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.

What the DOI identifies

Synthesis, Characterization & Antimicrobial activity of several Quinazolinone Schiff bases, 7-hydroxy-10,11-dihydroindeno[5,4- c]chromene-6(9H)-one & their Cu(II) complexes

In addition, the ligands, complexes, metal salt and control were tested in vitro for their biological activities against gram positive and gram negative micro organism. The results indicated that the metal complexes showed significantly higher activities compared to the free ligands and metal salt",

Everything Smart Scholars runsNine sites, one account. A journal starts at the audit; an author starts at Scholar Shield.

For journals & publishers

Start with the audit — it is free, and it is the gate to everything else.

DOI care

Nine services on one journal profile — each previews first and acts only on your approval.

For authors & researchers

Free to use. Nothing you check is shared with the journal.

For institutions, sponsors & DOI operators

Smart Scholars

Mon–Sat, 10:00–19:00 IST. The Ask AI button on every page answers about our services at any hour.
