Nice paper.  An idea to add CORS?


[reproduced for convenience] ...

What is this about?

CORS is a specification that enables true open access across domain boundaries.

Why is this important?

Currently, client-side scripts (e.g., Javascript) are prevented from
accessing much of the Web of Linked Data due to "same origin"
restrictions implemented in all major Web browsers.

While enabling such access is important for all data, it is especially
important for Linked Open Data and related services; without this, our
data simply is not open to all clients.

If you have public data which doesn't use require cookie or session
based authentication to see, then please consider opening it up for
universal javascript/browser access.

For CORS access to anything other than simple, non auth protected
resources please see this full write up on Cross Origin Request
How can I participate?

To give Javascript clients basic access to your resources requires
adding one HTTP Response Header, namely:

 Access-Control-Allow-Origin: *

This is compatible with both XHR XMLHttpRequest and XDR
XDomainRequest, and is supported by all the major Web browsers.
