To be complete
Osmetheca has a simple ambition: to cover niche perfumery in its full extent, and to answer precisely every question one might ask about it. A living encyclopedia of materials and olfactory families. A technical glossary without equivalent. Serious portraits of creator perfumers and independent houses. Dense, structured perfume entries. Practical guides for newcomers, and a Journal for those already deep in the passion.
When you look for a precise answer to a simple question about oud, Taif rose, the Italian school, or the signature of an independent house, you should be able to consult a single dense, structured, and verified source. That is what Osmetheca offers.
Six writing principles
Six principles shape the writing of every entry on the site.
Factual density
Every entry offers dense, organized, verifiable information. Concision is never the enemy of precision.
Explicit sources
Every factual claim points to a named authority source. Nothing is asserted without support.
Terminological consistency
Vocabulary stays constant across the whole site. Glossary definitions hold for the Encyclopedia, the perfume entries, the Guides, and the FAQ.
Description and opinion kept apart
Descriptive entries aim for objectivity. The Guides take on teaching. The Journal claims a subjective voice.
Documentary honesty
No invented date, no fanciful perfumer, no fabricated classification. When information cannot be verified, it stays out of the entry.
Entries that complete each other
A perfume entry points to its house, its perfumer, its olfactory family, and its raw materials. Understanding is built through cross-references.
Where the information comes from
Verification draws on sources ranked by decreasing authority for each type of claim.
French institutional sources
- Societe Francaise des Parfumeurs: official olfactory classification, perfumer biographies
- ISIPCA Versailles: reference framework for perfumery training
- Osmotheque, Versailles: world conservatory of perfume, historical reconstructions, pre-IFRA formulations
International regulatory and industry sources
- IFRA: restriction standards for materials and allergens
- RIFM, ECHA, CITES: toxicology, REACH, and protected materials
- Industry houses: Givaudan, Firmenich, IFF, Symrise, Mane, Robertet, Takasago
Critical and community sources
- Official house websites: top priority for founding dates and perfumer lineages
- Expert blogs: Bois de Jasmin, Now Smell This, Persolaise, Cafleurebon, The Perfume Magpie
- Community databases: Fragrantica, Basenotes, Parfumo (read with critical distance, never as a sole source)
A systematic factcheck
Before publication, every entry passes a careful audit. Founding dates, perfumer names, launch years, olfactory classifications, IFRA restrictions, and CITES status are all checked against a source.
Three error levels are distinguished. Critical errors (a wrong date, an incorrect perfumer attribution, a false classification) are not tolerated. Intermediate errors stay under 5%. Minor errors stay under 10%. No entry is published with a known critical error.
A clear corrections policy
No method removes every risk of error. When an inaccuracy is reported or detected, it is handled with the same rigor as initial production: cross-checking against three independent sources, absolute priority given to primary sources (houses, perfumers, professional institutions), and a correction published on the entry itself with an updated modification date.
Critical errors are corrected as soon as they are confirmed. Interpretive nuances are reviewed and rephrased where needed. Anyone can report an inaccuracy through the contact page: every documented report receives a reply and a follow-up.
An authentic voice
Each language version of Osmetheca receives original writing, never translated, adapted to its local perfume culture: cultural references, signature perfumes, dominant schools, and authority sources vary by market. No content is translated from one language to another.
