This post contains the first set of results from my SPARQL extension survey. I’ve completed an initial survey of a number of different SPARQL processors to itemise the extension functions that each of them have implemented. This will be an ongoing activity as implementations evolve continually, but I thought it would be useful to summarise my findings so far. If you want to look at the results for yourselves, then I’ve created a publically accessible Google Spreadsheet that lists all of the results. The first tab of the spreadsheet includes the list SPARQL endpoints/processors that I’ve surveyed. SPARQL Extension Function Survey Summary ? Lost Boy
Annotator | Open Knowledge Foundation Adding annotation to your webpage using the Annotator is easy. Full instructions are in the Getting Started section of the docs, but it is just two short steps. First, you need to download the Annotator library (or link to the hosted version), include it on your page along with jQuery. Then add the following line to initialize the annotator. $('#content').annotator(); Plug-ins can be included for adding functionality such as user accounts, tags, filtering and formatting.
DBpedia is a crowd-sourced community effort to extract structured information from Wikipedia and make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link the different data sets on the Web to Wikipedia data. We hope that this work will make it easier for the huge amount of information in Wikipedia to be used in some new interesting ways.

Linked Data is about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data currently linked using other methods.
