Today I was playing around with W3C Annotation AKA Web Annotation. I needed to convert the JSON-LD examples to RDF XML and test XPath expressions. I justed a couple of online tools. Just some quick notes about these tools.

• Convert JSON-LD to RDF XML: Select JSON-LD as input format and Pretty RDF/XML as output format.
• Test XPath expressions: Copy and past the XML into the input field. Type the XPath into the XPath input field. Hit Test XPath button and you should see the result.
• XML Formatter: A XML formatter that lets you specify the number of leading spaces.

You can find the latest information about Web Annotation over here and example code on Github.
