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.

        "value": "Our goal was to determine the limnological differences and biodiversity of plankton in two separate lentic ponds in connection to aquaculture. From December 2020 to February 2021, water samples and plankton samples were collected and analysed.The obtained samples contained six distinct species of phytoplankton, including Oscillatoria sp., Spirulina sp., Anabaena sp., Chlorella sp., Volvox sp., Spirogyra sp., and eight different species of zooplankton, including Cyclops vernalis , Oithona rigida, Eucyclops se rrulatus, Oithona rigida , Eucyclops serrulatus , Oithona similis , Oithona nana , Daphnia duplux, Brachionus bruben, Branchionus sp,were observed in the collected samples.The BOD values in the six samples ranged from 6.85 to 7.40 mg/L. This suggests that ther e is a significant amount of organic contamination. In December 2020, all limnological parameters were average, which is necessary for plankton growth and fish survival. In January and February 2021, the limnological parameters increased somewhat, and the level of plankton in both ponds increased.As a result, these two freshwater ponds might be suitable for aquaculture",

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.
