Where can I find a good turtle editor?
Many RDF editors can save to Turtle or N3 format. Protege, a free open source editor is available from http://protege.stanford.edu/. TopQuadrant's TopBraid Composer is available from http://www.topquadrant.com/products/TB_Composer.html
What if I have RDF data, but it is in another format such as RDF/XML?
There are conversion tools such as the morph Semantic Converter from Talis. Editors such as Protege and TopBraid Composer can also read and save various flavors of RDF.
Do I need to include the TurtleScript and ANTLR JavaScript libraries in my web page to use TurtleScript?
You need to include the libraries if you want to access the semantic information from your JavaScript. Third party tools are able to read and use the semantic data in your web page even if the libraries are not there.
Are there any validators for turtlescript?

There is a simple online validator for Turtlescript at turtlescript.appspot.com.

There are several online validators for Turtle, such as the RDF Validator and Converter.

An offline validator for TurtleScript is on the roadmap to be added to the project.

What are some other ways of embedding semantic data in web pages?

Microformats are a technique for embedding semantic data in the CSS styles of an HTML document. It is not an RDF syntax, but conversions exist.

RDFa is a way to embed RDF data in the CSS styles of an HTML document. The semantic information is spread throughout the HTML.

GRDDL is a way for web sites to provide XSLT stylesheets to convert their XHTML pages to RDF format.

Data can also be stored in an HTML document in the form of JSON, XML, or other formats. There are no standard conversions of such data to semantic web formats, though custom conversions are often possible.

Where can I find information about the specific microformats used in the Turtlescript examples?
hCalendar is defined at http://microformats.org/wiki/hcalendar. hCard is defined at http://microformats.org/wiki/hcard. A list of canonical conversions between RDF and microformats is available at: http://semanticweb.org/wiki/Microformats_in_RDF.
What software libraries currently read TurtleScript?

No libraries currently read TurtleScript out of the box. It is designed to be easy to read the turtle script from an HTML file. Many libraries are then able to read (and write) the Turtle syntax.

Libraries that can read Turtle include: Jena, Redland and RDFlib.
