JSON Schema specifies a JSON-based format to define the structure of JSON data for validation, documentation, and interaction control. It provides a contract for the JSON data required by a given application and how that data can be modified. [29] JSON Schema is based on the concepts from XML Schema (XSD) but is JSON-based. As in XSD, the same ...
A SHACL validation engine takes as input a graph to be validated (called data graph) and a graph containing SHACL shapes declarations (called shapes graph) and produces a validation report, also expressed as a graph. All these graphs can be represented in any Resource Description Framework (RDF) serialization formats including JSON-LD or Turtle.
XFDL also provides a syntax for in-line mathematical and conditional expressions and data validation constraints as well as custom items, options, and external code functions. Current versions of XFDL (see Specifications below) are capable of providing these interactive features via open standard markup languages including XForms, [ 2 ] XPath ...
Schema.org is a reference website that publishes documentation and guidelines for using structured data mark-up on web-pages (called microdata).Its main objective is to standardize HTML tags to be used by webmasters for creating rich results (displayed as visual data or infographic tables on search engine results) about a certain topic of interest.

The Schema Subset Generation Tool (SSGT) enables users to search through the NIEM data model, view information about NIEM elements and types, and build a custom XML Schema subset of a NIEM release. The NIEM data model contains over 12,000 elements and represents over a dozen domains; subsets allows users developing an IEPD to select only what ...
JSON web tokens may contain session state. But if project requirements allow session invalidation before JWT expiration, services can no longer trust token assertions by the token alone. To validate that the session stored in the token is not revoked, token assertions must be checked against a data store. This renders the tokens no longer ...
Validation metadata include data type, range of permissible values or membership in a set of values, regular expression match, default value, and whether the value is permitted to be null. In EAV systems representing classes with substructure, the validation metadata will also record what class, if any, a given attribute belongs to.
The process of checking to see if a XML document conforms to a schema is called validation, which is separate from XML's core concept of syntactic well-formedness.All XML documents must be well-formed, but it is not required that a document be valid unless the XML parser is "validating", in which case the document is also checked for conformance with its associated schema.
