Comment on RDFa Primer

This isn't a big deal, but I thought that the abstract of the document could use a little editing (not that my version is worthy of a Pulitzer). Here's my revision:

Abstract

This document is an introduction to the RDFa syntax for expressing structured data in XHTML. Currently web pages written in HTML contain significant user defined data, but the data is not accessible outside of the publisher's domain. A new world of functionality becomes available when publishers can standardize the expression of their data, and when tools can read it, letting publishers and subscribers easily transfer data between applications and web sites. 

Using RDFa syntax to standardize data expression in XHTML, data can be reused and publishers can avoid duplicating work. The underlying abstract representation is RDF, which lets publishers build their own vocabulary, extend others, and evolve their vocabulary with maximal interoperability over time. The expressed structure is closely tied to the data, so that rendered data can be copied and pasted along with its relevant structure. The end result is that an event on a web page could be directly imported into a user's desktop calendar; a copyright notice on a document could be detected so that the user is informed of his rights automatically; or a photo's creator, camera setting information, resolution, and topic could be published as easily as the original photo itself, enabling structured search and sharing.

A more detailed syntax specification is being produced.
