The plug-ins Data gathered in Adnosco is completely independent from the applications through which they were acquired. Currently, we focus on data filled in web forms by the user. User data should be extracted to be stored at the users' side. This functionality has been implemented as a browser plug-in as it should act as an intermediary between the web browser and the other components of Adnosco. Moreover, as each browser has its own features and the implied technologies used in web forms differ from one site to another, the solution to propose one plug-in for each browser minimize technical problems. On user's demand, the plug-in also interacts with Adnosco core to get completion proposals and to propose them in a human friendly way to the user. It also includes a GUI to semantically qualify web forms on the fly and another one is devoted to query data.%the role to is then to extract data on web form validation and to send the extracted data to Adnosco to be stored

Data storage module It stores all the collected data and Adnosco informations. This includes data extracted in web forms by the plug-ins, semantic models, semantic qualifications and so on.

Data management module This module provides an API to interact with clients, actually the adnosco plug-ins. It includes two main functionality: to store and to query data. A specialized API has been developed to manage specific queries related to form completion. This API proposes different solutions based on syntactic but also semantic and similarity considerations.
