The problems users face when working with the XSD standard can be mitigated with the use of graphical editing tools. Although any text-based editor can be used to edit an XML Schema, a graphical editor offers advantages; allowing the structure of the document to be viewed graphically and edited with validation support, entry helpers and other useful features.
XML validation is the process of checking a document written in XML (eXtensible Markup Language) to confirm that it is both well-formed and also "valid" in that it follows a defined structure. A well-formed document follows the basic syntactic rules of XML, which are the same for all XML documents. [ 1 ]
Schema.org is an initiative launched on June 2, 2011, by Bing, Google and Yahoo! [ 3 ] [ 4 ] [ 5 ] (operators of the world's largest search engines at that time) [ 6 ] to create and support a common set of schemas for structured data markup on web pages.
After XML Schema-based validation, it is possible to express an XML document's structure and content in terms of the data model that was implicit during validation. The XML Schema data model includes: The vocabulary (element and attribute names) The content model (relationships and structure) The data types; This collection of information is ...
XSD schemas are conventionally written as XML documents, so familiar editing and transformation tools can be used. As well as validation, XSD allows XML instances to be annotated with type information (the Post-Schema-Validation Infoset (PSVI)) which is designed to make manipulation of the XML instance easier in application programs. This may ...
The SHACL Test Suite and Implementation Report [7] linked to from the SHACL W3C specification lists some open source tools that could be used for SHACL validation as of June 2019. By the end of 2019 many commercial RDF database and framework vendors announced support for at least SHACL Core. Some of the open source tools listed in the report are:
Liquid XML Studio IDE is a Windows based XML editor and XML data binding toolkit. It includes graphical editors for authoring XML, XML Schema, WSDL, XSLT and HTML.It also includes user interface extension to Microsoft Visual Studio through the Visual Studio Industry Partner (VSIP) program.
It was proposed at the 2012 RDF Validation Workshop [3] as a high-level, concise language for RDF validation. The shapes can be defined in a human-friendly compact syntax called ShExC or using any RDF serialization formats like JSON-LD or Turtle. ShEx expressions can be used both to describe RDF and to automatically check the conformance of RDF ...
