WP 203 – Federating reposit. of solution and components

Activities started in May 2012 (till August 2015)

Objectives in the DoW• To develop (the methods for maintaining) a single entry point for the retrieval of the information and data required to implement appropriate assistive solutions.•The creation of efficient mechanisms for search and retrieval of accessible services and applications that will be provided in the envisioned Cloud infrastructure• Integrate the information on assistive solutions into the GPII unified listing and marketplace.

Page 3: WP 203 - Federating repositories of Solutions and Components

Federated repository of Assistive solution within the GPII vision

A way for users to find all of the solutions that exist and to figure out which ones meet their needs.

Page 4: WP 203 - Federating repositories of Solutions and Components

Federated listing of AT devices

The Cloud4All Federated Repository of avaliable AT solutions will represent one of the sources of information for: 1. The GPII Unified Listing – a comprehensive listing of free and commercial,

open and proprietary source, assistive technologies and features in mainstream products

2. The GPII Marketplace - i.e. a marketplace for "purchasing" commercial and free Access solutions

3. The GPII “shopping aid” that helps the user to find the most appropriate assistive solutions in the unified listing and marketplace

4. The semantic framework for contents and solutions ?/ The matchmaker: one source of information used by the Matchmaker to propose activation of installed AT as well as installation of Assistive technology not yet available locally (see use cases 11-12 D101.2)

The starting point – the EASTIN network

The starting point for the Solution Database is the EASTIN web portal

Activities led by FDCGO

•A 203.1: Approach and mechanism for federating solution repositories•Definition of a method to harmonize and efficiently retrieve data coming form distributed databases

• A 203.2: Integration of the appropriate subsections of federated data with the GPII Marketplace•Develop and demonstrate the ability to extract relevant information from more general topic disability databases

+

•A 202.4 Toolbox for professional and vendor entry and maintenance of Metadata •Implement an application suite for the manual creation, maintenance and update of metadata, based on the developed semantics framework

Page 12: WP 203 - Federating repositories of Solutions and Components

• Challenges• Harmonize the content coming from different sources and avoid

duplication of data in the federated repository (the same product could be stored in different DBs)• Maintenance/update of data (ICT products become obsolete very

fast) => distributed-collaborative update, update by vendors • Maintenance/update of ontologies and metadata (e.g. when new

technologies become available) => automatic generation of metadata• Evaluate/validate the quality of the information (is the

information correct, complete and accurate) => responsibility of each distributed information source• Clearly mark (and credit) the source of information

What is what

• Cloud4all Federated Repository : This is a federated repository of open source and commercial AT of many types, based on the (distributed) databases of AT

• The GPII Unified Listing : This is a federated repository of open source and commercial AT related to ICT access as well as access features in mainstream products

• The GPII Marketplace :The GPII Marketplace is a place to buy some ICT access products (those that the developers would like to distribute this way). The GPII Marketplace has a "shopping aid" that will draw from Cloud4all work

• The Cloud4all/GPII Solutions Database: In the Cloud4all/GPII architecture - there is reference to two different "Solutions databases”:1. a database of solutions that are present at a particular device that a user is at. This

lists all the local solutions that are available to the user2. a database of information about (ideally all) devices. This can be used by the

matchmaker to determine what features are available for any device that a user might encounter. It allows the matchmaker to know what features are available if the device does not offer up any more information than just its name/make/model. (is this the Semantic Framework of Content and Solutions ?)
