Fundación Sidar offers this tool free of charge to developers, designers and the public in general, to simplify the manual revision of webpages' and websites' accesibility.

HERA is designed and developed by Carlos Benavídez for Fundación Sidar, with contribution from Emmanuelle Gutiérrez y Restrepo and Charles McCathieNevile.

Where does HERA name come from? At the beginning of 2003, Sidar Fundation launched Edipo, a tool for personal stylesheet creation and, already in that moment, we thought about a "sister" utility based in stylesheet application to simplify the review of accessibility. As Edipo is a mythological character, we looked for a similar name for this new aplication and we decided for HERA, which besides being the name of another femenine character, conforms the acronym for: "Hojas de Estilo para la Revisión de la Accesibilidad." (Accesibility Revision StyleSheets)

Objetive and functionality

HERA´s objective is to simplify the work of those who wish or have the mission of reviewing the accesibility of a page or a web site. A review can never be complete without a manual review. Automatic review tools can only detect determined elements and attributes bat cannot ensure they´re properly used. Therefore, it´s indispensable a human´s participation in order to check the elements and attributes that cannot be automaticaly validated and if Accessibility Guidelines are being properly applied.

HERA simplifies finding errors in a page, applying a stylesheet specially created for that purpouse, and explains what to look for to test a each checkpoint.

In HERA´s help, you´ll find detailed information about how it works.
