  • 25. Critic - Conclusions• Halo extension constrains the WSSW, and in general the implemented wiki, to use only its data.• No external endpoint can be called to import the query’s results in WSSW pages.
  • 26. Future Work ImplementationUse SPARQLExtension as soon as it is stable to call external endpoints.Move to LinkedWiki or other extension which implements queries to external endpoints and embeds them in wiki’s pages!Embed content derived as SPARQL queries to WSSW’s pages from related external endpoints.
  • 27. Future WorkUse Semantic Signup extension to semantically annotate every new user!Annotate courses and the educational objects they provide using the proper codes from the corresponding Scientific Classifications in SKOS format. ACM Classification Mathematics Subject Classification
