HTML-hul Module

1 Introduction

The HTML-hul module recognizes and validates the HTML (Hypertext Markup Language) format. [HTML].

The module is invoked by the:

    jhove ... -m HTML-hul ...
  

command line option.

The HTML-hul module recognizes XHTML 1.0 (including transitional, frameset and strict) and 1.1, making use of the XML-hul module. If the XML-hul module is not available, only limited information will be provided on XHTML documents.

This module can be configured with the following parameters:

• withTextMD=true to ask for the output of a textMD block in the text technical properties.

2 Coverage

The HTML-hul module recognizes and validates the following public profiles:

• HTML 3.2, and 4.0 and 4.01 (Strict, Transitional, and Frameset) [HTML 3.2, HTML 4.0, HTML 4.01]
• XHTML Basic and 1.0 and 1.1 (Strict, Transitional, and Frameset) [XHTML Basic, XHTML 1.0, XHTML 1.1]

3 Well-Formedness

For the HTML profiles JHOVE uses the criteria for HTML well-formedness defined by [HTML 3.2, HTML 4.0, HTML 4.01]; for the XHTML profiles, JHOVE uses the criteria defined by [XML]. Specifically, a well-formed HTML document must have no syntactic errors, and must contain at least one of the tags HTML, HEAD, BODY or TITLE.

4 Validity

For the HTML profiles JHOVE uses the criteria for HTML validity defined by [HTML 3.2, HTML 4.0, HTML 4.01]; for the XHTML profiles JHOVE uses the criteria defined by [XHTML 1.0, XHTML 1.1].
