Web Standard: Standard Web Formats and Proprietary Formats
Definitions
Programs create different kinds of files which are published to various formats. They have different file extensions (e.g.; .pdf, .doc, .pptx). These files are rarely updated and are more likely to become redundant, outdated or trivial. Consider carefully before publishing these types of files.
Content Requirements
- The EPA standard formats for publishing information on the Web are HTML and PDF.
- Proprietary formats (.wpd, .doc, .xls, .ppt) should be used only when necessary (e.g., when providing forms for customers to complete and submit or for spreadsheets that they will use).
- Video and audio files should include run time. Examples:
- Podcast Title (.mp3) (03:35, 256K)
- Video Title (.wmv) (02:25, 3.4MB)
- Add proprietary format disclaimer and link to the EPA formats page.
- Option 1: Multipurpose box contains: You may need additional software to view some of the links on this page. See EPA’s Free Viewers and Readers page.
- Option 2: Inline disclaimer (e.g.): Document Title (doc) (xx pp, xxK) Free Viewers
