4-Step NewsML-G2 + XHTML5 + Microdata + NITF Validator

How it works

The validation is performed in three independent steps:

1. NewsML-G2 validation based on the XSD provided by IPTC.
2. XHTML validation of the inlineXML embedded XHTML document withing the NewsML-G2 contentSet, using XML schemas for XHTML1 and XHTML5
3. Validation of microdata, embedded within the XHTML document, using Google Structured Data Testing Tool https://developers.google.com/structured-data/testing-tool/
4. Validation of NITF embedded into inlineXML elements

Validation API

Validation without using the graphical interface can be done by sending a POST request, containing the NewsML-G2 document in the POST body to the same URL as this page.

Alternative validation services

You can choose between a couple of services to validate HTML5 and Microdata. Please remember to add the right doctype definition to your XHTML document in order to make the validator recognize this is a polyglot HTML5 document ()

###HTML5 validation http://validator.w3.org/, The W3C Markup Validation Service https://validator.nu, validator.nu

###Microdata validation https://developers.google.com/structured-data/testing-tool, Google Testing Tool, https://webmaster.yandex.com/microtest.xml, Yandex Structured Data Validator http://www.bing.com/toolbox/markup-validator, Bing Markup Validator
