Awesome Semantic Web

A curated list of various semantic web and linked data resources.

To add something to the list please either submit a pull request or add a comment with a link to issues/awesomelets. Pull requests will be evaluated immediately for inclusion while awesomelets will be evaluated at some indeterminate time in the future.

Looking for something but can't find it? Add it to the "Does it exist" list and we'll keep an eye out for it. If it's a good idea maybe someone will come along and create it!

RDF Datatyping - This document summarizes the common understanding of the RDF Core Working Group (further referred to as WG) with regards to the theoretical foundation for datatyping of literal values and serves as a basis of definition, discussion, and comparison of all proposed schemes for achieving a complete datatyping solution which are to be considered by the WG.
