Exciting changes at Data.Southampton.ac.uk!
After some heated debate after the backlash against me for my recent
comments about PDF, I've been forced to shift to recommending PDF as the
preferred format for the data.southampton.ac.uk site, both for
publishing and importing data.
There are some issues with this and I know not every one will be happy
with the decision; it wasn't easy to make... but on reflection, however,
it's the right one. It is much easier for non programmers (the majority
of people) to work with PDF documents and they are supported by pretty
much every platform you can think of with a choice of tools and the
benefit of familiarity.
We've provided a wrapper around 4store to make PDF the default output mode:

Re: [ANN] Linked Open Colors
Ola Sergio Very cool ... and could be actually useful, so maybe less a joke than it seems Bernard 2011/4/1 Sergio Fernández sergio.fernan...@fundacionctic.org Hi, for giving some color to the semantic web folks, we are happy to announce the release the Linked Open Colors dataset [1]. The Linked Open Colors project offers tons of facts about colors, all readily available as Linked Open Data, linking with other relevant datasets such as dbpedia. The dataset and its publication mechanisms have been pedantically checked, and we expect no errors in the triples; if you do find some, please let us know. This project is highly inspired by Linked Open Numbers project [2]. Happy April Fools' Day!

Re: Exciting changes at Data.Southampton.ac.uk!
I'll put this onto our todo list, just under content negotiation on
Gopher URIs
Joking aside, we may need to use the open data in pages created in
SharePoint. A SOAP wrapper for SPARQL may well be the best solution to
this...

Re: Exciting changes at Data.Southampton.ac.uk!
Christopher,
I really don't see why I should have to reengineer my entire toolchain
simply to consume your proprietary format. It is well known that the
standard for information interchange is the Microsoft Word 97 document
format which is easily read by every popular computing package. I for one
will not be submitting to the opression of PDF.

That certainly sounds like something we should look into. Does MSWord 97
support anything similar? Perhaps we have to consider supporting both
Word97 and PDF to make the service available to all users.

Hyperlinks in this PDF point to sources described in formats as heterogenous as
HTML, RDF or JPG.
Could you also encapsulate them in PDF to make the job of the developer easier
by dealing with a single format ?

Dear all, Last year, we published the Linked Open Numbers paper [1] which was a big success in the Linked Data community. This year, we do not have a Linked Data or SemWeb related article but have an even bigger result in our annual journal [2]. Moreover, the Wall Street Journal announced the issue in advance [3].

RE: [ANN] Linked Open Colors
This is very useful Chris, however I think it would also be useful to relate pixels by spatial predicates.

Hi guys, the LDoW2011 data is being imported into data.semanticweb.org (just like the data from 2010), so any URIs used on the LDoW website resolve nicely. However, there are a few housekeeping triples that the LDoW dataset is missing (graph name, workshop acronym, etc.), which means that it doesn't show up properly in on the data.semanticweb.org HTML interface. @Tom, if you're interested in adding this data to the LDoW pages, let me know!

Subject: Exciting changes at Data.Southampton.ac.uk!
After some heated debate after the backlash against me for my recent
comments about PDF, I've been forced to shift to recommending PDF as the
preferred format for the data.southampton.ac.uk site, both for
publishing and importing data.
There are some issues with this and I know not every one will be happy
with the decision; it wasn't easy to make... but on reflection, however,
it's the right one. It is much easier for non programmers (the majority
of people) to work with PDF documents and they are supported by pretty
much every platform you can think of with a choice of tools and the
benefit of familiarity.
We've provided a wrapper around 4store to make PDF the default output mode:
http://sparql.data.southampton.ac.uk/?query=PREFIX+soton%3A+%3Chttp%3A%2F%2Fid.southampton.ac.uk%2Fns%2F%3E%0D%0APREFIX+foaf%3A+%3Chttp%3A%2F%2Fxmlns.com%2Ffoaf%2F0.1%2F%3E%0D%0APREFIX+skos%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2004%2F02%2Fskos%2Fcore%23%3E%0D%0APREFIX+geo%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2003%2F01%2Fgeo%2Fwgs84_pos%23%3E%0D%0APREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E%0D%0APREFIX+org%3A+%3Chttp%3A%2F%2Fwww.w3.org%2Fns%2Forg%23%3E%0D%0APREFIX+spacerel%3A+%3Chttp%3A%2F%2Fdata.ordnancesurvey.co.uk%2Fontology%2Fspatialrelations%2F%3E%0D%0APREFIX+ep%3A+%3Chttp%3A%2F%2Feprints.org%2Fontology%2F%3E%0D%0APREFIX+dct%3A+%3Chttp%3A%2F%2Fpurl.org%2Fdc%2Fterms%2F%3E%0D%0APREFIX+bibo%3A+%3Chttp%3A%2F%2Fpurl.org%2Fontology%2Fbibo%2F%3E%0D%0APREFIX+owl%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2002%2F07%2Fowl%23%3E%0D%0A%0D%0ASELECT+%3Fs+WHERE+{%0D%0A%3Fs+%3Fp+%3Fo+.%0D%0A}+LIMIT+10output=pdfjsonp=#results_table
And most information URIs can now be resolved to PDF, but we are
sticking to HTML as the default (for now)

Re: [ANN] Linked Open Colors
Hi Sergio, Thanks for the update about this new, much needed service! While perusing the data from the command line with rapper I noticed that: http://data.colourphon.co.uk/id/colourscheme/triadic/ff6347 rdfs:label triadic colours to compliment Coral (ff6347) . ISO 01.070 [1] clearly defines this color as Tomato. I think we can all agree that the identity of colors is a solved problem, and it would be great if this Linked Data service could be updated to reflect this. I started a Doodle Poll to see if we can find a time to meet to discuss whether a W3C Working Group or Incubator Group might be needed to resolve this issue. //Ed [1] http://bit.ly/gWCSql [2] http://www.doodle.com/geyvyrx4wzgvky5s

Also, we have an Entity ID (URI based Named Ref): http://labs.mondeca.com/dataset/lov/lov#CITY, and we (hopefully most Linked Data folk) kinda know said Entities representation (in the form of a linked data graph pictorial) is accessible from the Address (URL): http://labs.mondeca.com/dataset/lov/lov, but for absolute clarity (human and machines) you should add a wdrs:describedby relation of the form: http://labs.mondeca.com/dataset/lov/lov#CITY http://labs.mondeca.com/dataset/lov/lov#CITY wdrs:describedby http://labs.mondeca.com/dataset/lov/lov http://labs.mondeca.com/dataset/lov/lov .

The web of data is based on datasets publication. When building a dataset some questions arise: which existing vocabularies will be the best-suited for my needs? To facilitate this task we propose the Linked Open Vocabularies (LOV) dataset [1]. It identifies the defined vocabularies for data description but also the relationships between these vocabularies. The work within the LOV is not exhaustive but, by suggesting us some vocabulary modifications and/or creations, we could improve this dataset. You could access this dataset via an RDF/XML file [2] and via a SPARQL Endpoint [3].

Missing a triple such as http://dbpedia.org/ontology/rdfs:isDefinedByfoo I've got at least a version number :) So where is the RDF file containing the whole ontology? [1] references [2], which is a zipped file of the DBPedia Ontology. However, you are absolutely right, re. Linked Data publishing principles it might beneficial if, e.g., curl -H Accept: application/rdf+xml http://dbpedia.org/ontology/ or curl -H Accept: application/rdf+xml http://dbpedia.org/ontology/Person would resolve to a RDF/XML serialized description. It is a basic requirement especially re. Semantic Web ontology deployment to serve semantic graphs in different serializations formats. You are also right re. the application of rdfs:isDefinedBy for universals that are part of this ontology.
