    The OAW Tracker is the tool that allows the Government of Spain perform the different iterations of the Web Accessibility Observatory (OAW) and the usage of the online diagnosis service available from the Accessibility Community . The OAW Tracker allows the accessibility verification of a website and generates the automatic reports taking in consideration almost 100 check-points implemented in the platform, and also provide recommendations about how to solve the detected problems.

    The accessibility review of the OAW is performed by an automatic methodology based on the UNE 139803:2012 (WCAG 2.0) standard , developed ad-hoc for the Web Accessibility Observatory. This methodology has into account 20 accessibility checks. Each check is composed by many checks (more than 100) that are automatically executed. In addition, it includes other automatic checks, using specialized rules, which are usually perform manually.

    The OAW Tracker allows the configurations of all the needed parameters to perform one observatory iteration (list of web portals, web pages per portal, methodology, frequency, etc) and also allows to perform and to review all the execution process. Furthermore, it allows the generation of the conclusions reports and the needed results, to obtain the accessibility overall view in one sector and also to obtain the detailed reports for each web portal containing all the existing problems.

    In addition, the OAW Tracker is used by the online diagnosis service available in the Accessibility Community in order to obtain an estimation, under demand, of which will be the results in an official iteration, ease the future correction and comparison of the possible errors present in the web portal.

    The OAW Tracker analyse two times in a year more than 700 web portals, which means roughly the analysis of 25.000 web pages in a year. Also, through the online diagnosis service it’s requested the analysis of more than 60.000 web pages per year.

    From the technological point of view, this product has been built using free software tools and its provision is possible thanks to free software tools like apache, tomcat, mysql, etc. This tool has been initially developed by INTECO (National Communications Technology Institute). When this institute was converted to  INCIBE(Abre en nueva ventana) (Spanish National Cybersecurity Institute) all the source code and materials were transferred to the Ministry of Finance and Public Function which has been using and evolving the project, and now, has released the product and has offered it to all the  possible stakeholders.

    This tool could be used by other States or Institutions to perform periodically accessibility reviews for a lot of web portals, aligned with the requirements of the Directive (EU) 2016/2102 of the European Parliament and of the Council of 26 October 2016 on the accessibility of the websites and mobile applications of public sector bodies .
