Introduction[edit]
This page should give a short overview on browser-related requirements. As a rough approach it was decided to support browsers with respect to layout consistency only 3 years back. Older browsers like IE 5,5.5 FF1.x should offer the functionality but with limitations on the GUI.
Supported Browsers[edit]
name | version | release date | used by[1] | market share[2] | Layout supported | Functionality available |
---|---|---|---|---|---|---|
Internet Explorer | 5.01 | 1999/12 | 34.9 % | 0.6% | not required | yes |
5.5 | 2001/10 | <1% | not required | yes | ||
6.0 | 2001/10 | 10.8% | yes | yes | ||
7.0 | 2006/10 | 23.7% | yes | yes | ||
8.0 | 2009 | <1% | not testable|yes | yes | ||
Firefox | 1.x | 2005/12 | 39.6 % | <1% | not required | yes |
2.0 | 2006/10 | 5.1% | yes | yes | ||
3.0 | 2008/07 | 28.4% | yes | yes | ||
4.0 | 2009 | 0% | not testable | yes | ||
Safari | 2.0 | 2005/04 | 2.9% | 2.8% | not testable|yes | yes |
3.0 | 2007/06 | yes | yes | |||
Opera | 9.x | 2006/06 | 0.96% | 0.5% | not required | yes |

- To fulfill the requirements from the DFG , following further browser versions have to support the functionalities of ViRR (see Praxisregeln im Förderprogramm "Kulturelle Überlieferung"):
- Opera ab 7.0
- Firefox ab 1.0
Required web techniques[edit]
name | version | release date | activation[3] | required |
---|---|---|---|---|
Cascading Style Sheets | 1.0 | 12/1996 | 100%[4] | required |
2.0 | 05/1998 | specials only[5] | ||

Cookies | - | - | 98.5% | required[7] |
JavaScript | 1.5 | 06/2002 | 94,0%[8][9] | required |

Screen Solution Optimization[edit]
screen solution | used by[12] | optimized for |
---|---|---|
800 / 600 | 2.9% | scroll only[13] |
1024 / 768 | 44.2% | optimized |
1152 / 864 | 4.0% | should be ok |
1280 / 1024 | 35.8% | should be ok |
1600 / 1200 | 2.5% | should be ok |
Enlargeable font size[edit]
The font size can be enlarged by the user without limitations to content, readability or GUI design within the following range limitations:
font/box size steps | Text | Application Layout |
---|---|---|
larger | not supported | not supported |
4x - 8x | readable but not nice | divergent |
1x - 4x | readable/no overlappings | small divergence |
Graceful degradation[edit]
This is only a rough overview on what should be supported. For a more precise definition of requirements (BITV) see: GUI Accessibility
Degradation of Navigation
The eSciDoc GUI makes use of skip links, important to users equipped with screen readers and text browsers or conservative browser settings. The skip links allow to jump to navigation or content.
Degradation of Style (CSS)
Style | Usability | Specialities |
---|---|---|
No application layout | The eSciDoc GUI shows all relevant controls. All Controls can be operated properly. All HTML Elements are lined up in structured manner and can still be identified |
Degradation of Java Script
Style | Usability | Specialities |
---|---|---|
Some controls (input) are set back to browser default but application layout is kept | Each control can be operated properly |
Media Types[edit]
Type | Style | Usability | Specialities |
---|---|---|---|
Navigation is not printed | Content is readable | None | |
Mobile | Device/Browser dependent (textmode via CSS degadation) | Device/Browser dependent | None |
