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.

"value": "Waste water treatment is essential to re use of used water. In this paper we discuss about the waste water treatment , process and various techniques used for the treatment process. Waste water treatment is also important factor for safety of the environment conditions. To make the environment free from hazardous conditions and to make the sustainable environment. It is also controls different types of pollutions in the water. It is eco friendly in nature. Waste water engineering is the branch of Environmental engineering. which deals with occurance, distribution and treatment of waste water and recycle use of waste water. It also used for study of design construction of structures related to supply of potable water towards public. To prevent water borne diseases from the water. It is also used for disposal of waste water by selecting suitable locations . the study of waste water is also important to understand the various types of pollutions in the soil. This knowledge helps to better usage of water and disposal of the water",
