To be complete
Osmetheca has a simple ambition: to cover niche perfumery in its full extent, and to answer with precision every question a curious reader can raise on the subject. A living encyclopedia of raw materials and olfactive families. A technical glossary without equivalent in English. Serious portraits of creator perfumers and independent houses. Dense, structured entries on individual perfumes. Pedagogical guides for those just starting. A subjective journal for readers already deep into the passion. A rigorous FAQ for concrete questions.
When you look for a precise answer to a simple question on oud, Taif rose, the British perfumery or the olfactive signature of an independent house, you want to consult a single source that is dense, structured and verified. That source is what Osmetheca proposes.
The project aims at a consultation that is both fluid for the curious reader and precise for the seasoned amateur, with the same depth of information across every entry of the site.
Six writing principles
Six principles shape the writing of every entry on the site.
Factual density
Each entry proposes information that is dense, organized and verifiable. Concision is never the enemy of precision.
Explicit sources
Each factual statement points to an authority source, named in the text. Nothing is asserted without backing.
Terminological consistency
Vocabulary stays constant across the site. Glossary definitions hold for the Encyclopedia, the Perfume entries, the Guides and the FAQ.
Descriptive and subjective kept apart
Descriptive entries aim at objectivity (Encyclopedia, Glossary, Perfumers, Houses, Perfumes, FAQ). Guides assume pedagogy. The Journal owns a subjective voice.
Documentary honesty
No invented date, no fanciful perfumer, no fabricated classification. When a piece of information cannot be verified, it stays out of the entry or appears clearly marked as a hypothesis.
Entries that complete each other
Osmetheca entries complete each other. A Perfume entry links to its house, its perfumer, its olfactive family and its raw materials. Understanding is built through cross-reading.
Where the information comes from
Osmetheca's factchecking relies on sources hierarchized by decreasing authority for each type of statement.
French institutional sources
- Société Française des Parfumeurs (SFP): official olfactive classification, biographies of creator perfumers, François Coty prize
- ISIPCA Versailles: pedagogical reference of perfumery training, biographies of perfumers trained there
- Osmothèque de Versailles: the world conservatory of perfume, historic reconstructions, pre-IFRA original formulas
International regulatory and industrial sources
- IFRA (International Fragrance Association): restriction Standards for raw materials, allergens
- RIFM (Research Institute for Fragrance Materials): perfumery toxicology
- ECHA (European Chemicals Agency): REACH regulation, SVHC classifications
- CITES: international trade of endangered raw materials (oud, rosewood, Brazilian rosewood, Tonkin musk)
- Industry players: Givaudan, Firmenich, IFF, Symrise, Mane, Robertet, Takasago (captives, research, publications)
Critical and community sources
- Official house websites, top priority for founding dates, founder biographies, perfumer lineages
- International expert blogs: Bois de Jasmin, Now Smell This, Persolaise, Çafleurebon, The Perfume Magpie
- Community databases: Fragrantica, Basenotes, Parfumo (consulted with critical distance for compositions, never as a single source)
No statement without a source. Rigor is not negotiable. ”
Systematic factchecking
Before publication, each entry passes through a careful audit on every verifiable statement. We check house founding dates, the names of creator perfumers, perfume launch years, olfactive classifications, IFRA restrictions in force, CITES statuses, and anything that can be confronted with a source.
Three error levels are distinguished. Critical errors (incorrect date, wrong perfumer attribution, false olfactive classification) are not tolerated. Intermediate errors (approximate dated price, unconfirmed secondary source) stay under 5 percent. Minor errors (debatable interpretive nuance) stay under 10 percent.
Verification runs section by section after production is complete, to avoid confirmation bias. Entries that fail the audit are rewritten or withdrawn. No entry is published with a known critical error.
An authentic voice
Each language version of Osmetheca receives original writing, never translated, adapted to the local perfume culture: cultural references, emblematic perfume examples, dominant perfumery traditions and authority sources vary by market. No content is translated from one language to another.
