Several educational registries (e.g. Schoolforge or Ontoolsearch) provide information about ICT tools in order to help educators when discovering and -which limits their utility- is how their data is sustained, since educational descriptions of ICT tools are hard to create and maintain updated. In order to overcome this problem, some registries (e.g. Cool Tools For Schools) involve their communities of users in their sustainment, following a social approach. Unfortunately, three important drawbacks can be found in these registries: first, the well-known cold-start problem is present; second, their data models can not typically describe information about the educational use of ICT tools; third, these registries are isolated data silos that need to create and keep updated all the data they manage, thus increasing the overall effort of sustaining educational ICT tool datasets. For this reason we propose We-Share, a social annotation application that allows educators to search, create and enrich descriptions of ICT tools from the Web of Data. This characteristic enables We-Share to count with an initial dataset of 6760 ICT tool descriptions automatically gathered from the Web, which are automatically updated by periodically crawling the Web of Data. Further, We-Share enables the community of educators to enrich its dataset reviewing ICT tools and relating them to the educational contexts where they were employed. All the data published on We-Share is available as Linked Open Data.
