Background - What is EASTIN
• A European network that offers information on Assistive Technologies of all kind (mobility, self care, ICT, ….)
• The core is the EASTIN website www.eastin.eu that includes information on assistive technology products, manufacturers and associated info (articles, case studies, …)
• EASTIN stems from a project founded by the European Commission in 2004-2005 (eTEN programme)
• Now is a self financing association
• EASTIN is currently expanding (including new information providers), and improving the dataset for the description of products

Output Web Service Server
Two methods are available:1. BasicProductInfoDto[] FindProductsSortBySimilarity (string isoCodes, string commercialName, string manufacturer, string insertDateMin, string insertDateMax, string baseForSimilarity, string features)
This method is used to search for products in the databases of the EASTIN network according to the specified parameters. The method returns an array of “BasicProductInfoDto” including the basic product information (name, ISO 9999 code, manufacturer, ….). The methods also allows to evaluate the similarity of a product record (selected as “base for similarity”) with all the other products found.The method is available at the url: http://webservices.eastin.eu/cloud4all/searches/products/listsimilarity
2. ProductDetailsDto GetProduct(string database, string productCode);
This method is used get the detailed description of a specific product in one of the databases of the EASTIN network. The method returns an object belonging to the class “ProductDetailsDto”The method is available at the url: http://webservices.eastin.eu/cloud4all/searches/products/detail/
Output Web service Client
1. The Client Web Service calls the FindProductsSortBySimilarity method passing as input parameter an array of ISO 9999 codes. For example the REST call will be:http://webservices.eastin.eu/cloud4all/searches/products/listsimilarity?isoCodes=223618-223912 An array of BasicProductInfoDto is returned.
2. For each of the product record returned by the FindProductsSortBySimilarity method the GetProduct method is called (passing as parameter the ProductCode and Database)For example the REST call will be:http://webservices.eastin.eu/cloud4all/searches/products/detail/siva/19509

Validation procedure
1. Find out duplicated products (aided by automatic functions)
2. Information of duplicates is merged into one record (automatic procedure) that will include:
– all the commercial names (alias)– all the manufacturer names– all the ISO codes– all the images– all the text descriptions– the sum of the detailed information
3. if needed, technical data are completed/modified and feedback is sent to the information provider
4. Specific settings are added
See wiki page: http://wiki.gpii.net/index.php/Unified_%28Federated%29_Listing_validation_procedure

“input” Web services protocol
• Protocol: XML-SOAP 1.2
• SIVA Web Service for Eastin is an example of implementation based on Microsoft .NET Windows Communication Foundation (WCF) technology. Other Eastin partners used Java-based or PHP-based frameworks. Here you can get the WSDL of SIVA Web Service for Eastin: http://www.portale.siva.it/eastinetnawebservices/searches.svc?wsdl
“input” Web services product search function
The Web service must implement 9 functions. The most important function in Cloud4all repository perspective is:
SmallProductDto[] FindSmallProducts(string[] isoCodes, FeatureDto[] features,
string commercialName, string manufacturer, DateTime insertDateMin, DateTime insertDateMax);
features parameter is an array of FeatureDto objects that represent the new Eastin-Etna taxonomy (from Jan 2013) and can be used together with isoCodes parameter to find all ICT products caracterized by a specified techincal feature.
“input” Web services returned object 1
The function returns an array of SmallProductDto objects which are defined here:
public class SmallProductDto{
public string ProductCode { get; set; }public string IsoCodePrimary { get; set; }public string[] IsoCodesOptional { get; set; }public string CommercialName { get; set; }public string ManufacturerCode { get; set; }public string ManufacturerName { get; set; }public DateTime InsertDate { get; set; }public DateTime LastUpdateDate { get; set; }public string ThumbnailImageUrl { get; set; }
}
“input” Web services product detail function
Once you get the product ID (called ProductCode) you can get all the possible information about a single product calling the function:
ProductDto GetProduct(string productCode, string languageCode);
The languageCode parameter (for ex.: “en”, “it”, “de”) is used to decide how to localize some of the textual content contained in the returned object.
“input” Web services returned objects 2
The ProductDto returned object is defined here:
public class ProductDto { <... all fields contained in SmallProductDto plus ... > public string ManufacturerAddress { get; set; } public string ManufacturerPostalCode { get; set; } public string ManufacturerTown { get; set; } public string ManufacturerCountry { get; set; } public string ManufacturerPhone { get; set; } public string ManufacturerFax { get; set; } public string ManufacturerEmail { get; set; } public string ManufacturerSkype { get; set; } public string ManufacturerWebSiteUrl { get; set; } public string[] ManufacturerSocialNetworkUrls { get; set; } public string ImageUrl { get; set; } public string Description { get; set; } public string OriginalUrl { get; set; } public string DownloadUrl { get; set; } public string[] UserManualUrls { get; set; } public string[] VideoUrls { get; set; } public string[] BrochureUrls { get; set; } public string[] FurtherInfoUrls { get; set; } public FeatureDto[] Features { get; set; } }
