Ad hoc plumbing
Half an hour ago I discovered microrevie.ws, a Twitter-based review site. I couldn’t resist a quick play.
Like twitcrit 1.1 [currently not working *] and twitcrit 2.0, these reviews are authored in Twitter using a few (different) conventions. The microrevie.ws page is HTML with embedded microformats, which made me think right away of GRDDL. There were a couple of slight snags – the HTML isn’t XHTML its HTML5, and the page doesn’t declare HTML Meta Data profiles for the microformats. So here we go…
- live microrevie.ws page
- (1) piped through an online HTML Tidy service to yield a XHTML version
- (2) with a simple XSLT applied to insert @profile, using an online XSLT service to yield GRDDL-friendly XHTML
- (3) sent through triplr.org to yield RDF – here in Turtle syntax
Look ma…no import/export!
I’m pretty sure the GRDDL transformations aren’t 100% complete/accurate, and I couldn’t find one for hAtom which is used in the source, but there’s enough to show a lot of triple, generated live from the source simply by hooking together the URIs. Check this -
http://triplr.org/turtle/http://www.w3.org/2000/06/webdata/xslt?xslfile=http%3A%2F%2Fhyperdata.org%2Fxslt%2Fprofiles.xsl&xmlfile=http%3A%2F%2Fcgi.w3.org%2Fcgi-bin%2Ftidy%3FdocAddr%3Dhttp%253A%252F%252Fmicrorevie.ws%252F%26forceXML%3Don&transform=Submit
Not exactly the kind of thing you’d want on your business card, but it is bookmarkable/linkable.
Oh yeah – want a visualization with that? Flip triplr.org to /rdf/ and try it on the RDF Validator : http://www.w3.org/RDF/Validator/ARPServlet?URI=http%3A%2F%2Ftriplr.org%2Frdf%2Fhttp%3A%2F%2Fwww.w3.org%2F2000%2F06%2Fwebdata%2Fxslt%3Fxslfile%3Dhttp%253A%252F%252Fhyperdata.org%252Fxslt%252Fprofiles.xsl%26xmlfile%3Dhttp%253A%252F%252Fcgi.w3.org%252Fcgi-bin%252Ftidy%253FdocAddr%253Dhttp%25253A%25252F%25252Fmicrorevie.ws%25252F%2526forceXML%253Don%26transform%3DSubmit&PARSE=Parse+URI%3A+&TRIPLES_AND_GRAPH=PRINT_BOTH&FORMAT=PNG_EMBED
(scroll down towards the bottom & right to see the graph – it’s a bit big)
Should work in the Tabulator too.
Incidentally, there’s a neat trick at microrevie.ws: the subject of reviews gets posted to twitter as a simple string (ending with a ‘;’) but gets turned into a URI, e.g.
http://microrevie.ws/reviewables/Sparks+Alcoholic+Caffeinated+Beverage
Could come in handy for those times you really want a literal as the subject of a triple. Right now microrevie.ws has Google hooked up to help you find out what the thing is. Making that more explicit seems like it might be a job for Open Linking Data…
* I’m pretty sure there won’t be much difference in complexity of the operational code between twitcrit 1.1 and twitcrit 2.0. One possible explanation for the reason the latter is still running (even though I haven’t looked at it in months) and the former isn’t might be that the code proper in the working version is just a simple bit of Python, loosely coupled to some Software as a Service doing storage + SPARQL elsewhere (it’s on the Talis Platform). If I’d had to run that bit of infrastructure myself, I doubt very much whether that’d still be running.
