A lot of development is happening right now, so I thought I’d write a very quick summary to keep people informed.
Firstly, version 2.2 of the digress.it plugin was released yesterday. Remember that the JISCPress project bootstrapped the re-development of CommentPress (which has been at v1.4.1 for over a year now, I think) and we helped Eddie release digress.it v2 back in mid-August. We’ve had seven releases since then and v2.2 finally brings IE6 compatibility with it (IE7 came in v2.1.7). It’s feels stable now and provides pretty much the same experience across browsers. Performance is superb on a modern browser like Chrome 3, Firefox 3.5 or Safari 4. I’ve found that with wp-super-cache installed, too, pages are rendered in a snap.
I’ve also started to document the features that come with digress.it. Some of the really interesting stuff isn’t immediately obvious, like the incredible range of RSS feeds that are now available and the switches for RSS, JSON, XML, HTML and text. @paulgeraghty asked on Twitter whether this might be ‘micro-content’. I’d be interested to know if there are other CMS platforms that provide a formal method of obtaining document data at the paragraph level.
And remember that this is in addition to the full document or document section level RSS feeds that are built into WordPress.We’ve also introduced RSS feeds for each comment author and for the discussion around each paragraph, so if you want to follow one particular person or a discussion around one particular paragraph, you can.
We’re still working on ways to provide an easy way to copy and paste some code and embed a paragraph in your own site, while at the same time giving us a paragraph-level trackback. We’ve been trying various different methods but none of them have worked so far. We’re close though. If you’ve got any ideas for how this might be achieved, please leave a comment
Alex has been working hard on platform-wide features. He recently uploaded his ‘related documents’ code which looks across the entire platform of documents and makes suggestions for related document sections in the page sidebar. What’s especially interesting about this is the way this is achieved as a background service that runs periodically (you choose how often) and uses the OpenCalais API to provide contextual tags and the Yahoo! Term Extraction API to extract terms from the document. The relevancy of the tags received can be adjusted and author entered tags are also taken into account. These three different methods of mining the document ensure that the document sections that are ‘advertised’ to readers are relevant to the document they are currently reading.
Alex has also been working on integrating Triplify with JISCPress (and WordPressMU).
Triplify is a small plugin for Web applications, which reveals the semantic structures encoded in relational databases by making database content available as RDF, JSON or Linked Data.
In practice, this means that the semantic structures for each JISCPress document are now available as RDF triples. Click here and you’ll get an XML/RDF file for a single document. Alex has also written a plugin for WPMU which will work with Triplify and allow the document author to include a license of their own choice in the RDF. Finally, he’s been testing this with Talis’ Connected Commons triple store and now has the WPMU plugin pushing RDF triples to Talis where they can be queried and mashed up using the Talis API. His work on this should go up on our Google Code site in the next few days.
It all needs testing and tweaking a little more, but the substantial part of the work on these three plugins has been done and now it’s a matter of refining them and integrating the platform as a whole and documenting it thoroughly. We’re always interested in what you would like to see the JISCPress project achieve, so please take a look at our UserVoice site and add any suggestions you might have. We’re also tracking Issues about JISCPress on Google Code and Issues specifically about digress.it on the digress.it Google Code site. You can also get the development code for digress.it there, too.
