Kernel Metadata Declaration — on demand

ISO 26324 asks a DOI Registration Agency to produce a Kernel Metadata Declaration for every DOI it issues. Give any DOI: its public record becomes a record in the Smart Scholars DOI Metadata Format 1.0, checked against every rule, and declared as the Kernel XML.

Reads the DOI's public Crossref record; nothing is stored. Until Smart Scholars is accredited, every Declaration is marked as a draft in the XML itself.

✓ Meets every rule of the format

The record below is complete and every controlled value is a DOI Attribute Value Set 2.3 spelling. The Declaration on the right follows DOIMetadataKernel.xsd element by element.

Herbal medicines have been used for many years because of their mild side effects, suitability, and influence. Citrus is a liquid plant in the family of Rutaceae. In the genus citrus, approximately 140 genera and 1300 species are present. The word lemon comes from \"limon\" in ancient French. There are several other lemon fruit names available. The main components of the chemical makeup are flavonoids, acids, caffeine, pectin and minerals. Many ingredients contain basic citrus oil, and limonene is the main ingredient in its odour. Lemon has many qualities, such as antimicrobial, antifungal, anti-inflammatory, anti-cancer, depurative, antiscorbutic, etc. Lemon essential oil is toxic, especially in pregnancy, breastfeeding and radiation exposure.
