TransFormr version 2.6

TransFormr is a simple toolkit that uses PHP and XSLT for extracting and transforming microformats http://microformats.org/.

Microformats that are supported by this transformer are:

Microformats that are supported by this transformr but are classed as Experimental and should not be used in a production environment because they may be removed or updated at any time are:

Non microformats supported by this transformer are:

Installation

You must have PHP version 5.2.0 or higher with XSLT enabled to run TransFormr.

  • Download the latest version of Transformr from http://github.com/WebOrganics/TransFormr.
  • Unpack the entire contents of the file called WebOrganics-TransFormr-XXXXX to your webserver either into its own directory or the the root of your directory (dedicated transformers only).
  • Take a look at the settings in index.php and change to suit (everything should work fine without altering anything).
  • If you plan to use the ARC2 store, enter your database, user, pass and hosts settings in /app/config.php and check that the dump folder is writable by the webserver.
  • Surf your way to wherever you unpacked your file eg: http://example.com/transformr/ .
  • Enter a url, Have fun transforming some microformats ;)

Conversions

Main conversions are:

  • Detect => Detect all.
  • hCard => vCard (.vcf), RDF, rdfjson, ntriples, turtle, html ( microdata ) or RDFa.
  • hCalendar => iCal (.ics), RDF, rdfjson, ntriples, turtle, html ( microdata ) or RDFa.
  • hAtom => Atom.
  • hAtom + rel-enclosure => RSS2.
  • hReview => RDF, rdfjson, ntriples, turtle, html ( microdata ) or RDFa.
  • Geo => KML.
  • hAudio => RSS2.

Experimental conversions are:

  • hAudio => XSPF.
  • hAudio => MO (Music Ontology).
  • hAtom => SIOC, rdfjson, ntriples, turtle, html ( microdata ) or RDFa.
  • hCard + XFN => FOAF, rdfjson, ntriples, turtle, html ( microdata ) or RDFa.

Other non microformat conversions

  • OGP ( Facebook Open Graph Protocol ) => RDF, rdfjson, ntriples, turtle, html ( microdata ) or RDFa.
  • RDFa => RDF, rdfjson, ntriples, turtle, or html ( microdata ).
  • eRDF => RDF, rdfjson, ntriples, turtle, html ( microdata ) or RDFa.
  • Microdata => JSON.

Transformr Conversion urls

RDF output Options:

ntriples, rdfa, turtle, rdfjson, and html (microdata)

Transformation Types are :

detect, hcard, hcard-rdf, hatom, hatom-rss2, geo, hcalendar, hcalendar-rdf, hreview, haudio-rss, mo-haudio, haudio-xspf, hfoaf, mrss, ogp-rdf, erdf, rdfa, hcard2qrcode and hatom-sioc.

Non RDF conversions,

  • index.php?type=(type)&url=http://(your page)

For all RDF conversions

  • index.php?type=(type)&output=(ntriples|rdfa|turtle|rdfjson|html)&url=http://(your page)

Apache Clean URLs

Non RDF conversions,

  • http://[transformr]/[type]/http://your page
  • http://[transformr]/[type]/referer ( transforms from refering url )
  • http://[transformr]/[type]/your fragment

For all RDF conversions

  • http://[transformr]/[type]/(ntriples|rdfa|turtle|rdfjson|html)/http://[your page]

By JSON Query.

Queries are formed using three properties, url (url of the webpage ) , type ( conversion type ) and output (output type), example

The output property is optional and may be omitted from a Query, example

You can also use describe queries on the ARC2 store ( if enabled ), this will return a document already extracted to the store, example

By SPARQL Query.

When you extract RDF using Transformr and the arc2 store is enabled, you can query the Transformr using the sparql endpoint, example

  • sparql/endpoint?query=CONSTRUCT { ?s ?p ?o } WHERE { GRAPH { ?s ?p ?o } }

All graphs are relative to the store, "type" is the type of RDF you extracted e.g hfoaf, rdfa ... etc, and the url of the page you extracted.

By Direct input.

You can also transform a fragment of html by direct input, this is intended to be used for testing you markup before publishing it live.

Future releases

Work is in progress supporting the Species Microformat http://microformats.org/wiki/species-strawman-01, hProduct http://microformats.org/wiki/hproduct + hCard Microformat to Good Relations and Data vocab transformation for Rich Snippets http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=99170.

Notes

  • 2.5 Added microdata to JSON transformation.
  • 2.4 Added value-title parsing for all microformats.
  • 2.3 Transformr is now Faster due to new caching action. Added support for Transforming by direct input, Some XSLT bugs fixed.
