DERI (LATC) launch

June 18, 2011 Comments off

Some of the DERI people (and others) involved in LATC have launched to counter the lack of rdfs in – the Microsoft/Google/Yahoo attempt to kickstart some RDFa publishing so their search engines can try and improve result relevancy. Some of the items in are quite simple, but thats probably a good thing : a large term set or number of properties is going to look daunting to anyone interested or someone starting out for the first time – and indeed this is the reason cited that it is not RDF (its microdata). And while I agree with Michael Bergman that it is more than likely another step towards structured/linked/common/open data, adopters urgently need a combination of

  1. Tools (or better still no tools, just an unobtrusive natural way to author microdata or rdfa) and
  2. a Reason to do it – payback
  3. Support in search UIs to specify vocabulary items

I’d like a wordpress plugin for instance, but then I’d need to host an instance myself or find a hoster that allows plugins because doesnt allow it. I’d also like to think that if I placed some RDFa in my blog that it would get higher a ranking in Search results (it should) but this blog is pretty specialised anyway and its not commercially oriented so Im happy enough with keyword based results anyway.

So, I’m not going to be doing it too soon, and thats the problem really. Or is it ? This post isn’t data really, but it does have links and it does talk about concepts, people, technology problems. If I could mark them up with tags and attributes that define what I am talking about then it would mean that I could tell those search engines and crawlers what I am talking about rather than hoping they can work it out from the title, the links I have chosen, then feedback comments and so on. Then people looking for these particular topics could find or stumble upon this post more easily. So, while there is some data here, arguably I don’t see it that way, and even if I think there might be a good Reason to do it, it’s too hard without the Tools

So I wonder finally, if I was to mark up one of these people mentioned in this post with name,address, affiliation,organisation and so on, would the search engine UIs allow me to use this vocabulary directly – I want to find articles about DERI say, would the search drop down prompt me with itemprop="EducationalOrganization" – so that I’d then only get results that have been marked up with this microdata property and not with things that are about the Deri vineyard in wales, punto deri, courtney deri and so on ?

Sindice kinda does this, couldn’t the Goog do it too ??? Or indicate which results are microdata’d, or allow a keyword predicate (like site: say), or allow the results to be filtered (like Search Tools in the left column). The point for me is that is only half or less than half the story – the search engines need to Support the initiative by making it available at query time, and to allow their results to manipulated in terms of microdata/rdfs too. Then I might be more tempted to markup my posts in microdata,rdfs,microformat or whatever, and I might create some extensions to the schemas and contribute a bit more, and my post might get more traffic in the long tail, that traffic would be more valuable, my ad revenue might go up (if I had ads for myself !), and the ECB might drop their interest rates. Well, maybe not, but they’re not listening to anythine else, perhaps some structured data might persuade them. It is the future after all.


Cisco go Social Semantic

February 22, 2011 Comments off

An announcement today[1/2]* of a cash injection to DERI from Cisco in respect of developing Cisco Quad[3] with a Semantic angle (SIOC no doubt) and Data Integration/Recommendation/Social-Network-Analysis with the proposed ADVANSSE project.[4,5]


Quad boasts standards like JSR-168, JSR-286, OpenSocial integration, XMPP, CMIS[6], but seems proprietary[7], and perhaps stuck with MS Exchange. Could this be a move to open it up for variegated enterprise, ECM and Web 3.0 [8]?

Google Fund Social Network Semantic Research at DERI

December 16, 2010 Comments off

An announcement today [1] that Google will fund a team led by Dr Alexandre Passant [2] on mobile social network applications. I wonder how much it will be like my own SkyTwenty platform [3] – far from being a social networking or blogging system but a mobile location service, with anonymity, access control and data shrouding. The DERI work is apparently going to build on some Google tech – “PubSubHubbub”[4] – and DERIs own hub based mobile blogging service – SMOB[5] – v2 of which was released in Jan 2010, integrates with Sindice. Distributed storage, Git like ? What about anonymity, provenance, trust, security, and scalabilty ?


Drupal 7 on Ubuntu 10.10 or 10.04 for SPARQL federation

October 28, 2010 3 comments

Quick steps to install Drupal 7

This, so you can use the SPARQL federating plugin

First install ubuntu ! 10.10 isnt much over 10.04, perhaps less even, so go with what you have v10-wise.


Now you need apache,mysql,php and drupal, database setup (ie LAMP + drupal). Then and a variety sparql modules and support.

In short

  1. Install LAMP
  2. Setup MySQL (or create a database for it)
  3. Download and Setup Drupal (or update/upgrade)
  4. Configure Drupal
  5. Add modules

In some more detail

  1. Install Lamp
  2. Install PHP gd – you’ll get errors about it during Drupal install otherwise
  3. Setup mysql with database called d7 and admin user drupal
    1. create database d7
    2. grant all privileges on d7 to drupal@localhost identified by ‘password’ -if you get into trouble install phpmyadmin
  4. download drupal7, expand and move the expanded dir into the docroot/cms (you may need sudo for all of this)
    1. gzip -dc drupal.*.*.tar.gz | tar -xvf -
    2. mkdir /var/www/cms
    3. cd drupal.*.*
    4. mv * /var/www/cms
    5. read the README about creating default site and perms
  5. take a breath
  6. restart apache for the hell of it - sudo /etc/init.d/apache2 restart
  7. go to and create the first site by following the steps
  8. reset perms as per readme on settings.php

now find the SPARQL plugin [1,2] that Lin at DERI created and get to work on content-types[3]……

I’ve left messages but haven’t had a response yet – Sparql Views as it is on GitHub Jan 2011 won’t install on the official Drupal7 release (drush doesnt like it either, it seems). But theres also VARQL[4], built on top of what Lin did, that might be good for you.

There are dependencies you should be prepared to install РViews (not unsurprisingly), Dialog [5], Chaos Tools Suite [6] (maybe  RDFx [7] РSparql Views has it, needs it, but Drupal7 has some conflict either at install or runtime Рneeds more investigation).

And you’ll need to download and manually install, as ftp to localhost, using the UI installer won’t work (at least not for me on Ubuntu 10.04/10).¬† Relying on ftp is just a bad way of installing things IMO.

Update rather than Upgrade

FYI : I easily updated (not upgraded [9]) my Drupal7 Beta to official release byfollowing Yodi Aditya’s instructions [8]
