncertainty when information cannot be verified.
