The 9th ever VoCamp, and the first in Bristol. WhatIsVoCamp...?


Thursday 10th and Friday 11th September 2009. Note that this date has been changed due to a conflict


The following are outline timings for the event which are unlikely to change. Apart from these timings, exactly how we spend the time will largely be determined during the event.

Day 0[edit]

  • If you're around Wednesday evening and bored or lost contact Damian.

Day 1 (Thursday 10th September)[edit]

  • 10.45am Arrive, Coffee
  • 11am Introduction
  • 1pm Lunch
  • 3pm Coffee break
  • 5pm Finish

Day 2 (Friday 11th September)[edit]

  • 9:30am Arrive, Coffee
  • 12:30pm Lunch
  • 2:30pm Coffee break
  • 4pm Finish
  • Pub and Food outing for people who are around Friday evening.



Institute for Learning and Research Technology, University of Bristol.

On the first day we'll meet in the Morse Room, which is the first room on the right as you enter.

How to arrive[edit]



  • Ibis Bristol Centre: link - looks nearbyish, reasonably priced.




The ILRT is near the centre of Bristol.


Bristol Temple Meads is the most central station. The 8 and 9 buses go near the ILRT: get off at the top of Park Street (at the top of the hill, across the road from the big tower).


Bristol Airport is twenty minutes south of the city, by road. The Queens Road / Triangle West coach stop is close to the ILRT. If you are flying in try contacting Damian, who might be able to meet you.


Probably a bad idea; the traffic can be nasty. West End Car Park is the closest car park, although you can park in Berkeley Square (for a huge price).

The weekend[edit]

If you happen to be around between Friday evening and Sunday there are lots of things happening in Bristol.

Friday - Sunday[edit]

Beer festival at the Hillgrove and Green Man

Saturday - Sunday[edit]

Kite Festival

Interesting Games Festival


Bristol open doors day

Montpelier Bean Feast - bit obscure this one!


Here people can suggest vocabularies and other things to work on. Just put a topic in the list and other people can put their names behind it to indicate interest in that topic.

Vocabularies, etc. I want to to work on[edit]

  • Trust levels - i.e. who trusts whom and how much; can we represent trust levels that have been automatically calculated using degrees of separation. #swig log file, 1 June 2009
  • Expertise - e.g. <#Alice> is an expert at <#Cryptography> according to <#Bob>.
  • Public/Private Data - how to indicate that there is some related data behind eg. an OAuth endpoint.
  • Uncertainty representations for linked data - three possible areas to think about link weight/probability, override graphs (third party publishing of corrections to link sets or linked data sets), imprecise values
  • vocabulary profiles - we routinely reuse bits of existing vocabularies but have no formal way to document what particular bits a dataset is supposed to use, we can say "all eg:Persons have foaf:names" or we can import all of foaf but we can't say "if you want to name an eg:Person use foaf:name but some names may be missing" or just import a small fragment of a vocabulary.
  • json map representation - we need to enable non-RDF heads to work with linked data in some form, one thing that would be nice is a developer-friendly json encoding for RDF, such an encoding would omit a lot of URIs (or at least namespaces) so couldn't be turned back into RDF without help, a json mapping definition would be that help, the jsonmap vocabulary would be a way to write down that mapping definition.
  • recipes - there seem to be a few attempts at a simple vocabulary for recipes, but am not sure whether any of them are actually in serious use. I have some recipe data I want to model as RDF and so want to explore how best to do that -- LeighDodds
  • simple literal validation -- it'd be nice to be able to augment a schema to indicate how a literal might be validated by an application. E.g. checking for valid dates, regexps, etc. If there's existing work in this area then great, otherwise I'd like to sketch out something simple -- LeighDodds
  • derived data -- its sometimes useful to be able to store derived data in a model, e.g. a summary of some other values, or an A-Z index of resources based on, e.g. their titles. I'd like to work on a vocabulary or vocabularies that support this. -- LeighDodds
  • contextual data and preferences -- things like 'I watch this channel mostly in the evenings' 'I only watch TV on wednesdays' and also APML type stuff -- LibbyMiller
  • activities in RDF - see example here - main issue is making it extensible; in essence it's just the events vocab with some class types -- LibbyMiller
  • techniques for validation against schemas - a.k.a schemarama - I'd like to see if it would be helpful when creating a schema to also create queries for validating expected data. -- LibbyMiller

[The suggestions on uncertainty, vocabulary profiling and json mapping are just offered as food for thought. They may be a bit too inward looking. Would only suggest working on at most one of those. Dave]
