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.
✓ 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.
What the DOI identifies

"value": "Nodulation in legumes provides a major conduit of available nitrogen into the biosphere. 25 geo-specific rhizobium isolates in relation to five legume plant varieties were tested with combinations under gnotobiotic conditions for improving nodulation and plant growth through inoculation in field trials for the unraveling and amelioration of sustainable plantations in barren, polluted and agriculture soils. Interestingly, strains from Bhadrachalam forest were found to be highly host specific for Albizzia lebbeck, Sesbania grandiflora and Pongamia pinnata and strains from Jakaram and Kothagudem forests were shown host specific for Gliricidia maculata and Acacia nilotica, respectively. This method can employ across the country for green revolution.",
